Best used of this game? It is probably for "bookmaking" I tend not to use engine tournament games with small to medium fixed books for book creation, because even strong engines like Stockfish still often play quite poorly when exiting the book. But I do use engine games with less limited books fro...

Arasan evaluates a Queen as worth about 3 minors plus a pawn. It has special case adjustments for many material configurations but not for Queen vs. 3 minors, which is fairly rare.

I am looking at the github source: https://github.com/mcostalba/Stockfish/ ... search.cpp

I am looking again at how Stockfish does this but there are a couple of things that puzzle me. One is that there's some code at search.cpp, line 651 to modify the hash key if a singular search is being done. But it looks like nothing is ever stored in the hash table after a singular search, due to t...

Many, many chess games are won with a gradually increasing eval for the winning side. So there really is no tactical moment where the game is won, there is just increasing pressure and eventually conversion into a mate. Carlsen is this type of player, generally: he is just really good at squeezing a...

I realize a lot of end users don't have large multicore systems but I think many chess programmers do. I have 160 cores total, including four computers with 32 cores each. There is also TCEC, which is running on very big x86 hardware, 256 threads I think in the current edition. I don't get to do tes...

ScorpioNN played an amazing game in the current TCEC Cup tournament: [Event "TCEC Cup 4 Round16"] [Site "https://tcec-chess.com"] [Date "2019.10.22"] [Round "1.13"] [White "ScorpioNN v3.0.3-n_maddex_INT"] [Black "Ethereal 11.63"] [Result "1-0"] [ECO "E60"] [WhiteElo "3707"] [BlackElo "3746"] [PlyCou...

This was a rapid game so White may not have had 30 seconds to make the right move, and would have required even more than that if running on lesser hardware. Stockfish will find Qxd3 right away.
