Friday 17.00 gmt?
A long time to wait!
Anyway, maybe Houdini was tuned against Rybka 4, so even if it does do very well, i wonder if it might not be as honest as in the recent tcec tournament in which it must not have been tuned against all of them in the same way, and in that tournament, Houdini, JUST ABOUT came first with
24 to Rybkas 23.

There is no data that suggests that Houdini 1.5 scores particularly well against Rybka 4.
Compare:
- In the TCEC Division I Houdini scored 9.5/14 (+5 =9 -0) and Rybka scored 8.5/14 (+6 =5 -3), which translates to a TPR difference of nearly +50 Elo in favor of Houdini.
- In the long TC matches between the two engines as reported by Paul Watson, Ingo Bauer, Sedat Canbaz and Pal Larkin, the results varied between +30 and +70 Elo difference in favor of Houdini.

Looking forward to the Elite Match, hopefully we'll see some real fighting chess!

For people involved in betting :

After N games the probability that Houdini leads is

100% - 50%*(0.89^(N^0.82))

After 6 games it's 70%, after 10 games 77%, after 20 87%, and after all 40 games 95%.

Rybka has 5% to win the Elite Match.
Enjoy the Games!

For those that is wondering what is happening during game 14, well:

The webhost is upgrading their storage systems and this started around 00:00 CET and is expected to last 2-3 hours.

Unfortunately there's nothing I can do about that.

In any case, 2 hours have passed now so you can expect the website to be back very soon.

Best,
Martin

I appologise for not having found this thread at one time when i was looking for it, and i am thankful for being redirected. But i am not saying this on the other thread i started, so as not to bring it to the top. And indeed, that one is a superflous thread and can be deleted.

First Houdini seems to crash Rybka, but now only boring draws...

In this kind of high-level match you can expect about 70% draws, it's quite inevitable but not necessarily boring.

Try game 17, which is a draw but one of the most amazing games I've ever seen.
Houdini sacrifices several pawns in a difficult position, at some point Rybka is 4 (FOUR) pawns ahead and Houdini plays the quiet move 36...Kh8!
