Re: Does any engine see this draw?

In this game, Gaviota got very lucky and drew it. Both engines thought black was winning, but they entered to draw.

I have never found an engine, that was exceptionally stronger in the endgame. Once i was told, that shredder is especially strong in the endgame, but after hours of work i could not verify that claim. I believe that the strongest engine is strongest in the endgame too. My recommendation for serious ...

Re: The debacle

Why not stick with the experts? Assessing an attack is truly a search related thingy. You cannot statically evaluate an attack. Not even humans can do that. E.g. give white here a single move more and suddenly his own attack comes into swing, turning the table completely: [d]1r1q1rk1/4ppbp/2ppbnp1/n...

Re: Test suite for Stockfish

[D] rk1b4/p2p2p1/1P6/2R2P2/8/2K5/8/5B2 w - - My copy of stockfish detects Rc8 on depth 15. I don't have any problem with that. [D] k2N4/1qpK1p2/1p6/1P4p1/1P4P1/8/8/8 w - - Whoops. Nc6 is not detected, not even on depth 48 or so. But when i try this move for myself it detects its usefulness quick as ...
