neural_network_chess VS lichess-bot

Basically, MCTS is used in combination with reinforcement learning. This ensures that we get better evaluations for non terminal positions in training games. You might want to have a look at my free book @ https://github.com/asdfjkl/neural_network_chess

So consider instead keeping a running score of the position, rather than recalculating it in full every time. One of the main tricks behind Stockfish NNUE, the current top chess engine, is a clever way of not needing to fully recalculate the full neural net every time, but to do a delta update for each move for a substantial part of the network. I forget the main paper about that, but you can read about it in https://github.com/asdfjkl/neural_network_chess.

My book https://github.com/asdfjkl/neural_network_chess covers some of these topics...

Neural Networks For Chess

Shameless self-plug: I wrote a book about neural networks in chess and you can get a free PDF here https://github.com/asdfjkl/neural_network_chess (no ads, no fremium)

Clone https://github.com/lichess-bot-devs/lichess-bot.git into your new project! Make sure you have github installed!

https://github.com/ShailChoksi/lichess-bot is a straight forward way to use any UCI engine with lichess. There are also a few libraries for move generation mine: https://github.com/Disservin/chess-library , libchess: https://github.com/kz04px/libchess , surge: https://github.com/nkarve/surge . These are C++ ones, for rust theres https://github.com/analog-hors/cozy-chess . In python you could use python-chess but its incredibly slow for engine stuff writing your own will probably be faster if you know what you are doing.

I would recommend downloading this bot, written in Python: https://github.com/ShailChoksi/lichess-bot

Once you have these basic UCI commands implemented, you can use this application to run your engine as BOT on lichess.

The bot uses the Shail Choksi's lichess-bot package (link) and stockfish. It's currently running on pythoneverywhere.com. I am very much a hobbyist and this is the first time I've done anything "useful" with coding. If you encounter any bugs, DM me and I'll do my best to fix them.

You can make a lichess bot with your engine (https://github.com/ShailChoksi/lichess-bot or similar API). The instructions are all fairly straightforward, but if you need any help feel free to reach out!

If you just want to make your engine play some games, with a uci interface you can quickly setup a bot account on lichess and challenge any available bot. https://github.com/ShailChoksi/lichess-bot
