Tim's rollout of his variant is shown above. My variants key off of his.

In my first variant (below), White owns her 11pt instead of her 9pt. This easily swings Blue's best play. All good ways that White might have been able to play a 6 (i.e., 23/17*, 21/15, 15/9, and 13/7*) have been denied.

In my second variant, one of Blue's 6pt checkers is nudged back to his 7pt. This change has a smaller effect but still wipes out 22/18 6/5's edge and gives POH (8/4* 5/4) a slight lead.
