Roy Chowdury Satarpsi - Jimmy Liew, Round 8

29. .. d3

Initially I intended 29... Qd2 30. Qh6 Rf7 31. e6 Re7  but then I saw the move 30. Qf3 and decided my actual move was better. However after 29...Qd2 30. Qf3 Nb4 should be clearly better for black now as he will win the queen side pawns.

30.cxd3 Nxf4 31. Nxf4 Qxf4 32. Qe2 Re8 33. Re1

White offered a draw which I declined by playing a hasty move

33...Re7 ?!

33... Qb4 Instead picks up the b-pawn for free after 34. Rb1 Re6 followed by ..Qc3

34. e6

Not giving me any second chance

34...g6 35. Kg2?

Inviting Black to exchange queens. White should take control of the long diagonal with 35. Qb2 Qg5 (Else Qf6) 36. Qe5 and White have no problems.


I did not have enough time to calculate the consequences of  35... Qg4+ 36. Qxg4 fxg4 37. Kg3 Kg7 38. Kxg4 Kf6 39. h4 Rxe6 40. Rxe6+ Kxe6 but I suspect white is faster in this pawn ending race e,g 41. Kg5 b5 42. Kh6 bxa4 43. bxa4 Ke5 44. Kxh7 Kd4 45. Kxg6 Kxd3 46. h5

36. f3 Kg7

Black should play 36...Qd5 first to tie the white queen to the defence of the e6 pawn

37. Qd2 b6

Now 37... Qd5 fails to 38. Qb2+ Kh6 39. Qf6

38. Qg5 Qf6?

Black had a last chance for a win with 38...Qd6 39. Qe3 c5 (39... Kf6 40. Qxb6) 40. Qe2 Kf6 41. Qb2+ Qd4 42. Qe2 g5 with clear advantage for Black.

39. Qf4 Rxe6

Otherwise white plays Qd6 with the better position

 40. Rxe6 Qxe6 41. Qc7+ Kh6 42. Qxb6 Qd5 43. Qe3+ Kg7 44. Qe7+ 1/2-1/2
