Three-Check Chess

Check the enemy king three times and you win.

Three-Check is the easiest variant to teach a chess player — one sentence of new rules — and it changes evaluation completely. Checks that a strong player would dismiss as pointless become progress on a scoreboard.

Three-Check Chess rules

  1. 01

    All standard chess rules apply.

  2. 02

    A counter tracks how many times each side has given check.

  3. 03

    The third check you deliver wins the game immediately.

  4. 04

    Double check counts as one check, not two.

  5. 05

    Checkmate still wins at any point.

How it changes your play

Sacrifices for a single check are frequently sound: a piece for one third of the win condition is a real price.

Defence means removing checking squares, not just defending material. Advancing the h-pawn to stop a bishop check is a normal opening move here.

Questions about Three-Check Chess

Does a discovered double check count twice?
No. Any single move that gives check adds exactly one to your counter, regardless of how many pieces attack the king.
