Missed perpetual check
And you — how often have you allowed it?

What is it?
A missed perpetual check is a lost or clearly worse position where you had a run of checks the enemy king could never escape, but you kept playing on as usual. You threw away half a point that was still on the board.
How it happens
It mostly happens when you’re down material and demoralised: you look for a normal attacking plan instead of counting your checks. It also shows up when the enemy king is exposed or boxed in by its own pieces, and you chase material instead of aiming for a repetition.
How to avoid it
As soon as your position turns losing, switch your decision rule: list every check available, queen and knight first, and map the enemy king’s escape squares. If two checking squares feed each other and the king shuffles between two squares, the draw is there.

- When should I go for a perpetual check?
- When your position is objectively lost, or when you’ve given up material with no lasting compensation. As long as you can still play for a win, repeating costs you half a point rather than saving one.
- Which pieces deliver perpetual check most often?
- The queen manages it alone quite often, especially against a king with few escape squares. Queen and knight together are the deadliest pair, since the knight covers the squares the queen can’t reach from her checking square.
