In Response To: Perhaps Most Discussed Madison Play (Bill Riles)

For what it's worth, there's the rollout. I did actually learn something from this position - when you stumble across one of these fine positions, positions that rarely if ever occur, force yourself to look at all possible plays, even those that automatically appear ludicrous in your mind's eye. [13/7* 6/3 & the others for that matter]

The score (after 0 games) is: gnubg 0, user 0 (match to 1 point, post-Crawford play)

Move number 3: gnubg to play 63

gnubg	54
user	91
Position ID: 7bYBkQDfjwIGAA Match ID: MAEvAAAAAAAA

• gnubg moves 13/7* 5/2

Alert: unlucky roll! ( -0.571)
