Yes, Largo. I have a version of this I can put on CGOS (and other's can too so that we can check each other for bugs). I tried using Largo as a component of a playout policy with no success.

I will also put a version of MoGo up (the version that was released to the public).

It was Doug Larson's idea.  Something like:
Pull a single stone out of Atari once
Play in a liberty of the group with fewest liberties that has 5 or fewer
liberties
Play random

I also am thinking about building a really fast and weak playing bot.
Something that is similar to the rule based program someone suggested
to
you, but with a few simple 3x3 patterns to supplement it.    Do you
remember what we called that program?     It played by simple rules
such
as attacking the group with the least liberties, etc.    We names it
somewhat after the person who suggested the idea.

I think there are two reasons there are not more programs on 19x19
CGOS:
1) The anchor, Gnugo, is quite strong, Many Faces 12 is stronger, and
CrazyStone is much stronger.  Since the programs playing are so
strong, it
is demoralizing for a new program to lose so often.  Without weaker
competition, it is hard to get accurate ratings for new, weaker
programs.
2) The rounds take almost an hour, so it takes much too long to get
enough
games to see how your program is doing.  In my local testing, I use
10 or 15
minutes per side.  I like to see 50 to 100 test games get any
confidence
that a new version is stronger.  I prefer to get a test run complete
in
under a day.

I propose the following changes:

I'll put up 3 weaker versions of Many Faces 12, so there is
competition at
lower ratings.  These versions are quite fast, using only a few
seconds for
a full game.  This will provide some stable opponents for the weaker
programs.

I think the time limits for CGOS19x19 should be reduced to 10 or 15
minutes
per side.  This is enough to test programs, and it's still a
reasonable time
limit for games against people.  Since programs that search scale
with
additional time, the relative ratings of these programs should be
similar at
10 minutes per game and 30 minutes per game.
