Re: assembler for locking at AMD magny cours

Re: The Halloween Chess Witch 2020

Very nice pawn endgame !

Re: Stockfish NNUE SV Tests

Please, would you mind to test "CorChess NNUE 1.3" ?
I saw very good results from it recently.

The executable is here : https://chess.ultimaiq.net/stockfish.html
You probably has to download the NN-file at the bottom of the page.

Thanks !
