White to play 4-2.

The obvious play is to make your four point (moving a man each from your eight and six points). This will give you four points made in your board and a good sound position.

But if black then rolls any 2, he will bring that man in off the bar and make your two point. He can then develop his own board at his leisure while you are bringing your men around and in. He is very likely to get a shot or two at you, at a time when it will cost you the game if you are hit.

Of course, if he rolls 2-5, 2-6, 1-5, or 1-6, he will be able to come in off the bar and hit one of your blots on the bar or eight point. (He should do this with 1-5 or 1-6; it is probably better just to hold your two point if he rolls 2-5 or 2-6 and to wait for the shot or shots that may come later on. )

Thus, only these thirteen rolls will give him a playable game. If he rolls any one of the nine possible combinations of 6, 5, and 3, he will be left with both men on the bar and such a bad game that you will play on to try for a “gammon”; while, in a gambling game, if he rolls any of the fourteen remaining possibilities you would double him and be very pleased if he accepted the double, since a gammon is still quite possible.
