| Black to play 4-3. |
Most players are taught that in situations of the back game’s aftermath, they should diversify their men in order to give them a broader base of attack. But unless a block is established somewhere, white’s two men on his 4 point are immune to any black assault.
The correct play is to move the two men from white’s 7 and 8 points up to form a block on white’s 11 point. By doing this, black is, in fact, deviously attacking those men. Of course, black could block double 6’s, double 5’s, and double 4’s (although double5’s would be to black’s advantage, since it would leave two blots; moreover, with double 4’s, black is still a favorite to hit).
Therefore, by blocking white’s 7, black has made a more practical and far more imaginative play. Now any roll of white’s totaling 7 will force him to break the block on his 4 point. It is 5 to 1 against that white will roll a 7, but if he does, black can double and white should drop
