CHESS

Thoroughly modern Xavielly

Raymond Keene

The phrase 'Hypermodern Chess' often Crops up in annotations and it is worth explaining what this means. In brief, hypermodernism was a movement in chess thought which peaked during the 1920s. It was led by grandmasters such as Alekhine, Nimzowitsch, Rai, Tartakower, Griinfeld and Breyer, and it more or less paralleled the advent of Dada or surrealism in art or, indeed, the atonal musical system of Schoenberg. The essence of hypermodern- isn't was that bishops were to be developed on the flank, in fianchetto (on g2, b2, b7 or g7). Further, that the central pawns could be held back without lessening one's influ- ence on the important central zone. Final- ly, that it was permissible to accept a weakness in one's own camp provided that it led to an increase in dynamism. All this came as a reaction against the classical chess of players like Dr Tarrasch, Karl Schlechter and even Capablanca him- self when he was playing in mechanical mode. This had led to rather too many sterile games. The bible of hypermodern chess was Nimzowitsch's My System, but it Was the Franco-Polish grandmaster, Dr Xavielly Tartakower, who documented the entire movement and its intellectual roots in his massive tome Die Hypermoderne Schachpartie. Here are two games by leading exponents of hypermodernism Which demonstrate the principles they espoused.

Reti — Breyer: Berlin 1920; Sicilian Dragon. I e4 e5 2 NO Nc6 3 d4 cxd4 4 Nxd4 g6 5 Nc3 Bg7 t Be3(16 7 Be2 Nf6 8 0-0 h5 This is typical of reyer's unorthodox approach. Whereas Black y;ould normally play 8 . . . 0-0 Breyer decides; ,..1 true Hypermodern fashion, to undermine White's central installations with a manoeuvre on the extreme flank. The correct answer to this his h3 followed by 10 f4. Reti's reply weakens position and justifies Black's manoeuvre. 9 f3 h4 in „ - Qd2 Nh5 11 Nd5 e6 12 Nc3 Ng3 A shock.

Nevertheless, Black has sufficient resources against this so it would have been more sensible to play the immediate 16 Qxd6 Oxd6 17 Rxd6 when Black's two bishops compensate him for the lost pawn. 16 . . . e5 17 Bc5 Ba6! The key resource which Reti had overlooked or underestimated. If now 18 Qxd6 White will lose the knight on e2 or 18 Bxd6 Qb6+ 19 Kfl 0 0 0 when White is in all sorts of trouble on both sides of the board. Having been surprised by Black's 17th move White goes into a full retreat and the dominant factor becomes White's shattered kingside, which has been wrecked by the bold advance of the black 'h' pawn. 18 Be3 hxg2 19 Ng3 Qh4 20 Qxg2 d5 21 Nfl? d4 22 Bf2 Qf6 23 c3 In his wretched condition White resolves to sacrifice the exchange for a modicum of counterplay. 23 . . .

Appel — Tartakower: Lodz 1938; Tartakower Defence.

1 NO Nf6 2 c4 d6 3 d4 Bg4 It has always struck me as unfair that so many of the hypermodern grandmasters, apart from Tartakower, have an opening or defence named after them. Thus, there is Reti's Opening 1 Nf3, Alekhine's Defence 1 e4 Nf6, the Grunfeld Defence 1 d4 Nf6 2 c4 g6 3 Nc3 d5 and the Nimzowitsch- Indian 1 d4 Nf6 2 c4 e6 3 Nc3 Bb4. The variation employed by Tartakower in this game is as hypermodern as any of those I have just mentioned. There is no doubt that Tartakower was its inventor and that he practised it fre- quently and with great success, Keres and Schlechter numbering amongst his victims. I therefore propose that henceforth this variation should properly be known as the Tartakower Defence. 4 Qb3 Bxf3 5 gxf3 Or 5 Qxf3 Nc6 6 d5 Ne5 7 Qb3 Qc8 Schlechter — Tartakower,

Black now proceeds to build up a decisive attack against the white king under the shelter of his central pawn triangle. 20 c5 Ng4 21 Nd3 Qe7 22 h3 Nxe3 23 fxe3 Qh4 24 Rfl Kh8 25 Qdl g5 26 Qel Qh6 27 Kh2 g4 28 Rhl Rg8 29 Kgl Position after 29 Kg1 (Diagram) 29 . . .

The hypermoderns, with their openings designed to lure on and expose their opponent's central pawns to later counter- attack, may have thought that they had discovered the ultimate El Dorado of chess truth and wisdom. Nevertheless, we now know that both the. hypermoderns and the classicists, with their brutal occupation of the centre and direct development of their bishops on solid central squares such as f4, c4, b5 and g5 can lay equal claim to the final verities in chess. Kasparov's style, for example, the most effective ever seen, is a pleasing blend of both the classical and the hypermodern.
