It is ranked among the best in the world (estimated power of 4039 Elo for v.16, ranked 1st out of 106 candidates in the "CCRL 40/2 - All engines (best versions only)" of February 28, 2024), communicating with the UCI protocol (the most common protocols are CECP aka Winboard/Xboard, and UCI). Its algorithm is "alpha-beta pruning". Another superb gift to the Open Source community!

An elegant combination, allowing you to play alone (AI at adjustable level) or with a friend (in hotseat), with undo/redo, save/read games in pgn format or copy/paste FEN positions, launch a game analysis, test other AI, ... Excellent!

I hacked together a simple #ChessEngine (Alpha Move) in #Python. The "algorithm" has entirely been stolen from #xkcd3045. It uses UCI so you can let it play against other engines in your favorite chess program! Having it play against itself is also an option of course but predictably it results in an infinite loop.

Spent today refining the board representation in my chess engine and fixing some bugs in move generation. Added a new test suite in Zig and updated the build process to run it smoothly. Still a few issues with perft results, but overall making steady progress. On to more debugging tomorrow! strydr.net/articles/devlog-0xB

Just published a deep dive into using 32-bit integers to encode chess moves in my chess engine, Kirin! By packing source, target, piece, flags, and more into a single int, we boost efficiency and performance.

Screenshot of the Banksia chess GUI application showcasing an engine-to-engine game in progress, featuring Coding Adventure 2.0 and Googleplex Starthinker 1.6 with example engine info output, including depth, seldepth, node stats, score estimation, and pv lines (Coding Adventure engine is clearly delusional about its board advantage).
