The games were on a pretty high level with several turnarounds and a  
lot of interesting games. The first match was a little lopsided as  
you see at the score (16-4) with only 7 games. The 2nd game was much  
closer and more exiting. (15-11 with 14 games).
Nardy run both through the analyzer with rollouts at the critical  
moves. IIRC in the 2nd match BGB got 2040 although there were 2 moves  
that looked a little weired. The first match had 2031, but the  
rollouts were still going on so the final result might be higher  
(Nardy told me that a lot of moves flagged as non optimal turned out  
to be correct in the rollouts)
.
@Nardy: Is the rollout ready now? Cn you send me a copy of the files?  
And the files GnuBG -McGammon so I have a complete set to put on my  
website.

All in all we had a very good weekend and due to Nardys sparkling  
humor we had really a lot laughs. (And attending a live tournament at  
Saturday evening at the Amsterdam BG Club was an extra bonus)

McGammon used a MonteCarlo approach. That workes in Go extrenely well  
and pushed Go-programs further.
With only a little rule based knowledge McGammon failed and it didn't  
won a single game. nevertheless I regard the approach as good and  
they might come  up with something better in a year or two. At least  
a new competitor is always a good thing.

back...
Oh yeah, Beijing. I'm sure I wont attend physically (too far, too  
expensive), but maybe we can get an local operator.....

I will have some pages on my website ready at the end of the week  
with some pictures.
