I had Berserk at depth about 27 play several games against Stockfish 15.1 at depth=27. The opening was a balanced one, meaning that neither side had a significant advantage out of the opening, although White was slightly better (Sveshnikov Sicilian with 7. Nd5 ). Out of the several games played, a few gave an advantage of about +0.6 to White, but none were winning. I continued one of these games (with takebacks of unpromising moves/lines allowed) with Lc0, always playing against Stockfish 15.1 at depth=27. Lc0 ended up with and advantage of about +1.2 ( which is quite significant). Lc0 seemed to make mistakes, so I switched to Berserk 11.1 at depth=35. In the end, Berserk won and the game lasted 96 moves. Berserk made a brilliant move: 52. Be7 and so did Lc0, at 47. Rxb7 . The chess dot com game review and Lichess analysis both find that the move 50… Kh8 is a mistake. However, Stockfish 15.1 at depth=44 gives the best move as 50…Kh8 with an evaluation of +2.26 .
Here is the evaluation after Black’s move number:
10 +0.37/60
15 +0.42/69
20 +0.32/49
25 +0.29/47
30 +0.55/45
35 +0.42/54
40 +0.60/47
45 +1.33/41
50 +2.26/44
