While all the top plays are close enough that one can't really go wrong, I was shocked to see that hitting was best. I added 9/8 in the rollout though it was never a play I personally considered OtB. We don't normally break a six prime unless we are (virtually) forced to. Making the 5pt in some manner is correct at dmp by just over 1% but for money the extra gammons of the third checker back more than compensate.

On XGR+ and XGR++ hitting is correct by ~.040.

My wild ass post mortem explanation goes something like this...obviously escaping the back checker is a huge priority but what we may not realize is that if we escape it (a lot easier to do after hitting) that at some point we will make either the 5pt or the 3pt cleanly. To bring this position home we don't need to make them both, and in that respect the made 3pt, which is easier to make, would likely be better to bear off against the opp's 23pt anchor.
