Posting a position and rollout where Ray F trailing at GG vs Richard M creatively decided to try to pick up a 3rd checker. As the rollout shows, it is much TCTC. Note that GNU evals favor trying for the 3rd checker by a very small ammount.

The score (after 0 games) is: gnubg 0, user 2 (match to 4 points)

Move number 6: gnubg to play 46

Pip counts: gnubg 92, user 76
