playBunny: Just to throw my opinion in, I do not think that the implementation is incorrect just because other sites does it differently - I actually think how Fencer does it makes it easier for users not to try to cheat others.

I know on DailyGammon, some will offer a single resign for less points then what they will probable lose to newer users in the hopes of cheating people out of points.

How it is here, it automaticly looks at the "worse case" of how many points you could lose (gammon, backgammon). If you are so far behind that you are in the backgammon position, it would be silly for the other person to accept anything less then that. And if you are close to getting one of your own men off, then it only takes a few more moves then offer your resign for the single points.

(hence, as a more advanced gammon player, I like how dailygammon does it since it allows users to have more control on what is offered - but at the same time, some of the things that dailygammon does "scares" away newer gammon players, which is why I personally like how BrainKing does it.)
