10 Giving check

10.1 Tutorial

If a piece attacks the king, it gives check.

You have to react to a check because the king must not be taken. There are three possible ways to get out of check:
  • move the king away
  • take the piece which is giving check
  • move one of your own pieces to block the check (not possible when the check is by a knight)
If you cannot get out of check the king is (check)mated and the game is lost.

10.2 Exercises

Move directly on the board to input a solution. Either click first on the start square and then on the target square. Or click on the piece, hold on to it, move it tot he target square and let go of it. The button ‘Left arrow’ takes back the move.

If one side keeps on giving check and the other side's king cannot escape the checks, we call that perpetual check. Perpetual check is a good defebsive option if you are in a bad position and want to force a draw. If a position is repeated three times the game is drawn.

You react to a check by moving the king away, by interposing a piece or by capturing. If none of these work, the king is checkmated and the game is finished. Unnecessary checks in the opening achieve nothing.
