		White is Player 2 score: 1 pip: 137 2 point match Crawford pip: 129 score: 0 Blue is Player 1

After Blue makes his best Gammon Save play of S, White will hit with only 13 numbers

After the Gammon Save rollout, I said:

"Blue extricates his third back checker, leaves only one blot (instead of two) and risks 13 shots instead of 30 (all numbers except 63 62 66 22). These are considerations of elevated importance at Gammon Save."

What I meant was that if (instead of S, diagrammed above) Blue plays B as diagrammed below (which is second best but –.047), he will get hit with 30 numbers at this score. However, it is actually only 28 numbers. I had failed to notice/visualize that if White rolls 61, she has the even better play of escaping the prime with R (Run, 24/17).

After Blue erroneously plays B, White will hit with 28 numbers (all but 63 62 66 22 61)
