Re: Hard-Talkchess-2020 set, final release

I tested the new version of Corchess : NNUE-1.4 (it's the update with the big net). 2 tests, one with the defaut NN : nn-7756374aaed3 and another with the bit more recent nn-8a08400ed089.

Re: Computers are now superior to humans in turn-based strategy games

Computers are now superior to humans in turn-based strategy games(chess, backgammon, go, checkers...). It's time for real-time strategy games(Red Alert, Football, Basketball, Cossacks...). Computers will soon take over the dominance in this area as well. I thought they already had? e.g. https://www...

Re: Multi-threaded shortest mate solver

And may be, integrate the code in the official Stockfish to improve its mate solving ability. I'm afraid that finding the shortest possible mates wouldn't improve Stockfish's strength at all.
