Today in a game with blik on FICS, my program reached the following position: 2r1r1k1/3p1p1p/p2Qp1p1/q1N2P2/Pn1B1P2/6P1/2P3bP/2KRR3 b - - After about 3 seconds my program played ... Bf3?? which loses to Qe5. I ran my program on the position after the game it only then did it realise that ... Na2+! wins (and wins big). It takes it 9.5 seconds to realise that, a little too slow for the game. Crafty 16.16 takes about 20 seconds to find ... Na2 (in the meantime it plays ... Rb8 which it says wins material) on the same hardware (P233, 4MB hash table). Anyway, here is my program's output. What does your program say about the position?
