In the Sicilian Defense, Sveshnikov Variation with 7. Bg5, I followed book moves up to and including 17… g6 . This last move might be an inaccuracy by Black, since the evaluation following this move is +0.50 while before the move, the evaluation is +0.12 . [ +0.12 is better than +0.50 from Black’s point of view] White then plays 18. h4. White won in 94 moves. Next, I’ll try versus Stockfish 15.1 depth=41, deviating from the depth=39 game (the one discussed here) only when a new move appears for Black at depth=41, compared to the move chosen at depth=39.
The Various engines versus Stockfish 15.1 depth=39 game is at the URL: https://www.chess.com/analysis/game/pgn/2LBG7nTK8z?tab=analysis .
Generally speaking, it’s increasignly difficult to score a win versus Stockfish at a fixed depth, as the depth increases. I expect that trying to score a win vs Stockfish 15.1 depth=49 would be very very difficult, if starting from a balanced position.
