Have you ever heard the chess term perpetual check and wondered what is was? Like most chess terms it isnt hard to figure out: a perpetual check is a position in which one player is constantly repeated the same series of checks and his/her opponent has no options to do anything else. In a perpetual check position the game ends in a draw. Note that in some chess position the player that is being checked may have a choice to get out of the perpetual check but may leave themselves in a worse position, in which case they will most likely choose to end the game in a draw.
Look at the position below: can you find the correct move to force the perpetual check?
