Thanks for your report.
The question of UCT versus Alpha-Beta is not open any more in my
opinion. The current state of the art of Monte Carlo tree search is
about 500 Elo points stronger than the version of Crazy Stone you tested
against. Do you believe you can easily catch up with those 500 Elo
points ? Also, I am convinced that UCT has tremendous potential for
further improvement. I have improved Crazy Stone by about 50 Elo points
per day in the past 10 days (on 9x9. The improvement on 13x13 and 19x19
is much more). I am very confident that I can easily improve it further
very much.

The main point of my mail was: Search works (at least in 9x9) well. I think
we can agree on this point.
For the UCT v. Alpha-Beta question there is a simple proof of the pudding:
Sent us the latest/strongest version and we will try to beat it.
Suzie is so far a very propretiary system which runs only under GoAheads
GUI. And GoAhead does not support GTP. GnuGo is run with a hack. The matches
against Crazy-Stone are done by hand. Its Stefan Mertins version of watching
TV.
I am working currently on a modern C# based GUI which shall support also
GTP. But progress is due to my engagement by Siemens rather slow***. Once
this GUI exists we will be able to participate on KGS tournaments and other
programmers could get Suzie if they like.
*** I have also done almost nothing to improve the search, the main progress
is due to Peters intensive work on the evaluation.
