A king cannot itself directly check the opposing king, since this would place the first king in check as well. A move of the king could expose the opposing king to a discovered check (and, rarely, checkmate) by another piece, however. In fast chess, depending on the rules in effect, placing or leaving one's king in check may result in immediate ...
In chess, a flight square or escape square is a safe square to which a piece, especially a king, [1] can move if it is threatened. Providing one's piece with flight squares can prevent the opponent from winning material or delivering checkmate .
The king (♔, ♚) is the most important piece in the game of chess. It may move to any adjoining square; it may also perform, in tandem with the rook , a special move called castling . If a player's king is threatened with capture, it is said to be in check , and the player must remove the threat of capture immediately.
After this move, White cannot prevent the black king escaping the b1–h7 diagonal. The black king can play up the g-file to g6 and the white king has no option but to follow with opposition on the e-file to at least e5, otherwise the black king can escape to the third perimeter at f5 or f6. 83...

In practice, this means that for each of the squares in the king's field, there is exactly one reason why the mated king cannot be moved to that square to escape check. [c] Some authors omit the detail that the mated king itself is attacked only once. [9] In his Dictionary of Modern Chess, Byrne J. Horton provided the following definition:
The triangle mate involves a queen, supported by a rook on the same file two squares away, delivering checkmate to a king that is either at the edge of the board or whose escape is blocked by a piece; the queen, rook, and king together form a triangular shape, hence the name of the mating pattern.
The possible ways to get out of check are: Move the king to a square where it is not in check. Capture the checking piece. Interpose a piece between the king and the opponent's threatening piece (block the check). [17] [18] [19] In informal games, it is customary to announce "check" when making a move that puts the opponent's king in check.
Checkmate (often shortened to mate) is any game position in chess and other chess-like games in which a player's king is in check (threatened with capture) and there is no possible escape. Checkmating the opponent wins the game. In chess, the king is never actually captured. The player loses as soon as the player's king is checkmated.
