Stockfish NNUE SV Tests

[Vinvin]

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 !

CorChess is developed for long time games, because of this it's hard to give to a conclusion about CorChess with these fast games.
