Hrqls: Basically, I think that if you are an odd number of points away from winning a match, i.e. having 2 points in a 7 point match, you wait to double. Theoretically, your opponent should accept anyway, unless he fears a gammon. But you could get a drop that will help you have to play one less full game. On the other hand, it could hurt because you don't allow yourself to win the game with a gammon.
