We want the gammon, and he's got a blot in his homeboard and only two points made vs. our 5.  HIT!!!.
As for where to play the one, I'd go for 22/21 - unless he rolls 11 he won't want to hit us, and he'll hit us with 11 whether we play 22/21 or 4/3.  So I say spread the runners around and diversify leaping numbers.

22/21 6/1*

Sorry that you didn't get to dance.  Maybe there'll be another opportunity for you to show your moves on the dance floor.

In the meantime, we can peruse this rollout.  And since I now have an up to date sgf file and there arent' any cube dceisions lurking I'll rollout some interesting positions and post under the relevant move thread.

A difference of .1 EMG is generally considered to be the threshold for a whopper.  Here we have a difference of .094, which is probably about a pickle shy of a whopper, but close enough. 

In terms of match winning chances, the difference is about 1.45% - not all that much on it's own, but if you make a dozen or so of these over the course of the match, you're giving up a lot of equity.
