1. e4 e6 2. d4 d5 3. c4 dxe4 4. Nc3 Nf6 5. f3 c5 6. d5 exd5 7. cxd5 exf3 8. Nxf3 Bd6
The famous Keres Variation, which, for some reason, was less popular in the tournament than I had expected.
9. Bg5 O-O 10. Be2 h6
10... Bf5 11. O-O Nbd7 12. Nh4 Bg6 13. Nxg6 fxg6 14. Ne4 Be5 15. Qb3 Qb6 16. Bxf6 gxf6 17. Qxb6 Nxb6 18. Nc3 Rad8 19. Rad1 Kg7 20. Bf3 Nc4 21. Ne4 Bd4+ 22. Kh1 Ne3 0-1, Purdy - Segerberg, DDGA'96.
11. Bh4 g5 12. Bf2
Naturally I had to see if 12. Nxg5 works, but after 12... hxg5 13. Bxg5 Nbd7 14. O-O Bd5 15. Ne4 Qb6, White has very clear advantage. So far, I was most happy with a pawn up and more space.
12... a6 13. O-O b5
This looks easy. Now Black can plan Bb7 or b4 and Nxd5. Probably worse is 13... Qc7 14. h3 g4?! 15. hxg4 Nxg4 =/+.
14. Qc2
14. Qd2 with the idea 15. Nxg5 hxg5 16. Qxg5+ Kh8 17. Bd4! cxd4 18. Rxf6 +-.
14... Nbd7
14... Bb7 15. Qf5 b4 was the alternative, but why rush.
15. Rae1 Nb6 16. Ne4 Nxe4 17. Qxe4 Re8
I considered a lot 17... f5 18. Qc2 g4!? 19. Nd2 Nxd5 20. Bxg4!? -/+. However, the space advantage gained by f5 could also lead to White's dangerous attack, and Black's king would be quite helpless.
18. Qd3 Nxd5
18... g4 19. Nd2 Nxd5 20. Bf3! looks wild and very unclear. Now, for a moment, I foolishly thought that the game is over: two pawns up and everything. But White still has hidden resources...
19. Bd1
Threats to h7 and f7 start to look lethal.
19... Be6 20. Bc2 Nf6
20... f5 21. Rxe6!? Rxe6 22. Qxf5 Nf4 is unclear.
21. b3 c4
There were a few alternatives:
22. Qc3
22. bxc3 bxc3 23. Qc3 with the idea Bd4.
22... Rc8 23. Qd4 cxb3
23... Bc5 24. Qxd8 Bxf2+ 25. Rxf2 Rcxd8 26. Nxg5 =/+.
24. Bxb3 Bxb3 25. axb3 Bc5 26. Rxe8+ Nxe8 27. Qxd8 Bxf2+ 28. Kxf2
The last four moves were easy to count, but here I expected 28. Rxf2 Rxd8 29. Ne5 f6.
28... Rxd8 29. Rc1 Kg7
I was very tempted to play 29... Rd3
30. b4 Kf6
This may be premature.
31. Ke3
31. Rc6+ Rd6 32. Rc8 Ng7 33. Rh8 Nf5 34. g4 Kg7 -/+.
31... Rd6 32. Nd4
32. Rc8 Ng7 33. g4 Ne6 34. Nd2 Kg6. Both 32. Rf1 and 32. Nd2 look very promising.
32... Kg6 33. Rc6 f5 34. g3 h5 35. Rc5 f4+
35... Ng7!? looks almost as good. 36. Rc6 (36. Nc6!?) Rxc6 37. Nxc6 Ne6 -+.
36. gxf4 gxf4+ 37. Ke4
37. Kd3 Ng7 38. Ke4 (38. Rc6) Rxd4+ 39. Kxd4 Ne6+ 40. Ke4 Nxc5+ 41. bxc5 b4 42. c6 b3 43. c7 b2 44. c8Q b1Q+ -+.
37... Nf6+ 38. Ke5
38. Kd3 Ng4
38... Rd8 39. Rc6
There is nothing else than 39. Ne6 Nd7+ (39... Re8!?) 40. Kxf4 Nxc5 41. Nxd8 Nd3+ 42. Ke4 Nxb4 43. Kd4 -+
It looks like White has to spend so much time in eliminating the queenside pawns that Black can promote the h-pawn at the same time.
39... Rd5+ 0-1
40. Kxf4 Rxd4+ 41. Kf3 Rxb4 42. Rxa6, a pawn and a knight down, is totally lost.
