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

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 20 + 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.

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.

Hi! I'm StupidChessRobot, a chess engine from https://github.com/ollybritton/StupidChess. I use Alpha-beta search, an AVX2-accelerated NNUE brain, a transposition table, multithreading, and Syzygy tablebases for the endgame. --- Running a custom Go chess engine on a 6-core VPS (Intel Haswell-class @ ~3.0 GHz, no hyperthreading, 12 GB RAM, AVX2 + BMI2, 6 search threads).

https://i.imgur.com/EBx8n0g.png I'm built entirely in Java by https://lichess.org/@/marvk and am currently sitting at 600 kNPS on an i5 4690k. Check out the GitHub link below to check out my source code.

Accepts Bullet, Blitz and Rapid games, both casual and rated, against both humans and bots. Plays at most one game at a time. A bot by @adario7, with a custom search algorithm written from scratch. Uses pondering and a small opening book but no endgame tables.

Incremental move list update :), Iterative Deepening, Alpha-Beta, Quiesence search (same-field recapture), TTable, Killer moves, Null move pruning, LMR/PVS, PeSTO evaluation, passed/isolated pawns, Opening book, EGTB, Single-Threaded. CPU: Celeron J3160 1.6GHz. About 600kN/s. Usually 10-12 plys in midgame, more in endgame.

I am a chess engine written in C++ by @kevlu8 and @wdotmathree, started when we were in middle school and picked back up in late February 2025! BLOCKING ALL STOCKFISH BOTS. If you don't want to get blocked, don't challenge! 2 threads, 1024MB hash Estimated CCRL rating: ~3720 Please challenge *with increment*! The ping between us and Lichess servers make sudden death impossible.

This engine is a modified version of Stockfish 11, redesigned to favor aggressive and dynamic play. It prioritizes initiative, attacking chances, and tactical complexity over conservative evaluation, making it a challenging and entertaining opponent that constantly seeks active positions and decisive play.

This is a human-aligned bot calibrated to play at roughly a 1600 Elo level. It uses a BT4-based transformer architecture and was trained exclusively on human games from players in that rating range. Source code is available on: https://github.com/hrschubert/dala-training

MostlyHuman plays like a human, mostly. Openings come straight from the Lichess Opening Explorer, sampled at the exact rate 1800-2000 rated players actually choose them — the full human range, mainlines to dubious gambits, in real proportions. Then Maia-1900 neural net takes over: trained to predict human moves, no search. No engine lines. You won't get the same game twice.

I am the big brother of @Randmaster_Bot I play the same way, except I use the endgame tablebase hosted here on lichess. If you do not have a winning position by the endgame, you will most likely not win. I play standard chess, 960, antichess and atomic. Any time control, casual or rated

Hi! I am a studylover robot! I was created by the team https://lichess.org/team/studyfansh-a-n-g-o-u-t and https://lichess.org/team/attack-at-the-knightmares My actual creator: Mahadevvp-2012 My contributor: Chessrocker2, Satvik4, Samadarshi_ch The idea was given by: yomiwoo Thanks to: Sreeragj, Pasqov for encouraging me!

I don't play the best move. I play the one you're most likely to get wrong. Every move, I predict your reply with a neural net trained on human games (Maia-3), then pick whatever gives you the most ways to go astray. When the game ends I'll tell you your costliest mistakes. Accept bullet, blitz, rapid. Rated or casual.

Chess engine written in C++

sunfish's neural sibling: a NNUE python engine in 4096 bytes. The network accumulator and evaluation live in ONE Python big integer (~20 big-int operations per eval), trained on 30M lichess positions. Hosted on an Ampere A1 (2 dedicated ARM cores, 12 GB), ~22 kn/s on pypy3. Pondering enabled. Source: github.com/thomasahle/sunfish.

Ursus is a UCI chess engine written in Zig. Currently under development so strength may very. Running on limited hardware. An intel NUC: Intel Core i5-4250U. With 2 threads and a 2gb hash table. Plays bullet, blitz and rapid up to two games at a time Now playing Chess960! Good luck!

SouthBot is a solo project. C++ alpha beta search function with a NNUE evaluation trained entirely on its own games. Each net learns from games played by the previous version of the engine. Switched to NNUE from hand-crafted evaluation on 8/28/26

LineNetBot is a one forward pass 15 million paramater CNN bot that predicts the line instead of only the next move. The intention was to allow for a one forward pass bot to have a deeper understanding and to blunder less tactics. LineNetBot is a very good training tool for all players under 1500 elo. With play focused on defending and protecting your pieces LineNetBot will eventually blunder.

Self written UCI c++ chess engine. AB, TT, iterative deepening, sliding window, NMP, lazy cutoffs, MVVLVA, hashsort, killers, evasion, single core and a lot of unfinished ideas and bugs :) https://gitlab.com/morengo75/bbchess accepts blitz, rapid, bullet but bullet time control <60 with inc pls, because of 0.5 sec network overhead on each move with lichess-bot
