Hello! I'm Humaia! One of the most human bots on Lichess! I make moves based on the estimated probabilities of a 1400 blitz rated human player. (randomized Maia 1400 network) I hope to be a good sparring partner for average to beginner players! (I don't accept bot challenges) Play me on shorter time controls for more of a challenge! Or try my stronger sibling, @Humaia-Strong!

Fairy-Stockfish for variants, on an AMD Threadripper. I accept challenges for casual games of all non-standard variants, also from bots. Time controls from 1 + 0 to 15 + 10. By playing casual games I try to be a good sparring partner in all variants, also against strong opponents.

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.

Simulation of a club-level player. Uses book openings, then plays an intuitive middlegame leveraging human-understandable tactics. Sometimes miscalculates complicated positions. Do not underestimate. Accepts timed standard challenges in the range of blitz, rapid, and classical. Please consider donating! BTC: bc1q35aysf8n9cuq4nva3jkalp94j4hs8suddtr67z

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.

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. I can play multiple games at once, though bullet challenges must be with at least 1s increment for every game that I'm currently playing. Message @hasc if you have any questions or comments.

Chess Engine written in Scala. Far from perfect.

Maello is a chess engine written in c++.

A simple chess engine written in Rust. It implements standard chess rules, move generation, evaluation, and uses Negamax search with Alpha-Beta pruning, Quiescence Search, and a Transposition Table for finding the best move in a given position.

This is the chessengine Rodent IV (running on NetBSD) which aims to be an entertaining sparring partner for us humans. Strength is now set to "Elo" 1200 . Style/Personality: "Tal". Rodent does use an opening-book for the first 6 moves with a broad repertoire but no endgame-things. If you liked/didn't like the style, drop a note :-)

Play a game against an emulated dedicated chess-computer from the 1980s. Today it's the Schachcomputer SC2 from VEB Mikroelektronik „Karl Marx“ Erfurt (GDR) with maybe 1200 "Elo". Strength is fixed to "Level 3" - but it plays almost instantly as emulation has been speeded up - however you're free to chose your preferred time-settings (minimum 3min+5sec, max. 30min+60sec). :-)

Patched GNU Chess bot by @oPbAi that would happily blunder a rook if it gets to capture en passant in exchange - or if it can make you do so! If no en passant happens, I'll crush your soul! Try finding ways to use this to your advantage! I hope this will create some funny situations. NO CHEATING! If you resign in chess, you resign in real life!

Hi! I'm CloudNetBot, and I get about 25% of my moves from online databases: lichess cloud, ChessDB, opening explorer, and online syzygy (egtb) (Because of this, I can lose; there are a lot of errors in the online databases). I run on the GitHub Actions cloud server 24/7, with the latest Stockfish dev. I really hope this doesn't break.. Good luck! :)

Im currently in my 23th version. V1 (~1100 ELO) : - Fixed 4 ply w capture heuristic V2 (~1200 ELO): - It Deep. with TT - PST - Move ordering using MVV-LVA V3 : - Quiescence search - Delta pruning - Better MVV-LVA V4: - Repetition checks + simple mates V5: - Python is slow, now I use Rust Lots of small upgrades later and more to come.
