pawn majority. If 40...c6, White exchanges twice on c6, then plays e4 when he wins the king and pawn ending as Black’s king must move over to the kingside and leave his queenside pawns to the white king. 41 Rg1 c6 42 g4! fxg4+ 42...cxd5 43 gxf5 Re7 44 h6! gxh6 45 Rh1 and White is effectively a pawn ahead due to Black’s doubled d-pawn. 43 Rxg4 Re7 44 dxc6+ Kxc6 45 e4 d5 Black is gradually over-stretching. 46 e5 b5 47 Rg2 Kc5 48 Ke3 Rf7 49 a3 b4 50 Rc2+ Kb6 51 axb4 axb4 52 Rc8 Neither of Black’s pieces can play an effective part in the game. Now it only needs White’s king to join in and the game is effectively over. 52...Rf5 53 Kd4! Rxh5 54 e6 1–0 Clarke was known as a quiet positional player, but a man of his class could produce a big attack when the opportunity arose, as our final game shows. White: Peter Clarke Black: George Wheeler WECU Championship, Winchester, K K 1981 1 d4 f5 2 Nf3 Nf6 3 g3 e6 4 Bg2 Be7 5 0–0 0–0 6 b3 d6 7 c4 Qe8 8 Nc3 Nbd7 9 Bb2 c6 10 b4 d5 11 c5 Ne4 12 Ne5 Nxc3 13 Bxc3 Nxe5 14 dxe5 b6!? 15 cxb6 axb6 16 b5 cxb5 17 Bxd5 Exploiting the weakening of the long diagonal caused by Black’s 14th move. But Wheeler coiuld have ignored this and played 17...Ra3 18 Bb3 Bc5, with a slight edge as White’s kingside is weakened. Wheeler decides to capture the bishop - a deliberate exchange sacrifice - knowing that he gets good chances against White’s king with the disappearance of the lightsquared bishop. 17...exd5!? 18 Qxd5+ Qf7 19 Qxa8 Bc5 20 Rfd1! Black was threatening 20...Bb7 21 Qa7 Ra8 winning the queen. This move is directed against that possibility. Now Black could play to exploit the weakness of the f2 square by ...f4!, which gives him good counterplay. 20...Bb7? 21 e6! Qe7 22 Qxb7! Qxb7 23 Rd7 Qxd7 24 exd7 g6? Both 24...Rb8 and 24...Rd8 would lengthen resistance. 25 Bf6! 1–0 K K K How to win lots of attractive short games Dave LM A few years ago, I discovered that I had played an unusually large number of attractive miniature chess games (usually defined as being of 25 moves or less) and decided that I would work out the common factors that may have led to their short length. In CHESS magazine I published a count-down of the top ten factors, in terms of those which appeared most in my list of attractive short games, each with an illustrative game of my own. That countdown went as follows: 10 Play on the opponent’s greed – setting traps to exploit it 9 Remember the standard sacrifices – an advertisement for Essential Chess Sacrifices! 9
