Hi all, Hi Achim, Hi NArdy, Hi Adrian,

on http://www.heise.de/newsticker/meldung/91305 (german!) I read that
gnubg again became runner up and Frank (BGBlitz) won the title for the
third time now?

Yes, indeed ;)

Congrats to Frank (he's reading this list also).
Thanks a lot ;)

Any chance to get a
small report or the matches?

The matches in HTML against GnuBG are here :


and here


As matfiles they are here: http://www.bgblitz.com/download/ amsterdam_2007.zip

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.

>However, having won the Silver, we're definitely going to have to find
>someone in the community to go to Beijing next year to get the gold 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.
