Chess: How playing bad moves can win games

I HAVE said it before and I shall, no doubt, say it again: it is bad moves that win games. The main reason for this is that bad moves unbalance the position and create the pre-conditions for mistakes to be made. Good moves tend to retain equilibrium and prompt good moves in reply. Playing well simply makes life too easy for one's opponent. Take the following, from the Hudson International tournament in New York.

The opening was a curious variation of the Grunfeld Defence in which White surrenders the bishop pair in order to dislodge Black's king. The standard continuation is 10. Qf4 Bf6 11. h4, but this is not thought to lead to anything special for White. Alex Shabalov, one of the many ex-Soviet grandmasters now playing in the United States, chose a quieter plan, hoping for a later attack. His chance came at move 28.

I am not convinced that 28. Ng4]? is a good move. The double threat of Rxe8 and Qh6+ won him the exchange, but after Black's 30 . . . Qxb2 Black has a good pawn and a nice bishop pair. Had he played 31 . . . Qxa3, the issue would have been in great doubt.

Instead, Hellers, a Swedish grandmaster, played for safety with 31 . . . Bd7 trying to shift the rook from his back rank, but Shabalov produced a wonderful refutation. After 32. h5] Bxe8 33. h6+, White follows with 34. Qxf6, with a winning attack. As the game went, 33. Rh8] gave the kamikaze rook its desire. With Black's king never able to move to f8 without losing his knight to Qc5+, the resulting White attack was decisive.

At the end, Black had no defence to the threat of Qg6 mate.
