It’s been a while since I’ve posted any chess, and development in the engine world has continued apace, so it was time to see how they do with Douglas Modern Chess.

I consulted recent events at https://www.tcec-chess.com/ as well as the rankings at https://ccrl.chessdom.com/ccrl/4040/ and selected the following engines to compete:

Bezerk
Stockfish 15
Ethereal
SlowChess 2.83
Koivisto_8.9
RubiChess
PeSTO
rofChade
Seer
arasanx-64
zahak
Igel
velvet-v3.3.0
