I'm talking about resigning a game which is part of a multi-point match with the cube.

I'm not saying a player should be let out a game where the other person has a chance to get maximum points from them. I am saying a player should be let out a game where the other person does not have a chance to get maximum points from them (for example, in a multi-point match with the cube where a player already has at least one piece removed, and therefore cannot possibly lose more than 1x the cube).
