||White to play 6-4.|
Position 88 shows the other situation when you should hit two blots: you are working on a gammon.
You roll 6-4. You must use the 6 to hit his blot on your two point. How should you play the 4?
You can move a man from your eight point to your four point. In this case if black rolls a 2, he comes in, hitting your blot; if he rolls an ace, he makes his one point. In this latter case you are then very unlikely to be able to win a gammon, since he will hold that point indefinitely while moving his other men around the board toward home. H may even win the game at the finish if you have to expose a blot and he hits it. In the other case he has an excellent chance to make either your one or two point, with the same end result.
Your better play is to use the 4 to hit the man on your one point. This will put two of his men on the bar while you will have men exposed on your one and two points. If he rolls double 2 or 1, he will succeed in making a point in his board, but his position will still be very bad. If he rolls 2-1, he will also be likely to avert gammon. But if he rolls anything else, you are almost surely going to gammon him.
