Kibitzer's Corner
Nov-16-10  goodevans: White could have won this with 64 Qa7+.

The first thing to notice is that black cannot allow Qh1, since Qh1 would let the white K join in and force the black K away from the defence of the pawn.

White can use the threat of Qh1 and/or diagonal checks to get nearer the black K, e.g.

64.Qa7+ Kg2 65.Qb7+ Kg1 66.Qb6+ Kg2 67.Qc6+ Kg1 68.Qc5+ Kg2 69.Qd5+ Kg1 70.Qd4+

Now the winning lines are

70 ... Kg2 71.Qg4+ Kh2 72.Kc3 zugzwang

70 ... Kf1 71.Qd1+ Kg2 72.Qg4+ etc

70 ... Kh1 71.Qf2 h2 72.Qf1#

70 ... Kh2 71.Qf2+ Kh1 72.Kc3 etc

Nov-16-10  nendwr: 64. Qg8+ isn't the best move, but still wins in all lines. Black has no good response to it: all his possible moves are bad. Three of the four resolve trivially onto the diagonal strategy:

64. ... Kh2 65. Qb1+ and we're into that line of diagonal checks with white looking slightly silly for not having noticed it earlier

64. ... Kh1 65. Qd5+ simply short-cuts to lower down the diagonal

64. ... Kf1 65. Qc4+ Kg2 66. Qf4+ and it's that diagonal again

That leaves 64. ... Kf2 65. Qf7+. If at any point black plays Kg2, then that immediately allows white's queen onto the diagonal.

The e-file moves are all obvious blunders, as they let white move his queen onto the h file and black loses the pawn.

Likewise, if black goes for 65. (or 67.) ... Kg3, this allows 66. (or 68.) Qf1, and now black can't keep white's queen off h1.

And repeatedly playing Kg1 doesn't work as: 65. ... Kg1 66. Qg6+ Kf2 67. Qf5+ Kg1 68. Qg4+ Kh2 69. Kc3 and black is in zugzwang and loses his pawn and the game.

So white should not have accepted the draw even after 64. Qg8+.

Nov-16-10  nendwr: Actually one of black's moves is even worse than I said above:

64. ... Kh2 65. Qg4 is zugzwang
