The Joselito Hustle

The PNG's Joselito Marcos dropped in and posted an analysis of the last few moments of his game against Marc Vlietstra from the Gold Coast Open. Here's the starting position.

The ex-Pinoy lost this one, but not before giving his Western Australian opposition a tough fight until the very end. Joselito takes over from here.

2009 Gold Coast Open
Vlietstra, Marc
Marcos, Joselito

41. bxc3 Bh3!

(Black only has 23 seconds left on his clock at this juncture; White still has more than 3 minutes.)

42. Qe7+ Ka8 43. Qg5 Rb1+

(An alternative was 43... Rb2. During the postmortem Vlietstra tried 44. Rg1? Bxg2+ 45. Rxg2 Rb1+ 46. Nf1 Rxf1+ 47. Kh2 Qh7+ 48. Kg3 and now with a clear head, and possibly more time, Black could win with 48... Rf8!. Correct was 44.Qg8+.)

44. Rxb1 Qxb1+ 45. Nf1 Qxf1+ 46. Kh2 Bxg2 47. Qxg2 Qf4+ 48. Kh3 Qh6+ 49. Kg3 Qg5+?

(The check on the WRONG SQUARE. In his excitement Black missed 49... Qg6+!! 50. Kf2 Qc2+ 51. Kg1 Qb1+ 52. Kh2 Qh7+ 53. Qh3 Qc2+ 54. Kg1 Qb1+ 55. Kh2 Qc2+ 56. Kg1 Qb1+ 57. Kh2 Qc2+ is equal)

50. Kf2??

(White panicked as he was becoming short of time while Black was gaining his. 50. Kf3! -- a shame that White overlooked this excellent chance -- Qf5+ 51. Ke3 wins)

50... Qd2+ 51. Kg1 Qd1+??

(Again a check on the wrong squate. With this move Black loses his second and final opportunity to even things up. For Black not to lose all he has to do is keep on checking on the long diagonal b1-h7. Better was 51... Qe1+! or 51... Qc1+! Check this out with your silicon friends.)

52. Kh2 Qh5+ 53. Qh3 Qe2+ 54. Kg3 Qe3+ 55. Kg4 Qg1+ 56. Kf5 Qf2+ 57. Ke6 Qxa2

(The game dragged on with Black stripped off his d pawn and White his c and d pawns but was able to promote his e pawn to a queen. The succeeding desperate checks by the black queen was deptly evaded by White to score the win.)

58. Kxd5 Qb3 59. Qc8+ Ka7 60. Qc7+ Ka6 61. Qc6+ Ka7 62. Qd7+ Ka6 63. e6 Qxc3 64. e7 Qf3+ 65. Kd6 Qf4+ 66. Kc6 Qe4+ 67. Kd6 Qxd4+ 68. Kc7 Qb6+ 69. Kc8 Qc5+ 70. Qc7 Qf5+ 71. Kd8 c3 72. e8=Q Qd5+ 73. Qcd7 Qg5+ 74. Kc7 Qf4+ 75. Kc8 1-0
