not an April Fool position

In Response To: not an April Fool position (Chuck Bower)

I just happened to roll out this modified position. Even though White's distribution is weaker than in the original position, Blue's redouble is marginal at best. The take is ofc huge. So it is straight forward to say it is a no-redouble in the original position. Another point which occurs to me regarding this position is that, one should always consider gammons won and gammons lost! Normally I consider only one of them. And someone please check my roll-out settings and tell me, if they are OK, the way I have them.

The score (after 0 games) is: White 0, Blue 0

Move number 4: Blue on roll, cube decision?

White	71
Blue	112
