Stick's wild play rolled out at GS

Paul Weaver recently posted a wild play by Stick at backgammon save. Just out of curiosity, I decided to roll out the play at gammon save instead. As you can see below, double-hitting (which is hugely right at most match scores) is at best barely correct at gammon save. The cubeless backgammon rate is not entirely negligible either for this position.

The score (after 0 games) is: Stephan 0, Stick 2 (match to 4 points)

Move number 4: Stick to play 31

Stephan	88
Stick	83
