Gives directly the probability of winning the match
after Double/ Take and Automatic Redouble.
1.4707 divided by two = 0.73535.
What is the logic of using a more complicated
formula here that is known to produce the wrong answer?

Subject: Re: [Bug-gnubg] Use of Two-Sided
DB in matches
Whoa,
It may be that I am dead tired and
probably missing something. Can you give me the Gnubg ID (just the position)
for your stats below? Because we are not looking at the same position. And I
now see where all my confusion is coming from. Originally on BGO you posted
this:
http://www.bgonline.org/forums/webbbs_config.pl?noframes;read=47213
Now
since I dont have anyway of easily converting XBGids to Gnubg I decided to
use the GnubgID from the data you retrieved from Gnubg in this post:
http://www.bgonline.org/forums/webbbs_config.pl?noframes;read=47327
I
have been blindly assuming that the 2 position were equal. After you posted
below I realized they are different. In XBG you have the on roll person
opposite to what you have for GnuBG. I have been copying and pasting the
gnubgid out of this post all along. Its not the same.
However I just
discovered in this post:
http://www.bgonline.org/forums/webbbs_config.pl?noframes;read=47359
That
its the same as your XBG. Can you clarify which position we are looking at?
Right now, I am not analyzing the same one you are. I am confused.
Thanks
