Resigning in a 3-player game is a serious problem, though. I think the rule that is currently stated is very unsatisfactory. In fact most games are expected to enter a phase where one of the players has no hope at all to win, and would likely lose interest at that point. If one of the players was obviously winning, resegnation at that point, resulting in a 3/4-3/4-0 score, would rob him of the deserved victory. Preferably resignation of one of the players would not disturb the balance of power between the other two, and desiding upon a result immediately would almost always do that.
