White to play 5-2.

White moves from black’s 5 point to black’s 10 point, hitting, and from black’s 9 point to black’s 11 point. Here again, white makes a crucial error, in our opinion.

The 2 is vital. Following the practice of not hitting when you are defending against a back game, white does not hit twice — but he should have. It is a time to ensure that black does not make white’s bar point by rolling a 6-1, 6-2, or 5-2, a total of six shots. (He should not use 5-1 to hit, because the 2 point is too faluable.) It is a calculated risk, but we think white was in error here. If white secures his bar and establishes a prime, he has an excellent chance to contain his opponent’s men long enough so that black’s remaining forces will be well out of play. In other words, black’s other men will have been forced to move to the forward points in his inner board before white’s blockade breaks.
