How to play

Two players share one board, White moving first. Click a piece of your own colour and the squares it can legally reach are marked, with squares holding an enemy piece marked differently from empty ones. Click one of them to move. Every piece follows its normal movement rule, including the pawn's two-square first move and its diagonal capture. This is a simplified engine: it does not detect check or checkmate, so a game is won by capturing the enemy king outright.

• Click your own piece — selects it and shows its legal destinations. The message below the board reports how many there are.
• Click a marked square — moves the piece there, taking any enemy piece that was standing on it.
• Click anywhere else — clears the selection.
• New Game button — sets the pieces back to their starting squares and gives White the move.

Scoring

There is no score and no material count. The game ends only when a king is captured, at which point the message names the winner. A pawn that reaches the far rank is promoted to a queen automatically, with no choice offered. Castling and en passant are not implemented, so the opening plays a little differently from a full chess program.

Tips

• Because check is not enforced, you can leave your king attacked without warning. Look at what your opponent's pieces reach before every move.
• The same gap works in your favour: watch for a direct route to the enemy king rather than building a slow mating net.
• Selecting a piece is free and shows its full move list, so use it to survey the position before committing.
• Pawns promote to a queen the moment they arrive, which makes a passed pawn on an open file a much faster threat here than usual.
