There seems to be a problem regarding the Jacoby rule. Using the xgid from
http://www.bgonline.org/forums/webbbs_config.pl?noframes;read=71394
which is a money session with Jacoby :

(No game) show jacoby
This money session is play with the Jacoby rule. Default is:
Money sessions are played with the Jacoby rule.
(No game) set xgid XGID=-b----E-C---eE---b-d-b--B-:0:0:1:46:0:0:3:0:10
...
Setting GNUBG id mGfwATDgc/ABMA:cAkaAAAAAAAA
(Black) show jacoby
This money session is play without the Jacoby rule. Default is:
Money sessions are played without the Jacoby rule.

The setting for Jacoby is wrong, but there may be a deeper problem. My 
understanding was that the status of the Jacoby rule is not included in 
gnubg's matchid. That would imply you would have to either set the 
instance's default or not import the setting. Either choice being 
potentially treacherous.

On the other hand, the output : "This money session ... Default is ..." 
somehow suggests there could be some way to set jacoby for the current 
session without changing the default.

Maybe the Crawford bit from the matchid could be used for Jacoby if the 
match length is zero, but that probably would have implications elsewhere 
in the code.

Another minor glitch ; there is something like "nCube 1 fCubeOwner -1" 
displayed ; probably a debugging print left over.
