Step Seven: Know The Difference<bR> Between Check And Checkmate

This is the difference between threatening to win and actually winning the game.

When a king is threatened with capture, the player who threatens the king makes this known by saying "check."
To avoid capture, the king may be moved out of check, the threatening piece may be captured, or a piece may be moved between the king and the checking piece to effectively block check.
If there is no way out of check, "checkmate" is called and the game is over.
The king may never move into check.

Chess etiquette requires that the king is not removed from the board. Rather, the king is laid down sideways on the board.
