In Response To: Crawford backgame - part 3 (Ian Dunstan)

The score is: Mradica 2, The Dice Man 8 (match to 9 points, Crawford game)

Move: The Dice Man to play 14

Mradica	136
The Dice Man	165
Position ID: 2G5TAFBmGwEDGw Match ID: 8IkwASAAQAAA

• The Dice Man moves 16/15*/11

Gnubg agrees with the experts, and I got this right too. Note, I forgot to change my default Gnubg settings, so this rollout plays 0-ply after the first 6 moves by each side.
