Very cool position!

Chessmaster holds onto Nxg6 after eight seconds (on a PIII-600), but then at
1:43 discards it for Nexf5!? Also note that Chessmaster suggests 1...cxb3 in
response to either move.

After 1.Nxg6 Kxg6 2.Nxf5 Rxf5, Chessmaster announces Mate in 13 in 12 seconds,
and then changes to Mate in 11 after 1:54:
