Hi!

Three examples from testsuites:

[D] 2q5/8/6p1/B6p/7k/7P/R5PK/8 w - - 0 1

1.Rc2 wins!

[D] 4kr2/5pK1/3p1Q2/1p4P1/4P3/1PP5/7b/8 w - - 0 1

1.c4 wins!

[D] 8/3p4/p1bk3p/Pp6/1Kp1PpPp/2P2P1P/2P5/5B2 b - - 0 1

1. ....Bxe4 wins!

In every position after showing Rybka the solution move the engine sees the win
immediately.

Regards!

Peter
