Nice and fast. Especially like the "Check" animation. But no detection of stalemate condition in endgame. Otherwise, great to see a WASM chess engine ;)

thanks, yeah havent implemented stalemate, and the ai is a bit crufty. funny to see you call it fast; with -O3, which is whats online, it takes up to ten secs and when enabling debug symbols, it takes millenia, likely because my vector implementation is relatively slow
