    Ah I see, there was probably so many pieces on the board that stockfish couldnt count all the way to the tablebase position and see that its winning and made this non sense which, in computers eyes is the same outcome (win) but for me as a person seems as a dubious way of playing (making your task harder unnececarily)

  • snappingbear


    2 muaj më parë

    @david hanley NO it IS not. If you were involved in its development or understood the code base and the neural networks developed for it you would know that.

  • Quag


    2 muaj më parë

    Stockfish's evaluation now uses a fast, shallow neural network (NNUE) in combination with its old handcrafted evaluation. That's why it's playing more aggressively and makes sacrifices more often. NNUE was trained from Stockfish games - there was no tuning from Leela.

  • david hanley

    david hanley

    2 muaj më parë

    @snappingbear I'm certainly aware of that, but stockfish is using attacking tuning it didn't have before. Contempt is more about avoiding draws, not having more awareness of how open lines to the king compensates for sacrificed material.

  • snappingbear


    2 muaj më parë

    Actually the ability to alter Stockfish's aggression has been a feature for a long time, it's called "contempt". It is generally not a good idea to change the default as making it more aggressive and contemptuous of its opponent leaves it more vulnerable to counter attacks.

    Stockfish gained about 300 rating points since year 2017, and would win about 2/3rds of all games against its former self. So I think there's no question that everyone including the Stockfish team would be eager for a rematch. Perhaps only AlphaZero is glad that it quit...

  • Corteum9000

    I don't understand Leela's Kc7. The only move, according to my engines, was Be6, which draws after Qxd6 Bxb8 Rxa5 Kxb8 Rfa1 Kc7 Nxb7 Kxb7 Rb5+. But Kc7 just loses on the spot.

    What was the time control? I've noticed LeelaChess (Lc0) on faster time controls does not play so strong. But obviously Stockfish is a beast no question asked. Their is now a LeelaChess version with NNUE technology (so all you guys don't have to buy expensive GPU to run) call LcFish . It was developed jointly with the Stockfish team.

    Leela outplays stockfish (maybe not anymore but it sure did without NNUE) while stockfish outcalculates - if the position gets closed or like half-closed leela can get great pieces and get an attack for like a piece or something and crush stockfish, but these positions with opposite sides castling are plain calculation, if course it can't even draw
