[Event "London"] [Site "?"] [Round "0"] [White "Seirawan"] [Black "Karpov"] [Result "1-0"] [ECO "A05"] [Opening "Reti: 1...Nf6"] 1. Nf3 Nf6 2. c4 e6 3. Nc3 d5 4. d4 Be7 5. Bg5 h6 6. Bh4 O-O 7. Rc1 {White avoi ds committing his e-pawn, hoping to find a brighter future for his light-squared bishop on g2.} 7... b6 8. cxd5 Nxd5 9. Nxd5 {Not 9...Bxh4 10 Nxc7. With the pawn structure clarified White intends to put pressure on d5 and c7, while Black hopes to get play on the e-file and possibly break with ... c5.} 9... exd5 10. Bxe7 Qxe7 11. g3 Re8 {Now if 12.Bg2 Black will play 12... Ba6 and gang up on e2, catching White's king in the center.} 12. Rc3 { A multi purpose move. The rook may lead a battery attack on c7 and may also go to e3 to neutralize the pressure on e2.} 12... Na6 {If 12...c5 then 13 dxc5 bxc5 14 Qxd5 Bb7 15 Qb3 and White will consolidate after Re3. Karpov's move covers c5 and c7, and the knight may jump to b4 later.} 13. Qa4 {Very aggressiv e--White attacks both the knight and the rook, but leaves his back rank exposed.} 13... c5 {It isn't clear whether this is a sacrifice or a blunder, but Black seems to get a strong attack for his knight.} 14. Re3 Be6 15. Qxa6 cxd4 16. Rb3 {Preventing checks on b4. It now seems that Black should be able to keep up the pressure on the e-file, but Seirawan consolidates beautifully.} 16... Bf5 17. Bg2 Bc2 18. Nxd4 { Giving back material to kill Black's initiative.} 18... Bxb3 19. Nxb3 Rac8 { Black might try 19...Qb4+, but after 20 Kf1, White will consolidate by 21 Bf3 and 22 Kg2, and Black's pieces will be even more confused than in the game.} 20. Bf3 Rc2 21. O-O Rxb2 {Now Black has got back almost all his material, but his pieces don't work together well, while White will calmly prepare a nasty counterattack.} 22. Rd1 Rd8 23. Nd4 {White's position is a wonderful picture of harmony, while Black is just trying to keep out the flood. Notice how all of Black's light squares are potential targets: b5,c6,f5 and d5.} 23... Rd7 24. Nc6 Qe8 25. Nxa7 {Now White offers a piece sacrifice, but, in contrast to Black's offer on move 13, he has a concrete mating continuation in mind.} 25... Re7 26. a4 Qa8 27. Rxd5 Qxa7 28. Rd8+ Kh7 29. Qd3+ f5 {29...g6 allows 30 Qd4.} 30. Qxf5+ g6 31. Qf6 1-0
