Kamikaze 6/5 4/1* did best in Chuck's 2-ply rollout. That play's equity was -1.2772. It should be worse. The idea behind the play is to force Opponent to hit, get more checkers sent back, and eventually hit and snake a prime home. In the rollout, the play works -- too well. On the next roll (or two) Gnubg 2-ply hits even when it doesn't have to.
White rolls 6-4: 2-ply plays bar/21*/15 but should play bar/15. Error = 0.1442 * 2/36 = 0.00801.
The score (after 0 games) is: White 2, Blue 0 (match to 13 points)
Move number 6: White to play 64
