Chessmaster 9000 on a 3.0G P4 machine (default personality with SS=12 and 128M of hash) sniffs Nxh7 after 2 seconds but then prefers Nh5+ with a 2.83 score after 5:35. After forcing Nxh7 black then responds with 3...Bc8 and a score in white's favor of 2.23 -- thus CM9 thinks Nh5+ is better. CM9k doesn't think Nxh7 is really the "smashing one".
