Group is tied in the final of a tournament?

What if the group is tied in the final of a tournament? You replay the final? Perhaps add this to the FAQ list?

Yes, there will be a new round.

Tie-breaker round, in theory could be repeated forever if neither wins both games - I've had 3 tie-breaker rounds (with the same opponent of course) in one tournament.

Thanks! Wish me luck then, because I need to win one of the two games just to get a replay!

Hmmmm.....I wonder if someone could invent a penalty-shoot-out of chess?
