Black to play 5-1.

After 5/off, if black moves his 1 from his 5 point to his 4 point, subsequent rolls of double 4’s or a 5-4 will leave a single shot (blot), and the horror roll of 6-5 will leave a double shot.

If, however, black moves his 1 from his 3 point to his 2 point, he has broken the cardinal rule of keeping his high men even and has made himself vulnerable to the potentially disastrous rolls of 6-5, 5-4, 5-3, 5-1, and double 6’s, or four extra single shots, but no double shots.

Which is correct? Against White’s prime we would move down from the 5 to the 4 point, risking a double shot.
