Leaving the joker seems unnecessary since you have such a stranglehold on the position anyway. That makes 15/10 forced and an ace left to play. We still would love to make the two point/be able to attack there if the opponent enters with a deuce so 8/7 is the logical ace. Even if the opponent should happen to enter with both this turn it is still a very easy position to clean up. If he doesn't, which he isn't likely to, we'll either hit loose/make the 2pt or bring our men in to the proper high points and have more ammo for making the 2pt next turn.
