I have always a slight feeling of pity for the man who has no knowledge of chess, just as I would pity the man who has remained ignorant of love. Chess, like love, like music, has the power to make man happy.

It is not enough to be a good player... You must also play well.

It cannot be too greatly emphasized that the most important role in pawn endings is played by the king.

When you see a good move, sit on your hands and see if you can find a better one.

When you don't know what to do, wait for your opponent to get an idea; it is sure to be bad.

You can move pieces on the above diagrams Black will try to defend, and stop doing so when it is mate.

Strategy board game

Chess is a two-player strategy board game played on a checkered board with 64squares arranged in an 88 grid.[1] The game is played by millions of people worldwide. Chess is believed to be derived from the Indian game chaturanga sometime before the 7thcentury. Chaturanga is also the likely ancestor of the Eastern strategy games xiangqi (Chinese chess), janggi (Korean chess), and shogi (Japanese chess). Chess reached Europe by the 9thcentury, due to the Umayyad conquest of Hispania. The pieces assumed their current powers in Spain in the late 15thcentury; the modern rules were standardized in the 19thcentury.

Play involves no hidden information. Each player begins with 16 pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns. Each piece type moves differently, with the most powerful being the queen and the least powerful the pawn. The objective is to checkmate[note 1] the opponent's king by placing it under an inescapable threat of capture. To this end, a player's pieces are used to attack and capture the opponent's pieces, while supporting each other. During the game, play typically involves exchanging pieces for the opponent's similar pieces, and finding and engineering opportunities to trade advantageously or to get a better position. In addition to checkmate, a player wins the game if the opponent resigns, or, in a timed game, runs out of time. There are also several ways that a game can end in a draw.

The first generally recognized World Chess Champion, Wilhelm Steinitz, claimed his title in 1886. Since 1948, the World Championship has been regulated by the Fdration Internationale des checs (FIDE), the game's international governing body. FIDE also awards life-time master titles to skilled players, the highest of which is Grandmaster (GM). Many national chess organizations have a title system of their own. FIDE also organizes the Women's World Championship, the World Junior Championship, the World Senior Championship, the Blitz and Rapid World Championships, and the Chess Olympiad, a popular competition among international teams. FIDE is a member of the International Olympic Committee, which can be considered recognition of chess as a sport.[3] Several national sporting bodies (e.g. the Spanish Consejo Superior de Deportes[4]) also recognize chess as a sport. Chess was included in the 2006 and 2010 Asian Games. There is also a Correspondence Chess World Championship and a World Computer Chess Championship. Online chess has opened amateur and professional competition to a wide and varied group of players.

Since the second half of the 20th century, chess engines have been programmed to play with increasing success, to the point where the strongest programs play at a higher level than the best human players. Since the 1990s, computer analysis has contributed significantly to chess theory, particularly in the endgame. The IBM computer Deep Blue was the first machine to overcome a reigning World Chess Champion in a match when it defeated Garry Kasparov in 1997. The rise of strong chess engines runnable on hand-held devices has led to increasing concern about cheating during tournaments.

There are many variants of chess that utilize different rules, pieces, or boards. One of these, Fischer Random Chess, has gained widespread popularity and official FIDE recognition.

The rules of chess are published by FIDE (Fdration Internationale des checs), chess's international governing body, in its Handbook.[5] Rules published by national governing bodies, or by unaffiliated chess organizations, commercial publishers, etc., may differ. FIDE's rules were most recently revised in 2018.

Initial position, first (bottom) row: rook, knight, bishop, queen, king, bishop, knight, and rook; second row: pawns

By convention, chess game pieces are divided into white and black sets. Each set consists of 16 pieces: one king, one queen, two rooks, two bishops, two knights, and eight pawns. The pieces are set out as shown in the diagram and photo. The players of the sets are referred to as White and Black, respectively.

The game is played on a square board of eight rows (called ranks, denoted 1 to 8 from bottom to top according to White's perspective) and eight columns (called files, denoted a to h from left to right according to White's perspective). The 64 squares alternate in color and are referred to as light and dark squares. The chessboard is placed with a light square at the right-hand corner nearest to each player. Thus, each queen starts on a square of its own color (the white queen on a light square; the black queen on a dark square).

In competitive games, the colors are allocated by the organizers; in informal games, the colors are usually decided randomly, for example by coin toss, or by one player's concealing a white and black pawn in either hand and having the opponent choose. White moves first, after which players alternate turns, moving one piece per turn (except for castling, when two pieces are moved). A piece is moved to either an unoccupied square or one occupied by an opponent's piece, which is captured and removed from play. With the sole exception of en passant, all pieces capture by moving to the square that the opponent's piece occupies.

Moving is compulsory; it is illegal to skip a turn, even when having to move is detrimental. A player may not make any move that would put or leave the player's own king in check. If the player to move has no legal move, the game is over; the result is either checkmate (a loss for the player with no legal move) if the king is in check, or stalemate (a draw) if the king is not.

Each piece has its own way of moving. In the diagrams, the dots mark the squares to which the piece can move if there are no intervening piece(s) of either color (except the knight, which leaps over any intervening pieces).

Once in every game, each king can make a special move, known as castling. Castling consists of moving the king two squares along the first rank toward a rook (that is on the player's first rank and then placing the rook on the last square that the king just crossed. Castling is permissible if the following conditions are met:[6]

When a pawn makes a two-step advance from its starting position and there is an opponent's pawn on a square next to the destination square on an adjacent file, then the opponent's pawn can capture it en passant ("in passing"), moving to the square the pawn passed over. This can be done only on the very next turn; otherwise the right to do so is forfeited. For example, in the animated diagram, the black pawn advances two steps from g7 to g5, and the white pawn on f5 can take it en passant on g6 (but only on White's next move).

When a pawn advances to the eighth rank, as a part of the move it is promoted and must be exchanged for the player's choice of queen, rook, bishop, or knight of the same color. Usually, the pawn is chosen to be promoted to a queen, but in some cases another piece is chosen; this is called underpromotion. In the animated diagram, the pawn on c7 can be advanced to the eighth rank and be promoted. There is no restriction on the piece promoted to, so it is possible to have more pieces of the same type than at the start of the game (e.g., two or more queens).

When a king is under immediate attack by one or two of the opponent's pieces, it is said to be in check. A move in response to a check is legal only if it results in a position where the king is no longer in check. This can involve capturing the checking piece; interposing a piece between the checking piece and the king (which is possible only if the attacking piece is a queen, rook, or bishop and there is a square between it and the king); or moving the king to a square where it is not under attack. Castling is not a permissible response to a check.

The object of the game is to checkmate the opponent; this occurs when the opponent's king is in check, and there is no legal way to remove it from attack. It is never legal for a player to make a move that puts or leaves the player's own king in check. In casual games it is common to announce "check" when putting the opponent's king in check, but this is not required by the rules of chess, and is not usually done in tournaments.

Games can be won in the following ways:

There are several ways games can end in a draw:

In competition, chess games are played with a time control. If a player's time runs out before the game is completed, the game is automatically lost (provided the opponent has enough pieces left to deliver checkmate). The duration of a game ranges from long (or "classical") games, which can take up to seven hours (even longer if adjournments are permitted), to bullet chess (under 3minutes per player for the entire game). Intermediate between these are rapid chess games, lasting between 20minutes and two hours per game, a popular time control in amateur weekend tournaments.

Time is controlled using a chess clock that has two displays, one for each player's remaining time. Analog chess clocks have been largely replaced by digital clocks, which allow for time controls with increments.

Time controls are also enforced in correspondence chess competition. A typical time control is 50 days for every 10 moves.

Chess is believed to have originated in Eastern India, c. 280550,[9] in the Gupta Empire,[10][11][12][13] where its early form in the 6thcentury was known as chaturaga (Sanskrit: ), literally four divisions [of the military] infantry, cavalry, elephants, and chariotry, represented by the pieces that would evolve into the modern pawn, knight, bishop, and rook, respectively. Thence it spread eastward and westward along the Silk Road. The earliest evidence of chess is found in the nearby Sasanian Persia around 600, where the game came to be known by the name chatrang. Chatrang was taken up by the Muslim world after the Islamic conquest of Persia (63344), where it was then named shatranj, with the pieces largely retaining their Persian names. In Spanish "shatranj" was rendered as ajedrez ("al-shatranj"), in Portuguese as xadrez, and in Greek as (zatrikion, which comes directly from the Persian chatrang),[14] but in the rest of Europe it was replaced by versions of the Persian shh ("king"), which was familiar as an exclamation and became the English words "check" and "chess".[note 3]

The oldest archaeological chess artifacts, ivory pieces, were excavated in ancient Afrasiab, today's Samarkand, in Uzbekistan, central Asia, and date to about 760, with some of them possibly older. The oldest known chess manual was in Arabic and dates to 840850, written by al-Adli ar-Rumi (800870), a renowned Arab chess player, titled Kitab ash-shatranj (Book of the chess). This is a lost manuscript, but referenced in later works. The eastern migration of chess, into China and Southeast Asia, has even less documentation than its migration west. The first reference to Chinese chess, called xingq , appears in a book entitled Xun gua l ("Record of the Mysterious and Strange"), dating to about 800. Alternatively, some contend that chess arose from Chinese chess or one of its predecessors,[15] although this has been contested.[16]

The game reached Western Europe and Russia by at least three routes, the earliest being in the 9thcentury. By the year 1000, it had spread throughout both Muslim Iberia and Latin Europe.[17] A Latin poem de scachis dated to the late 10th century has been preserved in Einsiedeln Abbey. A famous 13th-century manuscript covering shatranj, backgammon, and dice is known as the Libro de los juegos.

Around 1200, the rules of shatranj started to be modified in southern Europe, and around 1475, several major changes made the game essentially as it is known today.[17] These modern rules for the basic moves had been adopted in Italy and Spain.[18][19] Pawns gained the option of advancing two squares on their first move, while bishops and queens acquired their modern abilities. The queen replaced the earlier vizier chess piece towards the end of the 10thcentury and by the 15thcentury had become the most powerful piece;[20] consequently modern chess was referred to as "Queen's Chess" or "Mad Queen Chess".[21] Castling, derived from the "kings leap" usually in combination with a pawn or rook move to bring the king to safety, was introduced. These new rules quickly spread throughout western Europe.

Writings about the theory of how to play chess began to appear in the 15thcentury. The Repeticin de Amores y Arte de Ajedrez (Repetition of Love and the Art of Playing Chess) by Spanish churchman Luis Ramirez de Lucena was published in Salamanca in 1497.[19] Lucena and later masters like Portuguese Pedro Damiano, Italians Giovanni Leonardo Di Bona, Giulio Cesare Polerio and Gioachino Greco, and Spanish bishop Ruy Lpez de Segura developed elements of openings and started to analyze simple endgames.

In the 18th century, the center of European chess life moved from the Southern European countries to France. The two most important French masters were Franois-Andr Danican Philidor, a musician by profession, who discovered the importance of pawns for chess strategy, and later Louis-Charles Mah de La Bourdonnais, who won a famous series of matches with the Irish master Alexander McDonnell in 1834.[22] Centers of chess activity in this period were coffee houses in major European cities like Caf de la Rgence in Paris and Simpson's Divan in London.[23][24]

The rules concerning stalemate were finalized in the early 19thcentury. Also in the 19thcentury, the convention that White moves first was established (formerly either White or Black could move first). Finally the rules around castling were standardized variations in the castling rules had persisted in Italy until the late 19thcentury. The resulting standard game is sometimes referred to as Western chess[25] or international chess,[26] particularly in Asia where other games of the chess family such as xiangqi are prevalent. Since the 19thcentury, the only rule changes have been technical in nature, for example establishing the correct procedure for claiming a draw by repetition.

As the 19th century progressed, chess organization developed quickly. Many chess clubs, chess books, and chess journals appeared. There were correspondence matches between cities; for example, the London Chess Club played against the Edinburgh Chess Club in 1824.[27] Chess problems became a regular part of 19th-century newspapers; Bernhard Horwitz, Josef Kling, and Samuel Loyd composed some of the most influential problems. In 1843, von der Lasa published his and Bilguer's Handbuch des Schachspiels (Handbook of Chess), the first comprehensive manual of chess theory.

Chess was occasionally criticized in the 19th century as a waste of time.[28][29]

The first modern chess tournament was organized by Howard Staunton, a leading English chess player, and was held in London in 1851. It was won by the German Adolf Anderssen, who was hailed as the leading chess master. His brilliant, energetic attacking style was typical for the time.[30][31] Sparkling games like Anderssen's Immortal Game and Evergreen Game or Morphy's "Opera Game" were regarded as the highest possible summit of the chess art.[32]

The romantic era was characterized by opening gambits (sacrificing pawns or even pieces), daring attacks, and brazen sacrifices. Many elaborate and beautiful but unsound move sequences called "combinations" were played by the masters of the time. The game was played more for art than theory. A profound belief that chess merit resided in the players' genius rather than inherent in the position on the board pervaded chess practice.

Deeper insight into the nature of chess came with the American Paul Morphy, an extraordinary chess prodigy. Morphy won against all important competitors (except Staunton, who refused to play), including Anderssen, during his short chess career between 1857 and 1863. Morphy's success stemmed from a combination of brilliant attacks and sound strategy; he intuitively knew how to prepare attacks.[33]

Prague-born Wilhelm Steinitz beginning in 1873 described how to avoid weaknesses in one's own position and how to create and exploit such weaknesses in the opponent's position.[34] The scientific approach and positional understanding of Steinitz revolutionized the game. Steinitz was the first to break a position down into its components.[35] Before Steinitz, players brought their queen out early, did not completely develop their other pieces, and mounted a quick attack on the opposing king, which either succeeded or failed. The level of defense was poor and players did not form any deep plan.[36] In addition to his theoretical achievements, Steinitz founded an important tradition: his triumph over the leading German master Johannes Zukertort in 1886 is regarded as the first official World Chess Championship. Steinitz lost his crown in 1894 to a much younger player, the German mathematician Emanuel Lasker, who maintained this title for 27years, the longest tenure of any world champion.[37]

After the end of the 19th century, the number of master tournaments and matches held annually quickly grew. Some sources state that in 1914 the title of chess Grandmaster was first formally conferred by Tsar Nicholas II of Russia to Lasker, Capablanca, Alekhine, Tarrasch, and Marshall, but this is a disputed claim.[note 4] The tradition of awarding such titles was continued by the World Chess Federation (FIDE), founded in 1924 in Paris. In 1927, the Women's World Chess Championship was established; the first to hold the title was Czech-English master Vera Menchik.[38]

It took a prodigy from Cuba, Jos Ral Capablanca (World Champion 19211927), who loved simple positions and endgames, to end the German-speaking dominance in chess; he was undefeated in tournament play for eight years, until 1924. His successor was Russian-French Alexander Alekhine, a strong attacking player who died as the world champion in 1946. He briefly lost the title to Dutch player Max Euwe in 1935 and regained it two years later.[39]

Between the world wars, chess was revolutionized by the new theoretical school of so-called hypermodernists like Aron Nimzowitsch and Richard Rti. They advocated controlling the center of the board with distant pieces rather than with pawns, thus inviting opponents to occupy the center with pawns, which become objects of attack.[40]

After the death of Alekhine, a new World Champion was sought. FIDE, which has controlled the title since then (except for one interruption), ran a tournament of elite players. The winner of the 1948 tournament, Russian Mikhail Botvinnik, started an era of Soviet dominance in the chess world. Until the end of the Soviet Union, there was only one non-Soviet champion, American Bobby Fischer (champion 19721975).[41] Botvinnik revolutionized opening theory. Previously Black strove for equality, to neutralize White's first-move advantage. As Black, Botvinnik strove for the initiative from the beginning.[42] In the previous informal system of World Championships, the current champion decided which challenger he would play for the title and the challenger was forced to seek sponsors for the match. FIDE set up a new system of qualifying tournaments and matches. The world's strongest players were seeded into Interzonal tournaments, where they were joined by players who had qualified from Zonal tournaments. The leading finishers in these Interzonals would go on the "Candidates" stage, which was initially a tournament, and later a series of knockout matches. The winner of the Candidates would then play the reigning champion for the title. A champion defeated in a match had a right to play a rematch a year later. This system operated on a three-year cycle. Botvinnik participated in championship matches over a period of fifteen years. He won the world championship tournament in 1948 and retained the title in tied matches in 1951 and 1954. In 1957, he lost to Vasily Smyslov, but regained the title in a rematch in 1958. In 1960, he lost the title to the 23-year-old Latvian prodigy Mikhail Tal, an accomplished tactician and attacking player. Botvinnik again regained the title in a rematch in 1961.

Following the 1961 event, FIDE abolished the automatic right of a deposed champion to a rematch, and the next champion, Armenian Tigran Petrosian, a player renowned for his defensive and positional skills, held the title for two cycles, 19631969. His successor, Boris Spassky from Russia (champion 19691972), won games in both positional and sharp tactical style.[43] The next championship, the so-called Match of the Century, saw the first non-Soviet challenger since World War II, American Bobby Fischer, who defeated his Candidates opponents by unheard-of margins and clearly won the world championship match. In 1975, however, Fischer refused to defend his title against Soviet Anatoly Karpov when FIDE did not meet his demands, and Karpov obtained the title by default.[44] Fischer modernized many aspects of chess, especially by extensively preparing openings.[45]

Karpov defended his title twice against Viktor Korchnoi and dominated the 1970s and early 1980s with a string of tournament successes.[46] Karpov's reign finally ended in 1985 at the hands of Garry Kasparov, another Soviet player from Baku, Azerbaijan. Kasparov and Karpov contested five world title matches between 1984 and 1990; Karpov never won his title back.[47] In 1993, Garry Kasparov and Nigel Short broke with FIDE to organize their own match for the title and formed a competing Professional Chess Association (PCA). From then until 2006, there were two simultaneous World Champions and World Championships: the PCA or Classical champion extending the Steinitzian tradition in which the current champion plays a challenger in a series of many games, and the other following FIDE's new format of many players competing in a tournament to determine the champion. Kasparov lost his Classical title in 2000 to Vladimir Kramnik of Russia.[48] The World Chess Championship 2006, in which Kramnik beat the FIDE World Champion Veselin Topalov, reunified the titles and made Kramnik the undisputed World Chess Champion.[49] In September 2007, he lost the title to Viswanathan Anand of India, who won the championship tournament in Mexico City. Anand defended his title in the revenge match of 2008,[50] 2010 and 2012. In 2013, Magnus Carlsen beat Anand in the 2013 World Chess Championship.[51] He defended his title the following year, again against Anand. Carlsen confirmed his title in 2016 against the Russian Sergey Karjakin[52] and in 2018 against the American Fabiano Caruana,[53] in both occasions by a rapid tiebreaker match after equality in 12 games of classical time control, and is the reigning world champion.

In the Middle Ages and during the Renaissance, chess was a part of noble culture; it was used to teach war strategy and was dubbed the "King's Game".[54] Gentlemen are "to be meanly seene in the play at Chestes", says the overview at the beginning of Baldassare Castiglione's The Book of the Courtier (1528, English 1561 by Sir Thomas Hoby), but chess should not be a gentleman's main passion. Castiglione explains it further:

And what say you to the game at chestes? It is truely an honest kynde of enterteynmente and wittie, quoth Syr Friderick. But me think it hath a fault, whiche is, that a man may be to couning at it, for who ever will be excellent in the playe of chestes, I beleave he must beestowe much tyme about it, and applie it with so much study, that a man may assoone learne some noble scyence, or compase any other matter of importaunce, and yet in the ende in beestowing all that laboure, he knoweth no more but a game. Therfore in this I beleave there happeneth a very rare thing, namely, that the meane is more commendable, then the excellency.[55]

Many of the elaborate chess sets used by the aristocracy have been lost, but others partially survive, such as the Lewis chessmen.

Chess was often used as a basis of sermons on morality. An example is Liber de moribus hominum et officiis nobilium sive super ludo scacchorum ('Book of the customs of men and the duties of nobles or the Book of Chess'), written by an Italian Dominican monk Jacobus de Cessolis c.1300. This book was one of the most popular of the Middle Ages.[56] The work was translated into many other languages (the first printed edition was published at Utrecht in 1473) and was the basis for William Caxton's The Game and Playe of the Chesse (1474), one of the first books printed in English.[57] Different chess pieces were used as metaphors for different classes of people, and human duties were derived from the rules of the game or from visual properties of the chess pieces:[58]

The knyght ought to be made alle armed upon an hors in suche wyse that he haue an helme on his heed and a spere in his ryght hande/ and coueryd wyth his sheld/ a swerde and a mace on his lyft syde/ Cladd wyth an hawberk and plates to fore his breste/ legge harnoys on his legges/ Spores on his heelis on his handes his gauntelettes/ his hors well broken and taught and apte to bataylle and couerid with his armes/ whan the knyghtes ben maad they ben bayned or bathed/ that is the signe that they shold lede a newe lyf and newe maners/ also they wake alle the nyght in prayers and orysons vnto god that he wylle gyue hem grace that they may gete that thynge that they may not gete by nature/ The kynge or prynce gyrdeth a boute them a swerde in signe/ that they shold abyde and kepe hym of whom they take theyr dispenses and dignyte.[59]

Known in the circles of clerics, students, and merchants, chess entered into the popular culture of Middle Ages. An example is the 209th song of Carmina Burana from the 13thcentury, which starts with the names of chess pieces, Roch, pedites, regina...[60]

During the Age of Enlightenment, chess was viewed as a means of self-improvement. Benjamin Franklin, in his article "The Morals of Chess" (1750), wrote:

The Game of Chess is not merely an idle amusement; several very valuable qualities of the mind, useful in the course of human life, are to be acquired and strengthened by it, so as to become habits ready on all occasions; for life is a kind of Chess, in which we have often points to gain, and competitors or adversaries to contend with, and in which there is a vast variety of good and ill events, that are, in some degree, the effect of prudence, or the want of it. By playing at Chess then, we may learn:

I. Foresight, which looks a little into futurity, and considers the consequences that may attend an action [...]

II. Circumspection, which surveys the whole Chess-board, or scene of action: the relation of the several Pieces, and their situations [...]

III. Caution, not to make our moves too hastily [...][61]

With these or similar views, chess is taught to children in schools around the world today. Many schools host chess clubs, and there are many scholastic tournaments specifically for children. Tournaments are held regularly in many countries, hosted by organizations such as the United States Chess Federation and the National Scholastic Chess Foundation.[62]

Chess is often depicted in the arts; significant works where chess plays a key role range from Thomas Middleton's A Game at Chess to Through the Looking-Glass by Lewis Carroll, to Vladimir Nabokov's The Defense, to The Royal Game by Stefan Zweig. Chess is featured in films like Ingmar Bergman's The Seventh Seal and Satyajit Ray's The Chess Players.

Chess is also present in contemporary popular culture. For example, the characters in Star Trek play a futuristic version of the game called "Tri-Dimensional Chess". "Wizard's Chess" is featured in J.K. Rowling's Harry Potter plays. The hero of Searching for Bobby Fischer struggles against adopting the aggressive and misanthropic views of a world chess champion.[63] Chess is used as the core theme in the musical Chess by Tim Rice, Bjrn Ulvaeus, and Benny Andersson. The thriller film Knight Moves is about a chess grandmaster who is accused of being a serial killer. Pawn Sacrifice, starring Tobey Maguire as Bobby Fischer and Liev Schreiber as Boris Spassky, depicts the drama surrounding the 1972 World Chess Championship in Iceland during the Cold War.[64]

The game of chess, at times, has been discouraged by various religious authorities, including Jewish, Christian and Muslim. Jewish scholars Maimonides and Kalonymus ben Kalonymus both condemned chess, though the former only condemned it when played for money while the latter condemned it in all circumstances.[65] In medieval times both the Catholic and Orthodox churches condemned chess.[66] Though 16th century the Russian Orthodox Domostroy condemned the game, chess nevertheless remained popular in Russia.[67] In 1979, Iranian Ayatollah Ruhollah Khomeini ruled against chess,[68] but later allowed it as long as it did not involve gambling. Iran now has an active confederation for playing chess and sends players to international events.[69] Saudi Mufti Abdul-Aziz ash-Sheikh similar ruled against chess arguing it constituted gambling.[70] Iraqi Ayatollah Ali al-Sistani said chess was forbidden "even without placing a bet.[71]

Chess games and positions are recorded using a system of notation, most commonly algebraic chess notation.[72] Abbreviated algebraic (or short algebraic) notation generally records moves in the format:

The pieces are identified by their initials. In English, these are K (king), Q (queen), R (rook), B (bishop), and N (knight; N is used to avoid confusion with king). For example, Qg5 means "queen moves to the g-file, 5th rank" (that is, to the square g5). Chess literature published in other languages may use different initials for pieces, or figurine algebraic notation (FAN) may be used to avoid language issues. To resolve ambiguities, an additional letter or number is added to indicate the file or rank from which the piece moved (e.g. Ngf3 means "knight from the g-file moves to the square f3"; R1e2 means "rook on the first rank moves to e2"). The letter P for pawn is not used; so e4 means "pawn moves to the square e4".

If the piece makes a capture, "x" is inserted before the destination square. Thus Bxf3 means "bishop captures on f3". When a pawn makes a capture, the file from which the pawn departed is used in place of a piece initial, and ranks may be omitted if unambiguous. For example, exd5 (pawn on the e-file captures the piece on d5) or exd (pawn on the e-file captures a piece somewhere on the d-file). Particularly in Germany, some publications use ":" rather than "x" to indicate capture, but this is now rare. Some publications omit the capture symbol altogether; so exd5 would be rendered simply as ed.

If a pawn moves to its last rank, achieving promotion, the piece chosen is indicated after the move (for example, e1Q or e1=Q). Castling is indicated by the special notations 0-0 for kingside castling and 0-0-0 for queenside castling. An en passant capture is sometimes marked with the notation "e.p." A move that places the opponent's king in check usually has the notation "+" added (the notation "++" for a double check is considered obsolete). Checkmate can be indicated by "#". At the end of the game, "10" means White won, "01" means Black won, and "" indicates a draw.[73]

Chess moves can be annotated with punctuation marks and other symbols. (For example: "!" indicates a good move; "!!" an excellent move; "?" a mistake; "??" a blunder; "!?" an interesting move that may not be best; or "?!" a dubious move not easily refuted.[74])

For example, one variation of a simple trap known as the Scholar's mate (see animated diagram) can be recorded:

The text-based Portable Game Notation (PGN), which is understood by chess software, is based on short form English language algebraic notation.

Until about 1980, the majority of English language chess publications used a form of descriptive notation. In descriptive notation, files are named according to the piece which occupies the back rank at the start of the game, and each square has two different names depending on whether it is from White's or Black's point of view. For example, the square known as "e3" in algebraic notation is "K3" (King's 3rd) from White's point of view, and "K6" (King's 6th) from Black's point of view. When recording captures, the captured piece is named rather than the square on which it is captured (except to resolve ambiguities). Thus, Scholar's mate is rendered in descriptive notation:

A few players still prefer descriptive notation, but it is no longer recognized by FIDE.

Another system is ICCF numeric notation, recognized by the International Correspondence Chess Federation though its use is in decline. Squares are identified by numeric coordinates, for example a1 is "11" and h8 is "88". Moves are described by the "from" and "to" squares, e.g. the opening move 1.e4 is rendered as 1.5254. Captures are not indicated. Castling is described by the king's move only; e.g. 5171 for White castling kingside, 5838 for Black castling queenside.

A game of chess can generally be loosely subdivided into three phases or stages of play: the opening, followed by the middlegame, then last the endgame.

A chess opening is the group of initial moves of a game (the "opening moves"). Recognized sequences of opening moves are referred to as openings and have been given names such as the Ruy Lopez or Sicilian Defense. They are catalogued in reference works such as the Encyclopaedia of Chess Openings. There are dozens of different openings, varying widely in character from quiet positional play (for example, the Rti Opening) to very aggressive (the Latvian Gambit). In some opening lines, the exact sequence considered best for both sides has been worked out to more than 30 moves.[75] Professional players spend years studying openings and continue doing so throughout their careers, as opening theory continues to evolve.

The fundamental strategic aims of most openings are similar:[76]

Most players and theoreticians consider that White, by virtue of the first move, begins the game with a small advantage. This initially gives White the initiative.[77] Black usually strives to neutralize White's advantage and achieve equality, or to develop dynamic counterplay in an unbalanced position.

The middlegame is the part of the game which starts after the opening. There is no clear line between the opening and the middlegame, but typically the middlegame will start when most pieces have been developed. (Similarly, there is no clear transition from the middlegame to the endgame; see start of the endgame.) Because the opening theory has ended, players have to form plans based on the features of the position, and at the same time take into account the tactical possibilities of the position.[78] The middlegame is the phase in which most combinations occur. Combinations are a series of tactical moves executed to achieve some gain. Middlegame combinations are often connected with an attack against the opponent's king. Some typical patterns have their own names; for example, the Boden's Mate or the LaskerBauer combination.[79]

Specific plans or strategic themes will often arise from particular groups of openings which result in a specific type of pawn structure. An example is the minority attack, which is the attack of queenside pawns against an opponent who has more pawns on the queenside. The study of openings is therefore connected to the preparation of plans that are typical of the resulting middlegames.[80]

Another important strategic question in the middlegame is whether and how to reduce material and transition into an endgame (i.e. simplify). Minor material advantages can generally be transformed into victory only in an endgame, and therefore the stronger side must choose an appropriate way to achieve an ending. Not every reduction of material is good for this purpose; for example, if one side keeps a light-squared bishop and the opponent has a dark-squared one, the transformation into a bishops and pawns ending is usually advantageous for the weaker side only, because an endgame with bishops on opposite colors is likely to be a draw, even with an advantage of a pawn, or sometimes even with a two-pawn advantage.[81]

The side having to move is disadvantaged.

The endgame (also end game or ending) is the stage of the game when there are few pieces left on the board. There are three main strategic differences between earlier stages of the game and the endgame:[82]

Endgames can be classified according to the type of pieces remaining on the board. Basic checkmates are positions in which one side has only a king and the other side has one or two pieces and can checkmate the opposing king, with the pieces working together with their king. For example, king and pawn endgames involve only kings and pawns on one or both sides, and the task of the stronger side is to promote one of the pawns. Other more complicated endings are classified according to pieces on the board other than kings, such as "rook and pawn versus rook" endgames.

Chess strategy consists of setting and achieving long-term positioning advantages during the game for example, where to place different pieces while tactics concentrate on immediate maneuver. These two aspects of the gameplay cannot be completely separated, because strategic goals are mostly achieved through tactics, while the tactical opportunities are based on the previous strategy of play. A game of chess is normally divided into three phases: the opening, typically the first 10 moves, when players move their pieces to useful positions for the coming battle; the middlegame; and last the endgame, when most of the pieces are gone, kings typically take a more active part in the struggle, and pawn promotion is often decisive.

23.Bh5+ and now:

In chess, tactics in general concentrate on short-term actions so short-term that they can be calculated in advance by a human player or a computer. The possible depth of calculation depends on the player's ability. In quiet positions with many possibilities on both sides, a deep calculation is more difficult and may not be practical, while in positions with a limited number of forced variations, strong players can calculate long sequences of moves.

Theoreticians describe many elementary tactical methods and typical maneuvers, for example: pins, forks, skewers, batteries, discovered attacks (especially discovered checks), zwischenzugs, deflections, decoys, sacrifices, underminings, overloadings, and interferences.[84] Simple one-move or two-move tactical actions threats, exchanges of material, and double attacks can be combined into more complicated sequences of tactical maneuvers that are often forced from the point of view of one or both players.[85] A forced variation that involves a sacrifice and usually results in a tangible gain is called a combination.[85] Brilliant combinations such as those in the Immortal Game are considered beautiful and are admired by chess lovers. A common type of chess exercise, aimed at developing players' skills, is a position where a decisive combination is available and the challenge is to find it.[86]

Chess strategy is concerned with evaluation of chess positions and with setting up goals and long-term plans for the future play. During the evaluation, players must take into account numerous factors such as the value of the pieces on the board, control of the center and centralization, the pawn structure, king safety, and the control of key squares or groups of squares (for example, diagonals, open files, and dark or light squares).

The most basic step in evaluating a position is to count the total value of pieces of both sides.[87] The point values used for this purpose are based on experience; usually pawns are considered worth one point, knights and bishops about three points each, rooks about five points (the value difference between a rook and a bishop or knight being known as the exchange), and queens about nine points. The king is more valuable than all of the other pieces combined, since its checkmate loses the game. But in practical terms, in the endgame the king as a fighting piece is generally more powerful than a bishop or knight but less powerful than a rook.[88] These basic values are then modified by other factors like position of the piece (e.g. advanced pawns are usually more valuable than those on their initial squares), coordination between pieces (e.g. a pair of bishops usually coordinate better than a bishop and a knight), or the type of position (e.g. knights are generally better in closed positions with many pawns while bishops are more powerful in open positions).[89]

...and its pawn "Rauzer formation"

Another important factor in the evaluation of chess positions is the pawn structure (sometimes known as the pawn skeleton): the configuration of pawns on the chessboard.[91] Since pawns are the least mobile of the pieces, the pawn structure is relatively static and largely determines the strategic nature of the position. Weaknesses in the pawn structure, such as isolated, doubled, or backward pawns and holes, once created, are often permanent. Care must therefore be taken to avoid these weaknesses unless they are compensated by another valuable asset (for example, by the possibility of developing an attack).[92]

Contemporary chess is an organized sport with structured international and national leagues, tournaments, and congresses. Chess's international governing body is FIDE (Fdration Internationale des checs). Most countries have a national chess organization as well (such as the US Chess Federation and English Chess Federation) which in turn is a member of FIDE. FIDE is a member of the International Olympic Committee,[93] but the game of chess has never been part of the Olympic Games; chess does have its own Olympiad, held every two years as a team event.

The current World Chess Champion is Magnus Carlsen of Norway.[94] The reigning Women's World Champion is Hou Yifan from China.[95] The world's highest rated female player, Judit Polgr, has never participated in the Women's World Chess Championship, instead preferring to compete with the leading men and maintaining a ranking among the top male players.[96]

Other competitions for individuals include the World Junior Chess Championship, the European Individual Chess Championship, and the National Chess Championships. Invitation-only tournaments regularly attract the world's strongest players. Examples include Spain's Linares event, Monte Carlo's Melody Amber tournament, the Dortmund Sparkassen meeting, Sofia's M-tel Masters, and Wijk aan Zee's Tata Steel tournament.

Regular team chess events include the Chess Olympiad and the European Team Chess Championship. The World Chess Solving Championship and World Correspondence Chess Championships include both team and individual events.

Besides these prestigious competitions, there are thousands of other chess tournaments, matches, and festivals held around the world every year catering to players of all levels. Chess is promoted as a "mind sport" by the Mind Sports Organisation, alongside other mental-skill games such as contract bridge, Go, and Scrabble.

The best players can be awarded specific lifetime titles by the world chess organization FIDE:[97]

All the titles are open to men and women. Separate women-only titles, such as Woman Grandmaster (WGM), are available. Beginning with Nona Gaprindashvili in 1978, a number of women have earned the GM title, and most of the top ten women in 2006 hold the unrestricted GM title.[note 5]

As of 2018[update], there are 1725 active grandmasters and 3903 international masters in the world. The top three countries with the largest numbers of grandmasters are Russia, the United States, and Germany, with 251, 98, and 96, respectively.[98]

FIDE also awards titles for arbiters and trainers.[99][100]

International titles are awarded to composers and solvers of chess problems and to correspondence chess players (by the International Correspondence Chess Federation). National chess organizations may also award titles, usually to the advanced players still under the level needed for international titles; an example is the chess expert title used in the United States.

In order to rank players, FIDE, ICCF, and national chess organizations use the Elo rating system developed by Arpad Elo. Elo is a statistical system based on the assumption that the chess performance of each player in his or her games is a random variable. Arpad Elo thought of a player's true skill as the average of that player's performance random variable, and showed how to estimate the average from results of player's games. The US Chess Federation implemented Elo's suggestions in 1960, and the system quickly gained recognition as being both fairer and more accurate than older systems; it was adopted by FIDE in 1970.[note 6] A beginner or casual player typically has an Elo rating of less than 1000; an ordinary club player has a rating of about 1500, a strong club player about 2000, a grandmaster usually has a rating of over 2500, and an elite player has a rating of over 2700. The highest FIDE rating of all time, 2881, was achieved by Magnus Carlsen on the March 2014 FIDE rating list.[101]

Chess composition is the art of creating chess problems (also called chess compositions). The creator is known as a chess composer.[102] There are many types of chess problems; the two most important are:

Chess composition is a distinct branch of chess sport, and tournaments exist for both the composition and solving of chess problems.[105]

This is one of the most famous chess studies; it was published by Richard Rti 4 December 1921. It seems impossible to catch the advanced black pawn, while the black king can easily stop the white pawn. The solution is a diagonal advance, which brings the king to both pawns simultaneously:

Iranian Chess Official Fears Going Home Over Hijab Photo – The New York Times

A prominent Iranian chess official said she was afraid of returning to her country after an image of her, appearing not to wear a hijab at a world chess tournament, circulated online and in Iranian media.

At 32, Shohreh Bayat is one of the few top female chess arbiters in the world with the Category A classification, a distinction given to international chess referees who have shown an excellent command of the rules of the sport.

But she said discussions in Iranian media seemed more concerned with her hijab than her accomplishments, following a recent chess match during the Womens World Chess Championship.

After she finished presiding over the third round in Shanghai on Jan. 8, she said she turned on her phone and saw a picture of her during the tournament circulating on Iranian media, which is heavily monitored by the government.

In the photo, it appeared that her head was uncovered, a violation of Iranian law.

The accusation in these articles was that I deliberately had no head scarf in order to protest against the hijab, Ms. Bayat said in an email. I was shocked and panicked.

Now, Ms. Bayat feels she cant return to Iran.

Not wearing the hijab is a crime in Iran which is punishable by arrest, invalidation of the passport or prison, she said. I would love to return to Iran but only if Ill be safe.

Ms. Bayat told the BBC that she was in fact wearing the hijab in the photo, which, in the image, hung loosely on the back of her head. Generally, she said, she did not even like wearing the hijab.

I believe people must be free to choose what they want to wear, Ms. Bayat said in the email. I have never worn the hijab out of choice.

She told the BBC that after reading the news accounts in Iran, she decided to stop wearing the hijab so she could be myself.

Ms. Bayat said in her email that the Iranian chess federation asked her to issue a statement supporting the hijab, but she refused.

In my conscience, I could not do it, she said.

The Iranian chess federation did not respond to a request for comment.

It is frustrating that some people are more concerned with what I wear than in my achievements, Ms. Bayat said.

The three-week tournament between Ju Wenjun, the defending champion from China, and Aleksandra Goryachkina, a Russian champion, is now in Vladivostok and ends on Jan. 25.

Misha Friedman, press secretary for the International Chess Federation, said the organization had not heard from the Iranian government or any ministry official asking that Ms. Bayat be removed from the tournament.

We consider it that she is within the bounds of federation rules, he said, and were happy with the job that she is doing, so there is no problem from our perspective.

Being picked as chief arbiter of such a prestigious tournament is a tremendous honor, said Mr. Friedman, who compared it to refereeing the Super Bowl.

Nigel Short, a federation vice president, shared his support on Twitter for Ms. Bayat on Jan. 9, along with an image of her without the hijab.

He called her a great ambassador for her country.

The episode coincided with a statement by Kimia Alizadeh, a top Iranian athlete, who recently announced on Instagram that she was defecting from the country because leaders there had used her as a tool.

They took me wherever they wanted, she wrote. Whatever they said, I wore. Every sentence they ordered, I repeated.

Ms. Alizadeh, 21, who won the bronze medal in taekwondo at the 2016 Summer Games in Rio de Janeiro, is the only female athlete to win an Olympic medal for Iran.

My troubled spirit does not fit into your dirty economic channels and tight political lobbies, she wrote. I have no other wish except for taekwondo, security and a happy and healthy life.

Battles Of The Blindfold Chess Wars – Chess.com

My last article was about howGeorge Koltanowski slowly got better and better as a chess player; first in the early/mid 1920s (boring and slow), and then in 1928 when he embraced dynamics. Though he was a strong player at that point, he was even better with his eyes shut!

It was thought that Francois Philidor was the first person to challenge in two or three games without being able to see. However, blindfold chess was known far earlier by Arabian, Persian, Greek, Italian and even Spanish players. According to Muhammad bin Omar Kajina, there had been several players who would contest four or five blindfold games simultaneously in the 16th century.

After Philidor (he died in 1795), Alexander McDonnell was the best English player and a very strong blindfold player (McDonnell died in 1835). A famous quote by McDonnell is the joke that the only things which spoil chess are the board and men.

George Koltanowski. Photo via Wikipedia.

Though there are many ways to play blindfold, eventually certain basic rules were accepted. Here is what Koltanowski said about blindfold exhibitions:

Let me try to explain what a blindfold exhibition represents. I sit with my back to the players and tell my moves to the teller, who goes from board to board making the moves for me. He tells me that moves my opponents have made. I give my replies as quickly as possible. I see no board and write nothing down on paper. This is pure memory, a king of momentary memory which has been developed to such an extent that I can now play 15 games simultaneously each day without feeling the strain.

Eventually, using those particular rules (there are other rules too), the chess gods jumped into the fray!

Finally, I have to mention Janos Flesch (Budapest), who played 52 games blindfold in 1960. However, it wasnt accepted since he was allowed to consult the scoresheets during the games.

In my first article about Koltanowski, I only looked for tournament games and nothing about blindfold. However, Kolty was not just playing tournament chess; he was also starting to train himself for blindfold. He played some blindfold games (to really see what he could do) and in 1921 he and some of his friend were addicted.

This is what Koltanowski said:

We played blindfold chess wherever we weredancing, hiking, on buses and trains; wherever two of us happened to be, we would begin a blindfold game. All over Antwerp people shook their heads at this babbling crew.

A year later I was playing 16 games blindfold, which represented a new Belgian record. In 1924, while in the Belgian army, I played 20 at Naur, a sorts of pay-off for having nothing to do but peel potatoes for two hours a day.

Here are some of Koltanowskis best (or most fun) blindfold games. Oh, every time you see a "Mynheer X" or "Senor X," it means Kolty didn't know the man's name.

GAME 1:

GAME 2:

GAME 3:

GAME 4:

Black played very well, but a blunder gave Kolty the chance that he was hoping for.

GAME 5:

Kolty said, This was an exhibition in which I played against eight consulting teams of two players each. Dont forget that White was blindfolded, while his two opponents could see.

GAME 6:

GAME 7:

GAME 8:

GAME 9:

Kolty really enjoyed this game, and he gave quite a few notes. You will like the game and notes!

GAME 10:

GAME 11:

GAME 12:

GAME 13:

GAME 14:

GAME 15:

Kolty:The 1937 tour created some sort of a world record. I played 26 exhibitions in 26 days in 26 different cities, each nights event being a 10-board blindfold demonstration. I made a score of 94 percent in the 260 games, a result which is comparable to the best obtained in any chess masters tour on any country!

GAME 16:

GAME 17:

GAME 18:

Koltanowski, who had adventures in all of Europe and South America, permanently moved to San Francisco in 1947. He died in 2000 (96 years old).

‘I Have a Dream’ tournament calling all local chess players – Herald and News

Community chess players are invited to honor nonviolent freedom fighter Martin Luther King Jr., by playing their peaceful war game at the 25th annual I Have a Dream chess tournament, from 8:30 a.m. to 5 p.m. Monday, Jan. 20, at Klamath Union High School, according to a news release.

The event on the 25th anniversary of the Martin Luther King Jr. holiday is a five-round tournament that will prepare players for upcoming tournaments hosted by Chess for Success and the Oregon Scholastic Chess Federation. It is open to any age and will be Northwest Special Recreation Association rated. Unranked players will be grouped based upon ability.

There is a $10 fee for pre-registered players in kindergarten through the 12th grade, payable on the day of the tournament. To pre-register by 5 p.m. Sunday, Jan. 19, players are asked to send their name, grade, school and contact information to tournament organizer Ciara Dykstra at cecedee224@gmail.com.

Late registrants and all adult players will be charged $15 at the door between 8:30 and 9:30 a.m. Registration will take place outside Pel Court.

Chess really brings people together, says Dykstra, calling it a game of the mind that is accessible to people of all ages and physical abilities. Dykstra began playing at 3 or 4 years old and participated in the chess club at Fairview Elementary School. For her senior project at KU, she organized a summer chess camp for children in grades one through eight.

Dykstra has been running the tournament since 2015 with support from her father, KU health teacher Marvin Dykstra. Both father and daughter coach elementary players at Triad and in the after-school programs at Conger, Roosevelt, Pelican and Mills elementary schools.

I want to keep excitement for the game going in Klamath for my niece and nephew and for my own kids, said Ciara Dykstra, who has a 3-year-old son.

Dykstra requests that parents stay to help with supervision and that players bring quiet games and snacks for between rounds. Adults and players in grades nine through 12 are asked to bring tournament-sized chess boards and clocks.
