1. d4 d5 2. c4 e6 3. Nc3 Be7 4. cxd5 exd5 5. Bf4 { In most of the lines of the Exchange Variation the bishop is deployed at g5, but Black's clever move order has prevented this plan. } 5... Nf6 6. e3 O-O 7. Bd3 c5 { Attacking White's center point at d4. } 8. Nf3 Nc6 9. O-O Bg4 10. dxc5 Bxc5 { Black is saddled with an isolated pawn, but this is only temporary. } 11. h3 Bxf3 12. Qxf3 d4 13. Ne4 { 13.exd4 Bxd4 This position is fine for Black. } 13... Be7 14. Rad1 { A clever move. Now can you see why 14...dxe3 would lose material? } 14... Qa5 { 14...dxe3 15.Nxf6+ Bxf6 16.Bxh7+ Kxh7 17.Rxd8 exf2+ 18.Rxf2 Raxd8 } 15. Ng3 dxe3 16. fxe3 { Karpov has successfully traded away his isolated d-pawn. However, he now faces my bishop pair which is particularly effective in the open position. I can also use the f-file to put pressure on f7. } 16... Qxa2 { The a-pawn is irrelevant. Karpov is looking for the shortest way to e6, where the queen will be well posted for both defense and attack. } 17. Nf5 Qe6 { Karpov defends, but I am about to turn up the heat! } 18. Bh6 { Do you see why 18. ... gxh6 loses quickly for Black? } 18... Ne8 { Black defends the g7-square with the knight, but the kingside has become very congested. My advantage in space is the key to winning the game. 18...Ne5 19.Qxb7 Nxd3 20. Nxg7 Qe4 21.Qc7 Ne5 22.Nf5 with a decisive attack for White. } 19. Qh5 g6 { This fork is harmless. } 20. Qg4 Ne5 { As a general rule, it is a good strategy to exchange off the opponents attackers when you are defending. Karpov is counting on Nxd3 to make his defensive work easier. My next move is forced. } 21. Qg3 { I wanted to win by a direct attack. However, 21. Nxe7 followed by Bxf8 would have sufficed. } 21... Bf6 { 21...Nxd3 22.Nxe7+ Qxe7 23. Bxf8 Kxf8 24.Rxd3 Black does not have enough compensation for the material. } 22. Bb5 { I want to keep my bishop! The rook on f8 is barely worth capturing. } 22... Ng7 23. Bxg7 Bxg7 { Now I don't give up my beautiful steed for the useless bishop. Instead, I bring the rook into the game. To win against a player of Karpov's ability requires the use of the entire army. } 24. Rd6 Qb3 { Now that the queen has been chased away, the knight on e5 is defended only by the bishop, which I now remove from the board. } 25. Nxg7 Qxb5 { Things don't look so bad for Black, because my knight seems to be trapped at g7. 25...Kxg7 26.Qxe5+ } 26. Nf5 { But is isn't! The pin on the g-file provides an escape route. 26.Nh5 Nf3+ 27.Qxf3 Qxh5 28.Qxh5 gxh5 and it is White who would have to play for a draw. } 26... Rad8 27. Rf6 { I don't want to trade, I want to attack! } 27... Rd2 { Black's invasion of the seventh rank is not worrying because I have plenty of defensive resources. } 28. Qg5 { A nasty move which threatens all sorts of discovered attacks on the 5th rank. For example, if Karpov plays 28...d3 I reply 29.Nh6+ and take his queen! } 28... Qxb2 { A great mistake. The king should have retreated into the corner. This was no time to be greedy! } 29. Kh1 { Now Karpov cannot take the pawn at g2 with check. } 29... Kh8 { Even though Black is lost at this point, 30...Rd7 would have put up more resistance. } 30. Nd4 { Now the knight at e5 is undefended, and if it moves to another square, then the pawn at f7 falls. } 30... Rxd4 { A sad necessity. } 31. Qxe5 { Here Black' s time ran out and I was awarded the point. But I was winning anyway. } 31... Rd2 32. Qe7 Rdd8 33. Rxf7 Rxf7 34. Rxf7 { Black cannot defend this position. } 1-0
