The ideal way to end a game is when you are reducing your opponent to three men you have two ways to make another triplet. That way when your opponent with only three men can move anywhere on the board to block your making a triplet can only block one of your opportunities to make that triplet. You can accomplish this by resisting the move to make that move to reduce your opponent to three men while you set up your two opportunities to make that last triplet to reduce your opponent to two men.
