Chessmaster(ss=10) gets it

It says that Nxc5+ is mate in 9 in 5 seconds on PIII850

It also needs time to finish depth 8 but it has no problem to finish
it.
depth 4 is enough to see mate in 9 and the evaluation does not change at
depthes 5-8

It needs 3:46 to get the same score for Nxc5+ at depth 8.

The mate for champions is clearly more easy.
Chessmaster6000(ss=10) says mate in 12 in 1 second at depth 4.

The solution begins with 1.Bxe5+
Chessmaster does not change it's mind even after finishing depth 8.
