Thought I'd copy the Obst-Morris game from the Qld Juniors as featured in the Bulletin up here, for the very unusual finish with Q+R knocking over Q+Q. (Actually it is the Black K that gets knocked over while the two poor queens can do nothing.)

1.e4 c5 2.Nc3 d6 3.f4 e6 4.Nf3 Nc6 5.g3 Nf6 6.Bg2 Be7 7.0-0 d5 8.d3 a6 9.h3 b5 10.Ne5 Bb7 11.Nxc6 Bxc6 12.e5 Nd7 13.g4 Qb6 14.Ne2 d4 15.Ng3 Bxg2 16.Kxg2 c4 17.Qf3 Rc8 18.Ne4 Nc5 19.f5 cxd3 20.cxd3 Nxe4 21.Qxe4 Rc2+ 22.Kg1 Qc6 23.Qxc6+ Rxc6 24.f6 gxf6 25.exf6 Bd6 26.Bf4 Kd7 27.Bxd6 Kxd6 28.Rf2 Rhc8 29.Kg2 Rc2 30.Raf1 Rxf2+ 31.Rxf2 Rc1 32.Kg3 Rd1 33.Rf3 Rd2 34.b3 Rxa2 35.Kh4 Ra3 36.Kg5 Rxb3 37.Kh6 a5 38.Kg7 a4 39.Kxf7 a3 40.Rf1 Rb2 41.Kg7 Rc2 42.f7 Rc7 43.Kh6 Rc8 44.f8=Q+ Rxf8 45.Rxf8 b4 46.Ra8 e5 47.Kxh7 e4 48.dxe4 d3 49.g5 d2 50.Rd8+ Ke5 51.g6 a2 52.g7 a1=Q 53.g8=Q d1=Q 54.Qg5+ Kxe4 55.Qh4+ Ke5 56.Qe7+ Kf4 57.Rf8+ Kg3 58.Qe3+ Kh4 59.Rf4+ Kg5 60.Qg3+ 1-0

Very messy and fun ending, but doesn't 55...Ke3 draw? At first I was sure it did, but actually it looks like White still wins, here's how:

56.Re8+ Kf3! (others lose immediately or shorten the resistance) 57.Qe4+ Kg3 (...Kf2 gets mated) 58.Rg8+ Kf2 59.Qg2+ Ke3 60.Re8+ Kd3 (...Kd4 is the same) 61.Qe4+ Kc3 62.Rc8+ Kd2 (...Kb3 63.Qc4+ Ka3 64.Ra8+ Kb2 65.Qxb4+ Kc2 66.Qe4+ Kb3 67.Rb8+ Kc3 68.Rc8+ Kb2 {...Kd2 69.Rd8+ Kc3 70.Qc6+ Kb2 71.Rb8+ Qb3 72.Qf6+ +-} 69.Qb4+ Qb3 70.Qd2+ Ka3 71.Ra8+ Qa4 72.Qe3+ +-) 63.Qxb4+ Kd3 64.Rd8+ Ke3 65.Re8+ Kf2 66.Qh4+ Kg2 67.Rg8+ Kf1 68.Qf4+ Ke2 69.Re8+ Kd3 70.Rd8+ Kc2 71.Qc4+ +- (or 70...Ke2 71.Qg4+ +-).

Interesting that there are wins there but they are so deep in. (The computer found all these, but it's old and slow and I had to know how to prod it.)

[EDIT nine years later: see posts below, apparently it is a draw after all!]
