Chess Workshop

• White moves first. Take turns moving one piece. Keep your king safe: kings are never captured.
• Rooks follow rows and columns, bishops follow diagonals, queens do both. Knights jump in an L; kings move one square.
• Pawns move forward but capture diagonally. A pawn on its starting rank may move two empty squares. On its last rank, it must become a queen, rook, bishop or knight.
• Castling needs unmoved king and rook, an empty path and a king that is not in, crossing or entering check.
• En passant is available immediately after an adjacent pawn advances two squares, then expires.
• Checkmate wins. Stalemate draws. Look for checks, captures and your opponent's next move before choosing.

Three identical positions or 50 moves by each player without a pawn move or capture allow a draw claim. Five repetitions or 75 such moves draw automatically; checkmate takes priority. Bare kings, a lone bishop or knight, and bishops confined to one color also draw automatically.

This is untimed practice, without touch-move rules or a tournament arbiter. Rare blocked positions where no checkmate is possible are not automatically detected; two players can agree a draw. Hints and undo are learning aids.
