Maybe GNU Go 3.7.10 is _the_ good anchor player for 19x19:
- everybody use it at home for tests
- at level 10 it is fast, level 8 is slightly weaker but really much faster
- it is one of the strongest program available
- it is GPL

Yes, that's true.  When the server first goes up,  there
are no rated players and the games of 2 unrated players
have no affect on each other.It takes a long time
for ratings to converge in this case.

When I started the 9x9 server I seeded it before opening
it up to everyone.   I played a few hundred matches between
the anchor, gnugo and other players I had access to so
that there would be reasonable rating pool to start
with.

It's actually not a big problem if you pick a default
rating that is close to the average - unfortunately
you don't know what the average will be in advance!

I will probably make some stable and common version
of gnugo be the anchor for 19x19.   If others want to
run an instance of it I can set them up as anchors
too - I just need to know the names of any bots set up
to be anchors.  

I'll put up a 19x19 version tomorrow on boardspace at
30 minutes per game.

I figured that a credible anchor player for 19x19 might
need a lot of cycles, and need to play a lot of games
at first, so spreading the load would be a good idea.

Are you saying that you believe there should be a lot of
anchor players?   If so 

  1. If there are too many, it decreases the variety, you might
 be playing this single opponent a lot more.

  2. I think a single anchor works.  

Having said that,  I originally intended for there to be
a couple of FatMan clones playing (as anchors) on other
peoples computers.That would take the pressure off of
me to always keep FatMan running.   You wouldn't have to
run it all the time, just hopefully a lot of the time.

I suggest that it would be more convenient for everyone
if various sizes of cgos all ran on the same server.  If
you want to donate horsepower to the project, a good use
of the resource would be to run "anchorman" type clients.
