[Bug-gnubg] Beaver issue ?

[Massimiliano Maini]

Hi all,

from a post on BGonline forum:

Cube decision
Rollout cubeless equity +0,1830  
Cubeful equities:
1. Double, take         -0,1315  
2. Double, pass         +1,0000         +1,1315
3. No double                 -0,1732         -0,0417
Proper cube action: Double, beaver

As pointed out in a message of the thread:

"Probably I'm confused, but this looks a gnubg bug to me.

If double/take is -0.13, then double/beaver is -0.26. And if no double is -0.17, then this
isn't double/beaver, it's no-double/beaver. (It's double/take if beavers are not allowed.)"

I'm not sure if this is related to Item #15434: Wrong cube evaluations in games with beavers
on bug tracker ... I would say no since here the issue is not in the analysis but just in
the interpretation of the rollout results. If it's a separate issue, I can open a new item
(I may even try to ask for the sgf file).

MaX.
