Hello,

If I recall right (no program available to check at the moment), Rxg7 is NOT a
solution: it only leads to a draw by repetition, while Rxh7+ is a checkmate in
something like 16 (or 14). The difference is that after Rxg7 Kxg7 Rxh7+ Kxh7
Qh5+, the black king can go to g8 instead of g7, such that the bishop check on
h6 is no longer possible.

Please correct me if I am wrong, as I said, I do not have a chess program at
hand to check...

Best regards - Munjong.

• Ok, so only Rxh7+ is correct... thanks everybody! Alessandro Scotti 15:25:38 11/16/04
