I did not measure the thinking time of GnuGo level 16, but it seems quite
long, and some games (at least 1, I don't remember) never finish after a lot
of hours. Perhaps it is just a bug :).
So I think using GnuGo level 8 is reliable (and for experiments much
faster).



If you have (or anyone else has) examples of .sgf-files with such
extra-ordinary long thinking times for a single move, I would be interested
in seeing them.

(Send them to me, to gnugo-devel-at-gnu.org, or attach them at
http://trac.gnugo.org/gnugo/ticket/160.)

My suspicion is that most of them are related to explosion of branching
factors in the local reading of ko fights - due to various reasons these are
not very well controlled in GNU Go.

I have such games. It was with a expermental version of Suzie, were Suzie 
played quite aggressive/over optimistic. Gnu-Go calculated very long, but won 
these games at the end completly
When Suzie plays sound and wins or looses only be a small margin, Gnu-Go plays 
also with level 16 relative fast.
I am currently in my private house in Austria, the games are on my computer in 
Germany (where I work currently during the week). I will send it on Monday.
