I'm a little confused...is the move 81.h4 or 81.Rh4? The PGN that you gave shows that h4 was played, so I'll assume that was the move. Chessmaster 9000, on a P4-2.4, finds h4 in two seconds, and gives it a nice eval after 33 seconds: Time Depth Score Positions Moves 0:00 5/9 0.43 119437 1.Rh5 Kf7 2.h4 Rxh4 3.Ke5 Kg6 4.Kxe6 Rh1 5.Kd5 Rxh5 6.gxh5+ Kxf6 0:01 6/10 0.30 278170 1.Rh5 Kf7 2.Rxg5 Rxh3 3.Ke5 Re3+ 4.Kf4 Kxf6 5.Rg8 Re2 6.g5+ Kf7 7.Rd8 0:01 6/10 0.48 353200 1.Kd3 Kf7 2.Ke2 Ra1 3.h4 Ra2+ 4.Kd3 Ra3+ 5.Kc2 gxh4 6.g5 Ra2+ 7.Kd3 Rg2 0:02 6/10 0.86 569993 1.Ke3 Kf7 2.h4 gxh4 3.g5 Re1+ 4.Kf2 Re5 5.Rh7+ Kf8 6.Rg7 h3 7.g6 0:02 6/10 1.08 766696 1.h4 gxh4 2.g5 h3 3.Ke5 h2 4.Kd6 e5 5.Ke7 Rf1 6.Rxh2 0:04 7/11 0.88 1098825 1.h4 gxh4 2.g5 Kf7 3.Ke5 Re1+ 4.Kf4 Rf1+ 5.Kg4 Rg1+ 6.Kxh4 Rh1+ 7.Kg3 Rg1+ 8.Kf4 e5+ 9.Kf5 e4 10.Kxe4 Rxg5 0:07 8/12 0.86 1969808 1.h4 gxh4 2.g5 Kf7 3.Ke3 Re1+ 4.Kf3 Rg1 5.Rh7+ Kg8 6.Rg7+ Kf8 7.Kf2 Rd1 8.Rh7 0:13 9/13 0.84 3873000 1.h4 gxh4 2.g5 Kf7 3.Ke3 Re1+ 4.Kf2 Re5 5.Rh7+ Kf8 6.Rg7 h3 7.Kg3 Re3+ 8.Kh2 Rf3 0:33 10/14 1.30 9545569 1.h4 gxh4 2.g5 Kf7 3.Rh7+ Kg6 4.Rg7+ Kh5 5.f7 Rf1 6.g6 h3 7.Rg8 h2 8.f8=Q h1=Q 9.Rh8+ Kg4 10.Rxh1 Rxf8 0:59 11/15 1.36 17482639 1.h4 gxh4 2.g5 Kf7 3.Rh7+ Kg6 4.Rg7+ Kh5 5.f7 Rf1 6.g6 h3 7.Rg8 h2 8.f8=Q h1=Q 9.Rh8+ Kg4 10.Rxh1 Rxf8 11.g7 2:06 12/16 1.62 37768754 1.h4 gxh4 2.g5 Kf7 3.Rh7+ Kg6 4.Rg7+ Kh5 5.f7 Rf1 6.g6 h3 7.Rg8 h2 8.f8=Q h1=Q 9.Rh8+ Kg4 10.Rxh1 Rxf8 11.Rg1+ Kh5 12.g7 4:52 13/17 1.72 88163809 1.h4 gxh4 2.g5 Kf7 3.Rh7+ Kg6 4.Rg7+ Kh5 5.f7 Rf1 6.g6 h3 7.Rg8 h2 8.f8=Q h1=Q 9.Rh8+ Kg4 10.Rxh1 Rxf8 11.Rg1+ Kh5 12.g7 Rg8 jm
