Release a challenge (challenger)
The challenger can release an accepted challenge from the 5th day after it was accepted. No reason is needed. The ladder does not change and there is no result for either player.
Release your challenge
Releasing ends the challenge. The ladder does not change and there is no result for either of you. You are both free to challenge or be challenged again.
If you have played, do not use this. The winner reports the score under Actions.
