Breaking News (05.04.2023):Again 2 (two) Championships, based mainly on engines 3550+ EloThe 1st tour is played via 2 Core/Game, 2nd tour via 4 Core/GameAnd this time, all played under Classic mode (without using Evalfiles)However (like recent Tour) no much Elo progress since many time!On other hand, CF EXT is SSE41, where Cfish 030820 is POPCNTI mean both are not AVX2...probably they would get more points if...Btw, some are out (BlackMarlin 15.7 and Fisherov Monk 1.2) due toBoth performed bellow than expected..no idea..but it's waste of time!Forget everything, some are quite new but their performance is closeTo Stockfish 11 (released 3 years ago) I wonder.. what is going on?Anyhow...FUN is one of most important parts... so no BIG problem!)What I can say more (via both tours) we have several Number Ones!
