Black to play 1-1.

Bring two men from black’s 8 point to black’s 7, or bar point, and two men from black’s 6 point to black’s 5 point. This invaluable roll establishes an immediate three-point block incorporating two important points — black’s bar point and 5 point. There is no better way of playing this best of all opening rolls.
