Re: Endgame tablebase generation for newbies
True. But running QS to establish that is needlessly expensive. You can simply seed the EGT by declaring all positions with the Pawn on the 8th rank and white to move as won. Because white cannot be in check if black has only a King. (That is, he would simply capture the black King in that case, an...

Re: Endgame tablebase generation for newbies
There exist statistics for distance to mate, but I don't think it exists for distance to promotion. You should be careful there anyway: not all promotions are winning. You should calculate until the first move with the promoted piece. It think it is sufficient to check that the promoted piece canno...

Re: YBW engines past and present?
Did you try LazySMP? Easy as falling off of a log and seems to work really well. It's insane that seemingly small tweaks to what was considered the worst-scaling algorithm (shared hash table) somehow produces the best one. I don't think the small tweaks made the difference. In the old days testing ...

Re: Dispelling the Myth of NNUE with LazySMP: An Analysis
Not long ago, it was believed by many, myself included, that making use of Hyperthreads for engine play was sub-optimal. At one point Fishtest's wikis contained guidance to Users to not use Hyper-threads. Similarly, Houdini once came with such a disclaimer. The use of hyperthreads for fishtest is a...

Re: Draw by 3 fold repetition...
It would be preferring -0.24 over -0.25. If a draw is evaluated as -0.24, then moves leading to a -0.23 evaluation would be preferred over moves leading to a draw.

Re: Draw by 3 fold repetition...
If you think that some move should be different then you should give a position and say what move stockfish played and what it should play based on your opinion. I am just asking those who know how engines are coded why a top engine like stockfish "accepts" to get into a position where the opponent...
