In Response To: Bear-In Problem (Dave)

Only 1024 but with that it's close. If anyone wants the rollout to go further let me know. It's interesting that 18/11 still wins a few more games but 9/2 is at least as good a play. What's further interesting is that nothing occurred to me except 9/2 so clearly I did miss out on this other possibility. Any ideas on what it would take to keep the basic idea but where the 9/2 play would be inferior? I got "lucky" here but it's obvious to me now that there are other things I need to consider when playing these situations.

The score (after 0 games) is: gnubg 1, user 0 (match to 3 points)

Move number 7: user to play 43

user	97
