Re: Yet another tt issue

Interesting. So, Sven, you only use the TT in zero-window/non-PV nodes? Also, what's the harm in using it at the root if the depth is appropriate, it's an exact type TT entry, and the score it holds is between alpha and beta? Feels like I've tried it every which way, and currently, I do use the TT i...

Grouped by 4, each position (of the 4) should have identical evaluation. If not, then there is an evaluation bug.

Just need to get the diagram and pgn tags working again, and we're back in business. :) Oh, and I agree the real names display in the old forum was nice, though it still showed usernames ...

I really hope that's not true considering all the work, including eval tuning, I've put into creating an almost 2400-rated engine. :)
