Perpetual check

In the game of chess, perpetual check is a special case of draw by repetition, in which one player forces the repetition by a repeated series of checks. See rules of chess for details of draw by repetition.

Perpetual check can also occur in other chess-like games, although the rules relating to it may be different. For example, giving perpetual check is not allowed in shogi.
