# Checkmate

For other uses of the word, see Checkmate (disambiguation).

Checkmate (frequently shortened to mate) is a situation in chess (and in other boardgames of the chaturanga family) in which one player cannot avoid their king being captured on the next move - it is a check from which there is no escape. A player who is checkmated loses the game. Delivering checkmate is the ultimate goal in chess (although not all games end in checkmate - often a player resigns before checkmate is administered, or the game may end in a draw in several ways).

It should be noted that the actual capture of the king is not played - the game ends as soon as a position arises in which the capture is unavoidable.

The fastest a player can cause a checkmate is 2 moves. This occurs in fool's mate when a player moves their kings bishop's pawn one or two squares and kings knight's pawn two squares, and their opponent moves their queen to the file of the opponent's king's rook (1. f3 e5 2. g4 Qh4# in algebraic notation).

If a player's king is threatened with capture, but that threat can be met, then the king is said to be in check (a check may be met by moving the king to a safe square, by interposing a piece between the king and the threatening piece (assuming the attacking piece is not directly next to the king and is also not a knight), or by capturing the threatening piece). If a player is not in check but has no legal move (that is, no move which does not allow their king to be captured), the result of the game is stalemate.

The term is an alteration or Hobson-Jobson of the Persian phrase "Shah Mat" which means, literally, "the King is dead."

Some common or notable mating patterns have names of their own. Apart from the aforementioned fool's mate, these include scholar's mate, smothered mate and the back rank mate.

Traditionally, when checkmate occurs (or is thought to be inevitable) one lays one's king down on its side to indicate that the game has ended.

Science kits, science lessons, science toys, maths toys, hobby kits, science games and books - these are some of many products that can help give your kid an edge in their science fair projects, and develop a tremendous interest in the study of science. When shopping for a science kit or other supplies, make sure that you carefully review the features and quality of the products. Compare prices by going to several online stores. Read product reviews online or refer to magazines.

Start by looking for your science kit review or science toy review. Compare prices but remember, Price \$ is not everything. Quality does matter.
