rwbean: 34... Bd6? loses a piece because 35. Nf5! threatens mate on g7. Then if 35... Qg4 36. h3 Qg6 37. Nxd6 Rxd6 38. Qxc7 or on the next move if 36... g6 37. Re1! gxf5 38. Re3 wins the queen in a different way to the game. The tactics of trapping the queen are quite subtle, so the only ...

rwbean: Just watched this one on youtube - Black had 4 minutes and White had 5 minutes and it was a sudden-death play-off, so White had to win. 63. Ke5 was the last chance to win after Black blundered with 62... b5. Earlier on 37. Qc4 was a simple win.

rwbean: If White plays 18. d3, then the next few moves are all forced on both sides: 18... Qg5 19. Bxf4 Bxf4 20. Rg1 Qh4 21. Rg3 Bxg3 22. Qxh4 Re1+ 23. Kg2 Bxh4. What's the assessment of that position?

rwbean: According to Houdini 1.5a, 54... f3 is a mate in 13. 54... f4-f3 55. g5-g6 Rd2-h2 56. Kf1-g1 f3-f2+ 57. Rf6xf2 Rh2xf2 58. g6-g7 Ne5-f3+ 59. Ne1xf3 Rf2-g2+ 60. Kg1-h1 Kg3xf3 61. c2-c4 b4xc3/ep 62. g7-g8R Rg2xg8 63. Kh1-h2 Rg8-g2+ 64. Kh2-h3 c3-c2 65. b3-b4 c2-c1Q 66. b4-b5 Qc1-h1#

rwbean: Houdini 1.5a after about an hour thinks 16...Nf5 is the best move, equal (16...Qxb2 is about +0.5 for White). 27/67 1:08:10 14,858,543,322 3,632,000 0.00 Nh6-f5 Ra1-c1 h7-h6 Bg5-f4 g6-g5 Bf4-d2 Nc6xd4 Nc5xe4 d5xe4 Nf3xd4 Nf5xd4 Be2-c4+ Kg8-h8 Rf1-e1 Ra8-d8 Re1xe4 Nd4-c6 Qd1-e1 ...

rwbean: Houdini wants to play 42. Nc4 (+1.44). Black's bishop is completely buried ... compared to move 33, where Houdini was recommending 33 ... Rdb8 (+0.48) ... and move 19: 19 ... Bd7 20. b4 Nxf3+ 21. Qxf3 cxb4 22. Rxb4 Bb5 (+0.37).
