Sameshi – a ~1200 Elo chess engine that fits within 2KBFeb 2026 · github.com · ▲230I made a chess engine today, and made it fit within 2KB. I used a variant of MinMax called Negamax, with alpha beta pruning. For the board representation I have used a 120-cell "mailbox". I managed to squeeze in checkmate/stalemate in there, after trimming out some edge cases.

The source is available here: https://github.com/arikwex/infernal-sigil NOTE: the current head of the main branch is at 13.6KB due to quality of life patches. The legit 13KB version is tagged in github. Useful hacks: - Using Roadroller (https://github.com/lifthrasiir/roadroller) for compression - Compressing the map data as grayscale PNG paired with some code generation. - Using procedural…
