Central control

In chess the tactics may change but the strategic fundamental principles are always the same, so that Chess Fundamentals is as good now as it was thirteen years ago.

Jos Ral Capablanca

Control of the centre has been considered to be the heart of chess strategy from time immemorial. But as the Cuban World Champion has pointed out, the fundamentals remain the same, though application may change in the course of time. Above I quote Capa from the 1934 edition of his Chess Fundamentals.

When Chess Fundamentals was released for the first time in 1921, the hypermodern era in chess had not flourished in full flow, whereas thirteen years later it had a great number of adherents: Reti, Nimzowitsch, Tartakower to name a few, and not to be left behind were the world champions Alekhine and Capa himself!

The hypermodernists, as they liked to call themselves, came up with the idea that centre control need not be achieved only by pawn occupation of central squares, but can equally be done from pieces controlling the centre from flanks.

Coming back to the Cuban genius comment, the fundamental principle of central control is all-inclusive and gives one room for improvement as and when the situation arises. This is a typical feature in any artistic endeavour.

While taking a look at a recent game of Indian super talent Arjun Erigasi, these thoughts about central control by various means were sparked. What if a flank pawn was given up in return for a central one in ordered to acquire control of central squares? Surely this must be a method envisioned by hypermodernists, right?

This is a position from the game Erigasi versus Aronian from the Goldmoney Asian Rapid 2021. This is a normal-looking position in a hanging-pawn structure. Here Erigasi continued with...

16.b4!

...which sparked added interest into a position with dynamic equilibrium. This is a real sacrifice of a pawn, which cannot be regained by any forced sequence of moves. So, what is the logic behind such a venture?

White wants to secure the central d4 square firmly in his control for occupation of his dark-squared bishop. The opened c-file can be a factor later on in the game. In the shorter run, White gains a few tempi with which he can build upon his initiative on the kingside. Of course, he also runs the risk of remaining a pawn down for the whole course of the game against none other than Aronian.

And bearing in mind that this was a rapid game, the intuitive decision is even more commendable!

16...cxb4 17.Bd4 Qd8 18.Rc1 Bb7 19.Qf3 Qd6

In the last few moves White has gained a few tempi to bring his pieces into the striking zone of Blacks kingside. He continued amassing more forces with

20.h4!?

However, at this moment White had a veiled tactical opportunity by means of 20.Nf5!? gxf5 21.Bc5! Qxc5 22.Rxc5 Bxc5 23.Qg3 check, followed by 24.Qc7 winning material similarly to the Lasker-Bauer theme using a double attack. But Black can avoid this with 21...Qd8 22.Bxe7 Qxe7 23.Qg3+ Kh8 24.Rc7! with another double attack. Black can survive, though, with 24...Ne4! and the game goes on.

20...Rfc8 21.h5 a5 and now White continued with

22.Bf5!

Not a difficult tactic based on overload, but nevertheless a pretty one! Of course, Black cannot recapture with 22...gxf5 because of 23.Nxf5 and Blacks queen is powerless to stop either a deadly check on g3, or defend his bishop on e7. The game continued with

22....Rxc1 23.Rxc1 Ne8?!

Perhaps it is here that Black starts drifting. Maybe Black could try to contest the c-file via the sixth rank with 23...Ra6!? and I have a feeling White has positional compensation for the pawn deficit, but this is debatable!

24.Qg4

White has slowly but surely moved his pieces near the striking zone, and Black falters, falling prey to a cute though not a standard tactic. Black continued with

24...Ng7?

Black apparently can still hold his fort with 24...Nf6 25. hxg6!? hxg6 26.Qg5 Nh7! which shows that the position is still in equilibrium, though the character of the game has been widely transformed! What William Cluley postulated in the 1850s still remains true: Chess is a game of equilibrium.

25.Bxg6?!

White was alert to win a pawn using a double attack. However if he had chosen the right order of moves, e.g. 25.Bxg7! Kxg7 26.Bxg6 Blacks position is due to collapse surprisingly quickly. But since this was a rapid game, one is not warranted to criticise a players decisions with an eagles eye.

25...fxg6 26.Bxg7 Rc8!

This is the difference compared to the variation 25.Bxg7, as Black is not forced to recapture.

Master Class Vol.4: Jos Ral Capablanca

He was a child prodigy and he is surrounded by legends. In his best times he was considered to be unbeatable and by many he was reckoned to be the greatest chess talent of all time: Jose Raul Capablanca, born 1888 in Havana.

However, from a practical point of view, White has regained his lost material and Blacks king lacks a proper pawn cover. When short of time, this usually tilts the balance in favour of the attacker, which happened after further interesting moments, when Erigasi Arjun was able to crown his highly creative play with a well-deserved victory.

This is the position after Whites sixth move from the game Sargissian-Bok from the European Team Championship 2017.

Here the Armenian Grandmaster continued...

7.b4!?

...with an idea, in spirit, similar to the game we have discussed earlier. White embarks on this flank pawn thrust/sacrifice in order to secure the complete control of the central d4-square. He also opens the c-file in the process and gains a few tempi for maximising his development.

7...cxb4 8.Bb2

It is important to note that White also stops Blacks normal development as he has to waste a further move in protecting his g-pawn before moving his dark-squared bishop, which would in turn delay his castling. Such factors also come into account while observing the pawn sacrifice.

8....Nc6 9.Rc1 a6?!

I have a feeling that Blacks position does not warrant such a luxury as to make a pawn move on the queenside in order to stop Bb5.

10.Nd4 Nxd4 11.Bxd4

I love this position: the bishop on d4 is super powerful. He also threatens to bring his other bishop to a dominating diagonal with Bd3 on the next move.

11...Bf5 12.Be2 Qd7 13.Qb3

By putting pressure on d5, White stalls any freeing ideas associated with Rc8 etc.

13...Be6 14.0-0 f6 15.Bh5+ Bf7 16.Bxf7+ Kxf7?!

Surely better was 16...Qxf7, and now perhaps 17.a3!? is worth considering as to meet 17...bxa3 with 18.Qb6!?

17.Bb6 Be7 18.Rc7

White has made full use of the gambit. He has captured the c-file and entered the seventh Rank. Black's King remains dodgy on f7 and Black's pawns are falling one after the other soon.

18...Qd6 19.Rfc1 Rhe8 20.Ba5

White regained material with interest and soon enough won the game.

The next game we are going to deal with is one by the enigmatic genius Sultan Khan. How can I not include this example! In his game against Stahlberg from the Prague Olympiad in 1931, things have clearly gone wrong for the British Champion. He has wasted tempi in the opening, is on the verge of losing his bishop pair to Whites a3 and his knights on e7 and g8 have trouble even breathing.

Here he came with the spectacular wing gambit, which is the theme of our study. His excellent feel for squares and the statics of a position shine with clarity. Readers would of course know of his excellent win against Capa in a Queens Indian with a2-a3, which was a deep move to indirectly control the centre. The system which is currently named after Petrosian was first used by Mir Sultan Khan to indirectly control the e4-square by preventing Bb4.

He continued in the above position with

9....b5!

At the cost of one pawn, Black strives to stay in the game and not get run over immediately. He gains control of the d5-square, which is of paramount importance to complete his development. Only if one of the knights can come to d5 can the other go to e7 and the king can castle to safety. Without a doubt, this is Blacks best chance of a defence, and one that aesthetically looks good as well!

10.cxb5 Nd5 11.0-0 Nge7 12. a3 Ba5 13. Bg5 h6 14.Bxe7 Nxe7 15.Be4 c6!

The audacity of the move is stunning! Black wants to preserve his light-squared bishop, even at the cost of making his pawn structure more ugly. But he opens lines and creates more freedom for his pieces. Whites advantage remains, but Black is changing the character of the game and making a fight out of what he has within his means.

16.bxc6 dxc6!?

Sultan still wants to preserve his light-squared bishop. He absolutely knew no prejudice with regard to so called 'correct play' as he was completely self-taught like a future day Alpha Zero!

17.Na4 0-0 18.Nc5 Rb8 19.b4 Bb6

Whites advantage still very much remains, as both sides have not committed any sort of errors. But the nature of play has become different. Black fought and drew this game at the end! This is indeed creditable against such a formidable player as Gideon Stahlberg. White further won another pawn by playing

20.Nxb7 Rxb7 21.b5

I wonder if Sultan himself would have traded quality for the prospect of winning a pawn. The fact that Whites advantage remains just as before and only got transformed is an unshakable truth as is with energy in this universe!

Nevertheless, at a later point, White committed errors at the face of stiff and original resistance from the master craftsman wielding the black pieces. At the end, Black drew the game being one pawn down in an opposite-coloured bishop position. One can only wonder at the foresight of Sultan Khan at vehemently refusing to exchange his light-squared bishop for his opponents counterpart. Of course, it is not correct to reason out an artists masterpiece: its just there to be enjoyed. The rest of the game is a wonderful example of the beauty of staying in the moment, which Sultan did really well.
