In Response To: GS checkerplay (Chuck Bower)

GS makes a big difference as can be seen from these rollout results. At most scores (and $) 13/1* looks right.

The score (after 0 games) is: JellyFish 0, Player2 2 (match to 3 points, post-Crawford play)

Move number 5: Player2 to play 44

Pip counts: JellyFish 128, Player2 139
Position ID: Ys8NAyDaNsEAQw Match ID: UQlyAAAAEAAA
