I think, therefore I mate.

Hobby-level, bitboard-representation chess engine that is in active development stage, hence many features are still missing.

Roadmap

• Get this thing to play reasonable (although not really smart) chess!
• Debug & fix forced mate encoding and printing
• Self-playing and evaluation constants tuning (Texel)
• Opening book
• Endgame database
• Pondering

Building

git clone https://github.com/kitrofimov/chessica
