https://i.imgur.com/j6yzIXl.png I'm a bot playing ANTICHESS like a human. Rated/Casual from ½+0 to 180+180. Everyone can smash me at Level −9. Good players win at Level 0. Level 9 is for geniuses. My younger brother: @anti-anti DM for bug reports.

Fairy-Stockfish for variants, on an AMD Threadripper. I accept challenges for casual games of all non-standard chess variants, also from bots. Accepted time controls: minimum 1 + 0, maximum 15 + 10. By playing casual games I try to be a good sparring partner in any variant, also against strong opponents. Tool to create opening books for any Lichess chess variant: github.com/lichapibot/cbuild.

https://imgur.com/dAsjCS9 Hi! I'm a simple chess engine written in JavaScript. I'm not very good, this was a just for fun project. I accept standard games in casual or rated mode. I play bullet, blitz, rapid and classical. My name is a reference to The Turk: https://en.wikipedia.org/wiki/Mechanical_Turk Developed by @jlherren

simpleEval uses only material counting (1, 3, 3, 5, 9) as evaluation. 'Easy' to get a good position, very hard to convert. A GM shows how : https://lichess.org/554runt0k0Nd . Accepts rated & casual, bullet to classical.

Stockfish dev engine on an AMD Threadripper. I accept challenges from humans and bots for casual games of standard chess and Chess960. Accepted time controls: minimum 1 + 0, maximum 15 + 10.

*** This is turochamp, but tuned to the strength of the human player "larryz" *** (Currently the neural-network bot is soo bad it breaks lichess user agreement) Thank you so much for playing against my bot! I'm working to improve it. It uses reinforcement-learning, PPO (policy-gradient) and LIF-neurons to improve. I wrote this,because I'm so bad at chess, and need weak players :)

Hi there! I am a bot that runs on the GarboChess-JS chess engine. I am roughly between Stockfish Level 6 and 7 in strength. I only play standard chess.

Sawasdee krub! I am Pawny, a learning chess bot from Thailand I am a custom-built chess engine created from scratch to explore Machine Learning and chess programming. My brain is a custom NNUE (Efficiently Updatable Neural Network) trained in Python/PyTorch I am constantly learning and getting new weight updates. Every game you play against me helps my developer test my progress.

CvsEngine plays real opponents on Lichess. The deterministic self-play loop (`npm run arena:ooda`) replays the *same* CvsEngine-vs-Stockfish game every round and plateaus; live Lichess games are an open-ended stream of genuinely diverse positions to review → disagree → train on.

Visit arkivist.io if you dare Arkivist is a AUS. Chess is just a training ground for a larger beast. Good luck.
