**Show HN: Sameshi – a ~1200 Elo chess engine that fits within 2KB**

I 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.I am a great fan of demoscene (computer art subculture) since middle school, and hence it was a ritual i had to perform.For estimating the Elo, I measured 240 automated games against Stockfish Elo levels (1320 to 1600) under fixed depth-5 and some constrained rules, using equal color distribution.Then converted pooled win/draw/loss scores to Elo through some standard logistic formula with binomial 95% confidence interval.
