I have no patience to wait more than 900,000 knodes so the result is failure 15/19 >setboard N7/p7/8/q1p5/1p6/k7/8/1K1Q4 w - - 0 1 >solution Qc1 >end >-------------------------------------------- solved 16/20 80% is not so bad and I suspect that fruit2.1 can solve more position if you only give it more time. I am not sure if 20% failure is fail quite often.
