Here is another game that after 10 moves White has a huge advantage 0.90, therefore either Stockfish or Berseerk will win with the White sideUri Blass wrote: ↑Wed Apr 03, 2024 5:41 am There is a place for both but I prefer balanced because there is already too many non balanced games.
It is obvious after lc0 beat berserk with 1.g4 in TCEC that balanced opening lines or even no opening book is not always a draw even between top engines.
I test now stockfish15 at x nodes per move against berserk13 at 2x nodes per move(with contempt 0,10,20,30,40,50 when I started with x=1000 and double x after every match.
it is still not obvious if contempt of berserk change the playing strenght of it and it is still not clear if the berserk team is better or worse than stockfish15 in these conditions.
a win with black from the tournament.
White used 1024000 nodes per move.
