Re: Using evaluation hash score as current bestscore (initial guess)

You will often see a needed estimate for the score of a move. If the move is already in the hash table, then that is used as the estimate.

Re: Where are the funs of Leela?

I think we can all agree that AlphaZero and LC0 have blown the minds of the chess community, and to some extent the entire world community.

Re: Test set from TCEC15 superfinal between Lc0-Sf

Thanks again for your efforts. I do not yet have your latest work folded into my database.

Re: Cfish, shiny and new...

Thanks, Dann! Since I'm the resident dummy here, please tell me what the clang and gcc suffixes mean. Also, what is the "vanilla" label? Back when I tested Cfish in tactical battles, I saw something strange. Although Cfish was always faster than other engines, its search depth was sometimes less de...
