Thanks for your letter. I'm cc'ing my reply to the GNU Go list.

About the games, only if you see a game that you think
is really interesting. GNU Go plays constantly on NNGS and
have more of this sort of tuning material than we can
deal with.

Which gtp client are you referring to? I suppose Tristan
Cazenave's gtpclient but there is also Gunnar's
gnugoclient. It might be good to see your modifications.

I don't know the difference in strength but there is a
clear difference in accuracy. Since GNU Go's main advantage
against (weak) humans is that although it is strategically
stupid it can sometimes outcalculate them, I imagine this
has a big impact. A lot of things are turned off below
level 8. Level 8 should give respectable play, for example
definitely stronger than GNU Go 2.6.

Subjective opinion has it that 3.1.11 is slower than 3.0.0.

Wolfgang Manner posted some changes to GNU Go 3.0 and to
Jago which allow you to use undo when using Jago. These
are at  It
is unlikely they work with 3.1.11. They haven't been
much tested except by him so we'd be interested in a
review of them.

You probably should ask Rene Grothmann if he's seen this.
Does anything in particular seem to trigger it? (Ko or
