Sorry, not solved. In the gui it still freezes, at command line I see
the last position of the match (but vice versa) and it says (no game).

Ok, after also re-making sgfp.c it works again. Does anyone understand
what was going on here with the parsing?

Where did you hide that code? I coudn't find anything in cvs, but maybe
I'm blind today.

Afaik this problem only occurs when you use odd truncation and even
plies or vice versa (according to a statement by Daniel Murphy). I did a
lot of truncated rollouts of positions and few of them also with 2ply
full but didn't experience any substantial "odds" besides those where
truncated _and_ full rollouts showed that 2ply eval was wrong.

[Bug-gnubg] bug: current binary freezes when opening a sgf file

[Achim Mueller]

Hi,

again SuSE-10.1, todays snapshot, I also rebuilt sgfl.c.

I can import matches analyse and save them as sgf files, but when I open
a sgf file (old or made with this binary) the gzi freezes.

SSE supported and available.

At the command line I'm able to use ctrl-d for stopping,the gui has to
be killed.

[Bug-gnubg] Re: Rollout presets

[bower]

Don't we know that truncated rollouts for cube decisions are 
susceptible to considerable evaluation systematic uncertainty?

(I never trust a truncated rollout on a cube decision, but I'm
pretty hardcore.  :)  By making that one of the default options
does it build a false sense of security for the user who may
not know this?
