CHESS

Scotch on the rocks

Raymond Keene

The Scotch Game, certainly as far as world championship play is concerned, languished unused for around a century until Kasparov unexpectedly revived it against Karpov in two games from Lyons in their most recent contest. Doubtless it will now become all the rage, and as evidence of this I shall presently cite a win by Timman with it from his Candidates match against Robert Hiibner.

In common with many other commenta- tors I had believed that the Scotch derived its name from a correspondence game between Edinburgh (as White) and Lon- don (Black) played between 1826 and 1828. That game began 1 e4 e5 2 Nf3 Nc6 3 d4 Nxd4 4 Nxd4 exd4 5 Qxd4 Ne7 6 Bc4 Nc6 7 Qd5 and was won brilliantly by White in 60 moves. What I had not appreciated was that there had been an earlier game, London (White) against Edinburgh (Black), played by correspond- ence between 1824 and 1825, in which the Scotch concept of 3 d4 was introduced for the first time. What the canny Scots realised was that White need not make a gambit of the opening after Black captures on d4. White can simply recapture, main- taining material parity and a slightly freer position.

Here are the moves of the London- Edinburgh game from 1824, which should perhaps give pause for thought as to the correct naming of the opening.

Kg8 (Diagram) White's rook sacrifice is quite wrong. He should play 27 Re7 Qh5 28 f7+ Rxf7 29 Qd4 Kf8 30 Rel. Alternatively 27 Re7 Qg6 28 Qxc7 Rxe7 (if 28 . . Re8 29 Qe5 Bf7 30 Qxb5) 29 fxe7 Re8 30 Qe5 Qh7 31 Qf6 Bf7 32 h3 and Black is totally paralysed. After the rook sacri- fice Black escapes, since on move 30 his king can run to g8 rather than e8 which the White players had completely overlooked in their calculations. 27 Rxg5+ hxg5 28 QxgS+ Kf8 29 Bd4 Be6 30 Qc5+ Kg8 31 Qg5+ Kf8 Now White should take a draw with 32 Qc5+. 32 Bc5+ Ke8 33 Qd5 Ra6 34 Qb7 Qh5 35 f7+ Kxf7 36 Rfl + Kg6 37 Qe4+ Bf5 38 Qe8+ Rf7 39 Qg8+ Kf6 40 g4 Ra8 41 QxaS Qxg4+ 42 Khl Rd7 43 Ba3 Kf7 44 Qc6 Rdl 45 Qxb5 Qe4+ 46 Kgl Kg6 47 Qb2 Qg4+ 48 Qg2 Qxg2+ 49 Kxg2 Bh3+ 50 Kxh3 Rxfl 51 Bel a4 52 a3 Rf5 White resigns.

Much stronger than 11 0-0. White gains space, pushes back Black's pieces and intro- duces his rook into the game in an unusual way. 11 . . . Re8 12 h5 Nf8 13 Rh4 c6 14 Na4 Qd4 This looks like a good idea, as Black prepares to transfer his queen to the other side of the board. However, paradoxically, the queen will be even more exposed there. 15 Nxc5 QxcS 15 . . . Qxdl + 16 Bxdl dxc5 leaves Black without prospects. 16 Nc4 Rd8 17 Be3 Qb5 18 a4 Not 18
