1. d4 Nf6 2. c4 c5 3. d5 g6 4. Nc3 Bg7 5. e4 O-O 6. g3 I he wants to play a fianchetto, I think he'd better postpone e4.
6... d6 7. Bg2 a6 8. a4 e6 9. Nge2 exd5 10. exd5 After cd an Benoni arises where the knight on e2 is somewhat unhappy on e2 because of the manoeuvre to the ideal square c4; so Black has no troubles with a possible follow-up after 10. cxd5 Nbd7 11. O-O Qc7 12. h3 c4! 13. Be3 Nc5 14. Nd4 Re8 15. Qc2 Bd7= Aloni-Lengyel, Tel Aviv 1964
10... Nbd7 11. b3 Re8 12. O-O Ne5 13. h3 Bf5 14. Ra2 Nd3 15. Bg5 Nb4 16. Rd2 h6 17. Be3= De White set-up seems artificial and after e.g. 17...g5, to keep the bishop on the diagonal b1-h7, or after 17.. .Bd7 to go for b5 and Black is better; the next change(s) easen White's play.
17... Ne4 18. Nxe4 Bxe4 19. Nc1 Qd7 20. Re2 g5 21. Bxe4 Rxe4 22. Kg2 Rae8 23. Bd2 Rxe2 24. Nxe2 Qf5 25. Nc1 Nc2 26. Qg4 Qxg4 27. hxg4= The ending that gas resulted, is not easy to assess. Gerenally speaking, the white bishop is better than the black one, pawn d6 is weak and the white can go to the strong square f5; on the other hand the black pieces are much more actively placed than the white ones (e.g. the knight manoeuvre to f5 will take 5 moves) and Black has the possibility of the counter b5, which weakens the pawn structure of White's queenside. In the following moves White is, in growing timetrouble, playing without a plan and Black can play b5 under favourable circumstances.
27... Bd4 28. Ba5 Kf8 29. Rh1 Bg7 30. Rd1 Re4 31. Kf3 Re7 32. Bd2 b5! 33. axb5 axb5 34. Ne2 bxc4 35. bxc4 Na3 this wins a pawn and the game
36. Rc1 Bb2 37. Rh1 Nxc4 38. Bc1 Bg7 39. Rd1 Ne5+ wins a second pawn
40. Kg2 Nxg4 41. Rd2 Ne5 42. Nc3 Nf3 43. Kxf3 Bxc3 44. Rd3 Bd4 45. g4 Kg7 46. Be3 Adjourned and then resigned by White without further play. I had put 46...Bxe3 in the envelope and the rook ending after 47.fxe3 is totally won, e.g. 47...h5!.
0-1
1. c4 Nf6 2. g3 c6 3. Nf3 After 3. Bg2 White cannot reached the desired double fianchetto, because after 3... d5 4. b3 is not possible: 4... dxc4 5. bxc4 Qd4 and Black wins a pawn.
3... d5 4. b3 Bg4 5. Bg2 e6 Now 5... Bxf3 6. Bxf3 dxc4 7. bxc4 Qd4 leads to nothing because of 8. Qb3!
6. O-O Nbd7 7. Bb2 Be7 8. d3 O-O 9. Nbd2 Qc7 10. Rc1 There's no need to fear 10. e4 because after 10... dxe4 11. dxe4 Nc5 Black is ready to make use of the weakness of the d3 square.
10... Rad8 11. cxd5 At first sight this exchange seems to easen Black's play, but in fact this is the first preparation for a minority attack.
11... exd5 12. a3 a5 Black doesn't want to allow b2-b4-b5 wihout a fight.
13. Nd4 Threatens the annoying 14. h3 Bh5 15. Nf5.
13... Ne5 14. h3 Bc8 15. Qc2 Qb6 Not necessary, but not so bad.
16. N4f3 Nxf3+ 17. Nxf3 Ne8? Here 17... d4 was necessary, when there wouldn't have been a direct continuation of White's attack.
18. Bd4 Qa6 After 18... Qb5 19. Bc5 Bxc5 20. Qxc5 Qxb3 21. Qxa5 the black queen is in trouble, but the text move has serious consequences.
19. Bc5 Bxc5 20. Qxc5 Nd6 21. Nd4 Nf5 This doesn't simplify Black's position. Better was 21... Rfe8
22. Nxf5 Bxf5 23. b4! Finally this so feared march.
23... Rfe8 24. Rfe1 axb4 25. axb4 Qa3 With some pinpricks Black tries to fight the minority attack, but of course this doesn't lead anywhere.
26. e4 Now the immediate 26. b5 fails to 26... Qxc5 27. Rxc5 Bxd3
26... Be6 27. exd5 cxd5 Also after 27... Bxd5 28. Bxd5 cxd5 29. d4 Black keeps problems, but still it would have been better.
28. Qd4! Now White is winning: d5 is incurably ill.
With the text move Black hopes for 28. Bxd5? Rxd5 29. Qxd5 Qxc1!
28... Re7 28... f6 fails to 29. Rc7 threatening both 30. Rxb7 and 30. Rxe6.
29. Rc2 With the threat 30. Ra1 Qb3 31. Rb2 winning the queen.
29... Qa6 30. Rce2 g6 What follows may give the impression that this move is a positional trap on the long term. In reality it's an emergency call; in my mind I had already resigned.
31. Qf6 Looks strong, but this actually allows the opponent to bring his queen into the defence. With 31. f4 followed by 32.g4 White would easily have reached a won position.
31... Red7 32. d4 Qd6 33. b5 Qf8 34. Re3 Qg7 35. Qf4 g5! Forces the exchange of queens.
36. Qe5 h6 37. f4 Qxe5 38. Rxe5 gxf4 39. gxf4 Rd6 40. f5 Bc8 41. Re8+ Kg7 42. Rxd8 Rxd8 43. Re5 It looks like White will get the advantage anyway, but the opposite is true.
43... Kf6 44. Bxd5 b6 45. Kf2 Bxf5 Draw. Black is now a bit better:
45... Bxf5 46. Ke3 (46. h4 Bd3)
46... Bxh3 47. Rh5? Bg4 and now 48. Rxh6+ fails to 48... Kg5
1/2-1/2
