Missed Chance

In the recently completed "Youth vs Experience Tournament" the following position was reached in a game between Ivan Cheparinov and Ljubomir Ljubojevic:





A kibitzer at one of my favorite chess web sites pointed out that here, Ljubojevic, playing Black, missed playing 58 .. e4! If White then plays 59. fxe4 then 59. ... Ne5+ 60. Kc3 Nxd3 Kxd3 with material advantage for Black. If, after 58. .. e4!, White plays say some rook move, then Black can play 59. ... exf3 winning a pawn.


The actual game ended in a draw, and had a somewhat absurd ending from what I understand: the players repeated the position from move 68 to 84.

White To Win a Pawn In Five Moves

While editing this blog, I deleted one of my posts by mistake. It had to do with a position I reached against a program, set at a low level. I had the position saved on the computer, so I'm sort of able to redo the post. The position reached was:



Here, White can win a pawn in five moves: 1. Qa8+ QxQ 2. RxQ+ Kc7 3. Ra7+ Kc6 4. RxR KxR 5. Bxc5

Sharp Win By Gelfand

In the Tal Memorial Tournament a sharp game between Shakhriyar Mamedyarov and Boris Gelfand went: 1. d4 d5 2. c4 c6 3. Nc3 Nf6 4. Nf3 e6 5. Bg5 h6 6. Bh4 dxc4 7. e4 g5 8. Bg3 b5 9. Be2 Bb7 10. e5 Nd5 11. O-O Nd7 12. Nd2 Qb6 13. a4 a6 14. Nde4 O-O-O 15. Bh5 Nf4 16. Bxf7 Nxe5 17. Bxe6+ Kb8 18. Ne2 Bg7 19. Nxf4 gxf4 20. Bxf4 Rxd4 21. a5 Qd8 22. Qe2 Re8 23. Rad1 Ka8 24. Be3 Rxd1 25. Rxd1 Nd3 26. Bf5

Position after White's 26th move


This position is like a chess problem. Here, what move can Gelfand make that can eventually give him a material advantage? The answer is 26. ... Qd5! Play continued: 27. Qg4 Bxb2 28. h4 Bd4 29. Bg6 Rg8 30. Bxd4 Qxd4 31. Qe6 Qd5 32. Qe7 c5 33. f3 Qd4+ 34. Kh1 Qg7 35. Qxg7 Rxg7 36. h5 b4 37. Kg1 Bxe4 0-1


How To Avoid Chess Blunders?

Recently I've been thinking, "How to avoid chess blunders?" Take, for example, the following position which occurred between Emanual Lasker and David Janowski in their World Championship Match:





Janowski blundered with 19. ... Rd6? Play went: 20.Rxd5 Rxd5 21.Qxd5 Qxb4 22.Rxc6 1-0

In order to avoid blunders, it may be useful to think, before the move is made, "After I make this move, are there checkmating threats against my king?" Also, it might be useful to think, "After I make this move, what would happen if exchanges are made?" It seems to me that not just this example, but in other examples, blunders are refuted after exchanges.
