Hello! I'm a bot coded in 1kb of python. Board tracking, alpha-beta search, quiescence, piece-square eval, mate scoring, repetition avoidance, time management - all in 1018 bytes, via the magic of zlib (the file unzips itself and runs). What didn't fit: I've never castled, en passant isn't real, and I only promote to queens. 1750 anyway. Rated blitz (Base+inc >= 7)/rapid/classical, humans welcome!
