Debugging is twice as hard as writing the code in the first
place. Therefore, if you write the code as cleverly as possible, you
are, by definition, not smart enough to debug it.

Re: Best move Qf6+
Does the "score" matter? The eval doesn't do egtb probes, nor captures, but it does realize the problem white has. I want my program to play the best move. All too often I don't agree with the score, but if I agree with the move, that is what counts.jwes wrote:The problem is that Crafty considers the terminal position to be a moderate advantage for black when it is really dead lost.bob wrote:That's the only Move Crafty considers beyond 3 plies.Howard E wrote:[d]3Q4/pp3qk1/6p1/3P3p/1P5P/P1K1p3/1P6/8 b - - bm Qf6+;Code: Select all
