Not sure whether I forgot to post the rollout or it disappears somewhere.

Leaving the anchor is the best move, a bit scary, but maximizing contact and there is still 2 entry points if hit (excluding 5-1)

Regardless the position of the cube, don't be coward because the Blue homeboard is a very strong permanent asset until the end of the battle in the outer boards.
