There may be up to three possible ways to get a king out of a single check on the following move:
- Capturing the checking piece, with either the king or another piece. If the checking piece is on a square next to the king, the king can capture the piece if the king does not move into a new check, i.e. if the piece is not protected by another enemy piece.
- Moving the king to an adjacent square where it will not be in check. The king is not allowed to castle when it is in check. The king may capture an enemy piece in a move to get out of check, as long as the piece is not protected.
- Blocking the check. This will only work if the checking piece is a queen, rook or bishop and there is at least one empty square in the line between this checking piece and the checked king. Blocking a check is done by moving a piece (from the checked king's army) to a square in line in between the checking piece and the checked king. (The blocking piece is then absolutely pinned to the king by the attacking piece, until it is unpinned.) (Polgar & Truong 2005:32,103).
In the position in the first diagram, White can get out of check by three methods:
- The move Nxa2, capturing the attacking piece
- Moving the king to any unattacked square (marked with "x"), i.e. Kd6, Ke5, or Ke7.
- Blocking the check by the move Rc4 or Nd5.

If a king is placed in double check, the king must get out of both checks on the following move. Since it is impossible to capture both checking pieces or block both lines of attack in a single move, a double check can be escaped only by moving the king out of check. The king may, however, capture one of the checking pieces in the process, if that piece is adjacent to the king and not protected by another piece.
If none of these possibilities can get the king out of check, then it is checkmated and the game is lost by the player being checkmated.

Famous quotes containing the word check:
“cried as he died, fearing at last the spheres’
Last sound, the world going out without a breath:
Too proud to cry, too frail to check the tears,
And caught between two nights, blindness and death.”
—Dylan Thomas (1914–1953)
