Add an option to surrender from round robins. You may decide you don't like the template or you don't have time for a large round robin.

It could also work with normal tournaments to not decrease win rate. Unless it is a team game where both have to surrender. Joining and surrendering tournament is not big problem if not abused. It happens in official competitions.


Another valid reason is that you realize you are bad or the worst player in robin. You lose a lot so just want to surrender.
