Games from Selangor Open

Jimmy Liew - Srinath Narayanan
19. f4! Nd7? It was better to sacrifice back a pawn with 19...c4 to gain a tempo., 20.Nxc4 Nxc4 21. Qxc4 Nc7 22. 0-0 with better position for white.  20. Nxc8   Now black has serious weaknesses on the white squares around his king. 20...Rxc8 21. Bg4 Nc7 22. Bg3   Readying the attack 22...Rb8 23. Qc2 Bd4 24. Be6+ Nxe6 25. dxe6 Black knight is driven further away from the defence of the king since black cannot capture on e6 with the queen. 25... Nb6 26. O-O-O Bxc3 27. bxc3 Nc4 28. Rh6 e2 Black hopes for 29. Rdh1 Ne3 30. Qd3 Nf5 31. Rxh7 Qxh7 32. Rxh7 Kxh7 and avoids getting mated 29. Qxe2 b5 30. Rdh1 Qg7 31. Qd3 Rb7 32. g6 Rfb8 33. Rxh7 Qf6 34. e7

Black is helpless after 34...Nb6 (to stop Qd5+) 35. Rh8 Qxh8 36.
Rxh8 Kxh8 37. Qxd6. If 34...Rxe7 then 35. Qd5+ Re6 36. Rh8+ Kg7 37. R1h7+ Kxg6
38.Qh5 mate


Jimmy Liew - Nicholas Chan

In this position I came up with a spectacular  20. Rxf7 This is a big gamble trusting my instinct that there must be something over the board although I could not see it right there.  Nicholas declined with Qxb2 To rub it in, I had spent a considerable amount of time whereas he just took a few minutes. Perhaps he trusted me too much.  However the computer found some very nice moves to support the attack. The complications start with 20....Bd4+ (Black must block the white queen from getting to d5 where it delivers mate on f7 or g8) 21. Kh1 Kxf7 22 Bc4+ Kf8 23. Qh5!! ( I did not see this move on the board only considering 23. Qf3+? Nf6 24. Rf1 when white really does not have enough for the attack e.g 24....Ne5 and black is already safe) 23... Bf2! (the only move to prevent mate!)

24. Rxf2 Re1+ 25. Bf1 Rbe8 (Necessary as white threatened Rxf6 and Bxe1) 26. d7 Rd8 27. Qxh7 (Now 27.Rxf6 no longer works because after 27...Qxf6 the bishop on f1 is hanging.) Ne7 28. Qh4 (Threaten Rxf6 again) Re6 29. Qh5+ Kf8 30. h3  (Escape square so the bishop on f1 can move) Rxd7 31. Bc4 and white has more than sufficient compensation in the form of the exposed black king.
Qxb2 21. Rxd7 Qxc3 22. Rc1 The engine likes 22. Bxe5 Qxe5 23. Bf3 which looks better for black as the position is simplified.

Qe3+ 23. Bf2 Bxh2+ 24. Kf1 Rf8 25. Bc4+ Kh8 26. Rf7 Rxf7 27. Bxf7 Qf4 28. d7 Rd8 29. Be6 Qf6 30. Bh3 Rf8 31. Rc2 Bg3 32. Qe1 ?  The only move was 32.Rd2 Bc7 (33...Bxf2 34. d8=Q attacking the queen on f6 renders the discovered check ineffective. 33. Qf3 Qe5 34. Qd5 Qa1+ 35.Rd1 Qf6 and white has some compensation in the advanced d-pawn.

 32... Ne5 (Black threatens 33...Nd3 winning material.) 33. Rd2 Nc6 {Suddenly it is over.
The d-pawn is neutralized and black just swaps all major pieces to win the
ending.} 34. Kg1 Bxf2+ 35. Rxf2 Qxf2+ 36. Qxf2 Rxf2 37. Kxf2 Kg8 38. Ke3 Kf7
39. Ke4 Ke7 40. Kd5 Nb8 41. Kxc5 Nxd7+ 42. Kd4 Kd6 43. Bf5 h6 44. Bc2 b6 45.
Ke4 g6 46. Kd4 Ne5 47. Be4 b5 48. axb5 axb5 49. Bc2 Nc6+ 50. Ke3 g5 51. Ke4 Kc5
52. Bd1 Nd4 53. Ke5 Kc4 54. Kf6 Kc3 55. Kg6 b4 56. Kxh6 Nc2 57. Kxg5
(57. Bh5
b3 58. Bf7 b2 59. Ba2 Nb4 60. Bb1 Kd2 61. Kxg5 Kc1 62. Bf5 Nc2 {is the
standard win in this ending}) 57... b3 58. g4 b2 0-1
