Chess vs football: The vital distinction in restriction strategy – Spectator.co.uk

Nearly a month ago, I called for an urgent24-day full national lockdown, arguing that therestrictions were unlikely to make a significant difference in reducing transmission. If we had acted strongly and decisively then, and implemented a circuit-breakerlockdown as we now know that the government's scientific advisory group Sagealso wanted we would be in a much stronger position today.

Many readers considered it a controversial and unwise strategy. The government agreed, declining Sage's advice and instead announcing the eventual rollout of a three-tier system covering areas of medium, high and very high risk, each with their ownrestrictions. Yet case rates, hospitalisations and deaths continue to increase across the country.

This prompted Sir Keir Starmer to finally call for a national two to three weekcircuit break. The Labour leader hascorrectly recognised that the current mixture of restrictions and pseudo-mini-lockdowns which have no clear end or exit-strategy are likely to yield an even greater negative economic impact than a national, brief and finite circuit break after which we could fully reopen the economy.

So why isnt the governments strategy working? After all, the central premise of the restrictions makes sense: if we reduce peoples contact with others in areas of particularly high prevalence, then the virus will struggle to infect new hosts.

It has failed because this isnt a chess game. People arent pawns that can be moved about without ever objecting to whatever strategy the player is employing in each move. Managing pandemics is instead much more like managing a football team. You can have the best players who in theory should always win you the game, but football, like epidemic management, isnt as simple as that.

What is needed in epidemics, like in a successful football team, is collective harmony. The majority of people need to be on board with a particular strategy. This will depend on them clearly understanding whats required of them, that everyone else is putting in a fair and equal effort and, crucially, a belief that their collective adherence to the strategy will make a significant difference. This is what happened during the first lockdown in March and why it was so strongly adhered to.

These principles align with what we know about health behaviour science, an important toolkit that I believe the government has crucially failed to effectively leverage. Most health behavioural models emphasise the importance of motivation. Simply put, if people are motivated enough, they will at least try to adhere to actions designed to protect their health. Behavioural science also highlights how fragile motivation can be and how perception underpins it.

It is clear that today we do not, as a nation, have collective harmony or motivation. This is because of many factors but an important one is perception. Many people simply do not perceive the governments restrictions as making sense because, frankly, many of them do not. Consider those people living under the very high tier whose motivation is likely to be particularly fragile given the sacrifices they are being asked to make.

To protect their motivation to adhere, these people will need clarity on why their particular area is classified as very high while a neighbouring area is not. They will question why their local gyms are closed but restaurants can remain open. Some will question whether a local lockdown is really a lockdown when schools and some workplaces remain open. Many will also question why we are making such sacrifices for a virus perceived to be of little threat to public health. Crucially, they will question the overall strategy as well as askingwhen this will all endand what happens after the second wave is over.

This is why a finite, national and even approach is much more likely to be effective than a fragmented locally targeted one. A collective national approachwill mean people are much more likely to perceive the measures as fair. With just one set of clear rules, the confusion over different restrictions for neighbouringareas will be eliminated and there will be unified clarity on what is expected. Most importantly, there will be a sense of optimism given that a circuit breaker has a finite end followed by thefull re-opening the economy.

The post-second wave strategy should also be made clear now. People need to know what the government is planning for the long-term. It should be made clear that case rates are likely to increase again but that they will do so at a much slower rate. This should allowour weapons widespread testing and track and trace to increase their effectiveness. And when the second wave does indeed pass, the government must value the expert advice of Sage including their health behaviour scientists and stop viewing the public as willing pawns in a game of chess.

Asian Online Team Chess: India finishes 6th in preliminary round, qualifies for quarterfinals – The Indian Express

By: PTI | Chennai | October 18, 2020 10:31:59 pm(Representational Image)

Indian men on Sunday qualified for the quarterfinals of the Asian Online Nations (Regions) Cup Team Championship after finishing sixth in the Swiss system preliminary round.

The top-seeded Indians endured a day of mixed fortunes, winning one match, losing one and drawing the other. They face Mongolia in the last eight stage on October 23.

Starting the day with a 1.5-2.5 loss at the hands of the Philippines in the seventh round, the team led by Surya Sekhar Ganguly bounced back to outclass Bangladesh 3.5-0.5 in round eight before settling for a thrilling 2-2 draw against Australia.

In the match against Australia, the 16-year-old Nihal Sarin provided the crucial win, beating Termur Kuybokarov after B Adhiban had lost to Anton Smirnov. S P Sethuraman and K Sasikiran drew their games.

In the eighth round, Adhiban, Ganguly and Sasikiran posted victories while Sethuraman was held to a draw by Reffat Bin-Sattar.

The fourth-seeded Philippines team had pulled off a 2.5-1.5 win over India in the seventh round with Reglio Barcenilia putting it across Ganguly while Sarin, Sethuraman and Sasikiran drew their games.

Sasikiran was the best performer for India, winning eight of his nine games while Sarin won four of his five and Ganguly five out of the seven he played.

Iran finished on top of the heap at the conclusion of the preliminaries with 15 Match Points (2 MPs for a win, 1 for a draw) followed by Philippines and Mongolia.

When 3 is greater than 5 – Chessbase News

10/18/2020 Star columnist Jon Speelman explores the exchange sacrifice. Speelman shares five illustrative examples to explain in which conditions giving up a rook for a minor piece is a good trade. As a general rule and in fact (almost all?) of the time you need other pieces on the board for an exchange sacrifice to work. | Pictured: Mikhail Tal and Tigran Petrosian following a post-mortem analysis at the 1961 European Team Championship in Oberhausen | Photo: Gerhard Hund

[Note that Jon Speelman also looks at the content of the article in video format, here embedded at the end of the article.]

During the Norway tournament, I streamed commentarya couple of times myself at twitch.tv/jonspeelman, but mainly listened to the official commentaryby Vladimir Kramnik and Judit Polgar.

Both were very interesting, and Kramnik in particular has a chess aesthetic which I very much like. In his prime a powerhouse positional player with superb endgame technique, he started life much more tactically and his instinct is to sacrifice for the initiative whenever possible, especially the exchange: an approach which, after defence seemed to triumph under traditional chess engines, has been given a new lease of life by Alpha Zero.

So I thought today that Id look at some nice exchange sacrifices, but first a moment from Norway where I was actually a tad disappointed by a winning sacrifice.

At the end of a beautiful positional game, which has been annotated here in Game of the Week, Carlsen finished off with the powerful

42.Re8!

and after

42...Qxe8 43.Qh6+ Kg8 44.Qxg6+ Kh8 45.Nf6

Tari resigned

Of course, I would have played Re8 myself in a game if Id seen it, but I was hoping from an aesthetic perspective that Carlsen would complete this real masterclass and masterpiece with a nice zugzwang.

You start with c4 to prevent 42.f3 c4, creating some very slight confusion and then it goes:

42.c4 Kg8 43.f3

And for example: 43...Qd7 44.Qh6 Qe6 45.Kg3 fxe4 (45...Rg7 46.Nf6+ Kf7 47.Qh8 Qe7 48.Kg2) 46.dxe4 Rf4 47.Nxf4 exf4+ 48.Kxf4 Qf7+ 49.Kg3 Qg7 50.Qxg7+ Kxg7 51.Rxf8

Black can also try43...Rh7

and here after 44.Rxf8+ Kg7

as the engine pointed out to me, its best to use the Re8 trick:

45.Qxh7+! (45.Rf6 is much messier) 45...Kxh7 46.Re8!

The black queen is trapped.

For todays examples I used my memory and the ChessBase search mask when I couldnt track down a game exactly. For instance,for the first one byBotvinnik [pictured], I set him as Black with 0-1, disabled ignoring colours, and put Rd4 e5 c5 on the board which turned out to identify the single game I wanted a hole in 1!I also asked my stream on Thursday for any examples, and one of my stalwarts, a Scottish Frenchman, found me Reshevsky v Petrosian (I couldnt remember offhand who Petrosians opponent was) and drew my attention to the beautiful double exchange sacrifice by Erwin L'Ami from Wijk aan Zee B.

Before the games themselves, which are in chronological order,it might be worthwhile to consider what makes an exchange sacrifice successful. Whole books have been written on this and Im certainly not going to be able to go into serious detail. But a couple of points:

The need for extra pieces applies particularly to endgames. For instance,this diagram should definitely be lost for Black:

Its far from trivial, but as a general schema the white king should be able to advance right into Blacks guts and then White can do things with his pawns. Something like get Ke7 and Rf6, then g4 exchanging pawns if Black has played ...h5. Play f5, move the rook, play f6+, and arrange to play Rxf7.

But if you add a pair of rooks then it becomes enormously difficult. And indeed I really dont know whether God would beat God.

The Queens Gambit Tries a Risky Play: Betting Chess Can Be Good TV – The New York Times

The Queens Gambit includes more than 300 games, some glimpsed only in the foreground or background. To keep each match and each tournament from blending entirely into the next, the production designer, Uli Hanisch, developed unique color palettes to distinguish one locale from another. Steven Meizler, the cinematographer, varied the angles. The sounds the pieces make against the board change, as do the rhythms from allegro to adagio.

No traditional match plays out fully from start to finish. (A few speed chess sequences come close.) Typically, the camera captures only a few moves. Novice viewers rely on sportscasters or whispers among the audience or the gestures of the characters drummed fingers, blinked eyes, pursed lips to understand the dynamics and stakes.

For Beth, abandoned first by her birth parents and then by her adoptive family, the stakes tower. Only while playing does she feel a sense of purpose and belonging. In a later episode, Beth overhears some Russian champs discussing her. Shes like us, a grandmaster says. Losing is not an option for her. (This was dialogue Kasparov suggested.)

Beth struggles with her addictions, believing that tranquilizers enhance her play. The accuracy that defines the chess scenes perhaps falters here could someone play excellent chess while doped? I cant tell you Ive ever heard of a chess player performing on Valium, said Jennifer Shahade, a two-time United States Womens Champion.

Pandolfinis response: This is entertainment.

Whether a woman could play this well ever, on or off tranquilizers, has been a source of debate since the novel was released. One Times reviewer wondered whether women had the extreme aggressiveness required. Another doubted that women lacked the physical stamina. Those views didnt end in 1983.

At chess camp, Shahade remembered, a visiting lecturer told the girls that women lacked the I.Q. Shahade sees the lack of great women players as more of a social one: Women dont see other women playing so they dont take up the game themselves.

Chess and bees – TheArticle

The Howard Staunton Memorial Chess tournaments were staged for several years at Simpsons-in-the-Strand, the traditional home of British Chess. At one of these august events, Professor Michael Crawford, in his persona as Director of The Institute for Brain Chemistry and Human Nutrition, based at Londons Imperial College, delivered an opening speech, and one deliberately aimed at the players in the event.His point was that the consumption of marine based nutrition was beneficial for the brain.

Listening in the audience was the Grandmaster Nigel Short, Britains only challenger for the World Chess Title in the 20th century. Emulating Sherlock Holmes and Dr. Watson after the successful denouement of the short story,The Dying Detective, Nigel went to Simpsons dining room for something nutritious a giant Dover sole. Nigel persevered with his piscatorial, brain-enhancing diet throughout the competition and duly turned in a superb performance.

Professor Crawford does not just confine his dietary advice to fish and related aquatic delicacies. He is also a keen apiarist and advocate for the health benefits of honey, in particular raw honey, that retains the vital pollen, which the EU would so like to remove. In his guise as a beekeeper, Professor Crawford has now challenged me to write a column forTheArticle, linking bees and chess.

The solution to this conundrum is, in fact, relatively simple, in that both bees and chess have famously been invoked as models for exemplary social structures. There is a vase by Exekias in The Vatican Museum, as indeed another in The British Museum, which depicts the heroic warriors Ajax and Achilles absorbed in a board game, one of the hallmarks of a civilised society, during the siege of Troy.

The game involved was almost certainly not chess, but Achilles himself definitely figures in Homers use of bees to delineate the harmonious running of society. In his bee similes, Homer underscores the reciprocal dependencyof the collective, the individual, and the household, extolling unity within diversity. Homer describes the Greeks gathering for a council of war, writing in hisIliadcirca 700 BC, and , in this instance, they resemble a cloud of bees:

as when offrequentbeesSwarms rise outof a hollow rock, repairing the degreesOf their egression endlessly,with ever rising newFrom forth their sweet nest;as their store, still as it faded, grew,And never would cease sending forthher clusters to the spring,They still crowd out so(HomersIliad, Book II, lines 87-93. Translated by George Chapman, first published in 1598).

This simile emphasises the unity of the individuals who make up the Greek army, illustrating the ideal dynamic, in which neither the interests of the individual, nor those of the collective, take excessive precedence. According to Homer, a fully functioning society will, therefore, maintain a balance between unity and diversity.

Yet they,as yellow wasps, or bees(that having made their nestThe gasping cranny of a hill)when for a hunters feastHunters come hot and hungry in,and dig for honeycombs,Then fly upon them, strike and sting,and from their hollow homesWill not be beaten, but defendtheir labours fruit, and brood;No more will these be from their port,but either lose their blood(Iliad, Book XII, lines 167-170).

Thus,each Greek warrior is actually promoting his own personal interests, whenever he defends the collective. It is at the tipping point where individuality exceeds its bounds and proper discipline is abandoned, that disaster strikes, as when Achilles sulks in his tent and his soul mate, Patroclus, is inadvertently slain, by the Trojan hero, Hector.

Shakespeare encapsulates this problem in his tragedyTroilus and Cressida, when the wily Odysseus (identified by his Latin name Ulysses in the play) explains that order, or degree, has broken down: Take but degree away, untune that string, and hark, what discord follows!

Bee similes also figure prominently in VirgilsAeneid, appearing first in Book I, then in Book VI, and finally in Book XII. Their studious arrangement suggests that, like Homer, Virgil regarded bees as significant, in order to fully comprehend hisentire magnum opus. Indeed, Virgils other works support this inference, because they prove that Virgil considered bees toexemplify a well-organised, homogenous, and dutifully obedient society.

In his poemGeorgics(Book IV) Virgil discusses bees and their habits at length, using bees as a paradigm for his vision of the perfect society: a hardworking, patriotic, thrifty, disciplined community, all striving towards a single, noble end. Each of the four references to bees in theAeneidprovides an insight into this model community, especially emphasising the collective, renascence, and the future foundation of Rome itself.

In Virgils time (writing in the late 1st century BC), it was still believed, following Aristotles lead, that the hive was ruled by a king bee (rather than a queen) which makes the deployment of the bee simile/metaphor of precise relevance in the transition period between the Roman Republic and the Roman Empire. In fact, it was not until 1609, with Charles ButlersThe Feminine Monarchy,that the Queen was correctly identified, not so much as a leader, more as afons et origoof the hive.

Such is their toil, and such their busy pains,As exercise the bees in flowry plains,When winter past, and summer scarce begun,Invites them forth to labor in the sun;Some lead their youth abroad, while some condenseTheir liquid store, and some in cells dispense;Some at the gate stand ready to receiveThe golden burthen, and their friends relieve;All with united force, combine to driveThe lazy drones from the laborious hive:With envy stung, they view each others deeds;The fragrant work with diligence proceeds.(VirgilsAeneid, Book I, lines 430-436.Translated by John Dryden and first published in 1697.)

Virgils bees are not a clustering swarm, like Homers, but a homogenous mass, divided only by their varying tasks, which they perform faithfully and mechanically. Such a devoted and focused society, in Virgils mind, represents the ideal human template forcivilisation. The poet illustrates the importance of the collective, but dismisses individuality altogether, a shift that distinguishes him from Homer. It is easy to see the direction in which the poet is leading us.

In sharp contradistinction to the poet Ovid, who was banished by the Emperor Augustus far from Rome to Tomi on the Black Sea, Virgil is composing state-sanctioned, if subtly disguised, propaganda, where one emperor and one unified compliant imperium are the order of the day.In actual bee society, this is stretching the metaphor, but as a refined political message within human society, it is highly persuasive. It is a feat of legerdemain, not lost on contemporary environmental advocates, to imply that the path to paradise for humans lies in a direction imposed by nature itself. As Alexander Pope put it in hisAn Essay on Man:

All nature is but art, Unknown to thee;All chance, direction which thou canst not see.

Virgil emphasises the paramount importance of society and the need for people to have their appointed place in it, implying that the collective must take precedence over the individual. Roman society was, indeed,highly stratified, and, again, Shakespeare points the way in the opening lines ofJuliusCaesar:

Hence! Home, you idle creatures, get you home. Is this a holiday? What! Know you not. Being mechanical, you ought not walk. Upon a labouring day, without the sign of your profession. Speak, what trade art thou?

Liberal arts or professions in Rome were those practised by free men and included rhetoric, law, politics, poetry, medicine and architecture. Opposed to these were those considered sordid, such as portitor (the boatman or carrier), fenerator (the usurer), while lowest of the low were craftsmen who worked with fire, such as smiths and potters, known as banausic in Greek and mechanical in Latin.

Virgil understands a beehive to be an illustration of human civilisation. Though the individual will pass away, the legacy of the community will endure. Over and over again, the hive is reborn as a new generation of insects rises to take the place of the old one, defying and surviving various crises, such as

Thus, when the swain, within a hollow rock,Invades the bees with suffocating smoke,They run around, or labor on their wings,Disusd to flight, and shoot their sleepy stings;To shun the bitter fumes in vain they try;Black vapors, issuing from the vent, involve the sky.(Aeneid, Book XII, lines 587-592).

This simile introduces a significant, final aspect of Virgils ideal society: the shepherd, or leader of the people.

According to Virgil, the ideal society must have a ruler. Again,GeorgicsBook IV provides an explanation, using the bees devotion to the ruler, which the Romans, as we have seen, interpreted as a king, although due to more modern science we now know to be a queen. The bees labour intensively and selflessly, because of the ruler; but when that ruler eventually expires, the hive degeneratesand the bees annihilate their own work.Likewise, a rulers wise guidance unifies the Apian way and thus preserves the peoples purpose.

It is impossible, once again, to avoid inferring a reference here to the rise of Augustus. In particular, hissoi distant necessaryslaughters of the opposition on his way to the top, such as the proscriptions of the second triumvirate, and the cauterisation of the wounds caused by fanatic republicans, such as Brutus and Cassius.In Virgils vision of the perfect Roman society, such harsh measures are justified, if order and universal peace, the Pax Augusta and the closing of the doors of the temple of Janus, are to be the beneficial outcome.

Now we come to the chess element of the equation, proving unequivocally that chess, in common with bees, has been adapted as a social model, one singularly popular in the late Middle Ages. At that time, chess was already recognised as one of the seven liberal arts, supposedly promulgated by Aristotle, no less, the sage described by Dante as il maestro di Collor che sanno (the Master of the men who know). These were meant to be the common attributes of knights and their ladies, embracing,inter alia, equestrianism, toxology, pugilism andde arte venandi cum avibus(the art of hunting with birds, or in other words falconry).

Around 1300, the northern Italian Dominican Friar, Jacobus de Cessolis published his moralising book about chess,Liber de Moribus hominum et officiis nobilium super ludo scacchorum. Packed with entertaining stories and material ripe for sermons, this book proved inordinately popular, even appearing as the first book ever published in English, in England, by Caxton in the late 1470s,The Game and Playe of the Chesse.

One turns to Cessolis in vain for instruction on how to win at chess, instead the descriptions of the pieces and pawns stratify and reinforce the prevailing social order. Although a hierarchical social model is by no means inherent in the game of chessper se, it is no surprise that such a self-perpetuating template was so popular with kings, dukes and other members of the ruling nobility, whose libraries often contained multiple copies.

The ranks of society, according to the Cessolis template, began with the King and Queen, at the apex,followed by the Alphins, aka bishops or judges, then knights and rooks, or royal messengers, followed by the common people, in other words, the pawns. Indeed, the eight pawns on each side were actually credited separately with their trades, much as in the antique Roman classification mentioned both by Shakespeare and the Lewis & Short Latin dictionary. The trades included labourers, tillers of the earth, drapers and makers of cloth, merchants, money changers, physicians, taverners and the banausic or mechanical trades of smiths and other workers in iron and metal.

The word Alphins (bishops) requires some explanation. The concept still survives in Spanish (Alfil) and Italian (Alfiere) where the L/F sound is more important than the meaning, signifying a reference to the word elephant, the root of which is Aleph Hind, or Indian Ox. Since most Western Europeans would never have seen such a pachyderm, it was the phonetic representation, rather than the meaning, which travelled with the expansion of chess. Traces of Alphin can also be found in other languages, where the word for a chess bishop embracesLe Fou, the jester in French,Loperin Dutch,Luferin German, both meaning runner andLovac(hunter) in Serbo-Croatian. As one journeys further East, however, the modern mammoth reclaims its own, as in the Russian for Bishop,Slonwhichtranslates as the elephant.

The book of Cessolis drew on and strengthened the late mediaeval mind-set that chess was a symbolic representation of society and imparted to that notion much greater force and precision. At one point it was, though still a distant rival, second only to The Bible in terms of popularity, and thus merits its place alongside the bee metaphors of Homer and Virgil, as a genuine attempt to describe an ideal social structure of civilisations which have long since fallen into desuetude.

Fascinating, as it is, to excavate mediaeval views about chess, the modern game still continues apaceand twochess news items of note occurred this past week. The first was the87th birthday ofDr. Jonathan Penrose. He won The British Chess Championship a record ten times and was subsequently awarded the Grandmaster title Emeritus.His doctorate is in Psychology. His brothers areOliver Penrose, as well as prominent author and physicist Professor Sir Roger Penrose, who was honoured with the 2020 Nobel Prize in Physics, for his discovery that black holes are a robust confirmation of Einsteins general theory of relativity.

The second momentous item of note was the first loss by World Champion Magnus Carlsen in classical chess for two years, two months and ten days. Carlsen suffered this rare setback against Jan-Krzyztof Duda last Saturday in Stavanger, Norway, where the first over the board elite event for many months has been taking place, in spite of Covid 19 restrictions. Here is a link to the game, with commentary.Carlsens 125 game unbeaten streak is a World Record and in next weeks article I shall be looking at world records, including Carlsens unbeaten run in chess, as well as two in other sports, which occurred recently, in both tennis and Formula 1.
