ArtfulDodger: The maximise-dice-usage rule hasn't been implemented (but this is acknowledged to be a bug).

In our game wayney was able to move a single man with a single dice value which allowed him to stack all three men safely on one point. Further movement off the stack, using the other dice value, was blocked by my men. He should have been required to use both dice values which would have meant splitting the two that were already stacked, leaving me a spread of blots to hit. Subsequent dice rolls showed that I would have hit two of those blots but as a result of his illegal move he was able to make a game winning block on his ace point.

The rule is also part of standard backgammon and is probably needs to be addressed there as well. I expect that it's on Fencer's plate as he says on the Features requests board that "Pro backgammon (with doubling cube)" is in development.
