Checker play
With one man back, two bad things can happen to black after the loose hit on the ace point. He may be hit or he may not be hit.
This is another way of saying that the hit on the ace point is too commital in this position.
If white does not hit back, black must quickly cover the blot, or he will be haunted by blitzes and tactical strikes. But making the ace point takes away much of black's priming potential and the robustness of black position as a whole. Even in the bear-off, checkers on the ace point represent an accumulated wastage.
11/6 is the better non-hitting 5, because it does not strip the midpoint.

Cube action
Refering to the previous move of black, he must have felt desperate when he hit on the ace point. Now he passed with relief... The fact is that even this position is a take even at a 5 away 7 away score. The non-commital position without the acepoint hit was an easier take, of course.
I think Robertie discussed somewhere somewhat like the uncompromised by the loose hit position after the best five 11/6. Black's only asset so far is the OMB (one man back). If he makes an inside point, he may start to bother both white stragllers. I call these Robertie stacks, because I learned from him about the benefit of playing from stacks instead of mixing it up against the wind.
