Xu Hua Hua - Jimmy Liew, DATMO 2009

Xu Hua Hua - Jimmy Liew, DATMO 2009

I desperately wanted to win this game. The previous round I had managed to lose a won game.

In this position, I came up with a surprise sacrifice. Though I do not think it is correct, I was banking on my opponent time as she spent a lot of time on the opening and early middle-game

20.... Nxe5!? 21. Qd6

White can take the knight. Now 21. fxe5 Qxe5 22. Qa2 Bc6 (This looks dangerous as the black queen lines up on the long black diagonal. But white has 23. Rf4 Rxf4 24. gxf4 Qd5 25. Kf2 (escape to the queen-side) Qg2+ 26. Ke3 and to safety.

21...cxd3 22. fxe5 22... dxe2 23. Rxf8+ Rxf8
24. Qxd7 Qc5+

I spent some time deciding between this and Rf1+ e.g 24... Rf1+ 25. Kg2 Qxe5 26. Qe8+ Rf8 27. Qc6 (27. Qb5 Qe4+ 28. Kh3 Qf3) 27... Qf5 28. h4 Qf1+ 29. Kh2 Rf2+ 30. Bxf2 Qxf2+ 31. Kh3 Qf1+ black can only get a draw.

25. Kg2 Qc4 26. Bf2??

This costs her the game. White can defend by occupying the long white diagonal with her queen. 26. Qb7 h5 when in spite of an extra piece, white has no way to activate his pieces. 27. h3 Rf7 28. Qa8+ Rf8 29. Qb7 Rf7 an repetition.

Qxc3 27. Bd4

27. Qd4 loses to Rxf2!

Qf3+ 28. Kh3 Qf5+ 29. g4 Qf1+
30. Kh4 e1=Q+ 31. Rxe1 Qxe1+ 32. Kh5 g6+ 33. Kg5 Qd2+ 34. Kh4 Qxh2+ 35. Kg5 Rf7
36. Qd8+ Kg7 0-1
