Quick reference
- Host plays White (moves first), guest plays Black.
- Castling: click your king and select the destination square (king moves 2 squares toward the rook).
- En passant: capture an opposing pawn that just made a 2-square advance, on the square it skipped.
- Promotion: pawns reaching the back rank auto-promote to a queen (per-game promotion picker coming later).
- Win by checkmate — opponent's king can't escape capture. Stalemate = draw.
