Blue to play 32

Leo's position is copied above except with direction and colors reversed. (With bgonline diagrams, I don't know of a way to put White on the near side or the inner board on the right.)

In Leo's (1296-trial) rollout, 8/6 8/5 is best, 13/8 is -.056, and 6/1 is -.064.

Let's bring another couple of plays into contention. In the variant below, the opponent's two 4pt checkers are moved to her 3pt. If you would have made either of the top two plays with 32 in the position below, bravo!
