How to Play Chess
- Click a white piece to select it — valid squares are highlighted with dots.
- Click a highlighted square to move. Captures are shown with a red border.
- The AI plays Black and responds automatically after your move.
- Pawn promotion: when a pawn reaches the last rank a dialog lets you choose Q, R, B or N.
Tips & Strategy
- Control the centre with pawns on e4/d4 early — it gives your pieces more room.
- Castle early to keep your king safe and connect your rooks.
- Knights are tricky to use but strong in closed positions; bishops shine on open diagonals.
