Perpetual Check
What it is
A perpetual check is a drawing resource where one side delivers an unbroken chain of checks that the enemy king can never escape, forcing a draw by repetition — invaluable when you would otherwise lose.
When to use it
Use it when you are worse or down material but the enemy king is exposed, and you have a queen or pieces that can shuttle between two checking squares forever.
How to use it
Find two (or more) squares from which you can keep checking the king with no way for it to hide or block permanently. Confirm the king cannot interpose or run, then repeat the checks to secure the half point.
