playBunny: If the scoring of the game is such that gammon or not doesn't matter (for instance because the dice is not being used) playing on to see whether you could avoid the gammon doesn't make much sense. Your play might be to avoid th e gammon, but since gammon or not doesn't matter, your opponents play will not take gammon considerations into account. With other words, you would be both playing a different game. Even if you avoid the gammon, it does not mean you would have avoided the gammon if the gammon had mattered (because your opponent might have made different moves).
