It's a pleasure to annonce the new ShashChess 12 release with a lot of novelties: ... Hi ! I tested ShashChess 12 on the Hard-Talkchess-2020 set and I saw a strange thing : the search is NOT consistent with 1 thread when I restart the engine on the same position. I tested with this position : 1nb3r...

Pro Value is using multipv=8 and... Thanks for clarifying, didn't know MultiPV to be involved too in presearch. So if you chose "Tactical" in addition, is then the number of internal primaries of the Tactical- mode (if set higher then 3) presearched with less pruning or yet 8 only still? I have cod...

Hi Louis! That's very fast! I haven't studied the code, but I'm guessing that much less LMR is being applied. Now that I'm curious, let me try Komodo with LMR totally disabled... Schwabli (my chess- PC) is busy right now, so I'm curious for your results. As for Michael Byrne's r- versions, there is...

I have a question that I will work into a chess hardware question. My computer downloaded a BIOS update on its own. I let it when it asked. I have never updated my BIOS before. I am wondering what it does for the computer and will it help chess engines in anyway. I read that it helps your hardware ...

As many of know, NN engines have been reporting WDL data with Scoring Percentage for some time. A while back, I took their formula to convert to a centipawn and applied it the centipawn evaluation to come up with LC0 like output for the Honey family of engines. Today, the developers of SF committed ...
