Rollout and request for explanation.

In Response To: You don't want to roll 44... (David Levy)

I survived the first hurdle, entering B/21 and shifting points. 5/1*(2). I then played 8/4 and was shocked to discover how much better is 6/2. I'm still looking for explanation as to why that is so much stronger. Slotting at the front of a prime is a frequent theme in prime versus prime, but when we are blitzing, as here, it seems a bit rich--even when we are holding the point six pips away.

The "priming" play of B/21 6/2(2) 8/4 is so very bad, that even the berserko play of B/21 6/2(2) 5/1* came out better.
