The tension is high after 8 of 40 games where Rybka leads with 5.0 to 3.0 (+2).

Hi Martin
What's wrong with Houdini in this match?
Greetings

Kurt,

Nothing is wrong (technically) but I must admit that Rybka is playing some fine chess.
It seems that the 4.1 update is very strong on long TC.

Houdini hasn't won more than one game and if it is going to win the match it needs
to start winning some more games soon.

Best,
Martin

Houdini does not like long time controls 
Parent - - By Rudolf Rohs Date 2011-04-15 11:04
Hi,

I am not sure that Houdini 1.5 don't like long time matches as Houdini won the previous match against Rybka 4.0 on the same time level.

When you see to the at the same time running match by Frank Quisinski there also Rybka 4.1 has a very good score against Houdini 1.5.
It seems that Rybka 4.1 is focussed on the style of Houdini 1.5.

The total score against all used engines in Franks tournament is not much better than for the 4.0. So f.e. Rybka 4.1 has a very bad result
against Ivanhoe 47C.

Best regards

Rudolf

A speculative but good explanation.

Hi Rudolf and the others,

now I saw it too.
Never look of these results in the still running SWCR tourney table!
Main topic for myself are the games and the table of ELO differences with game number x (so far messages 171 a-d so far).

For a bugfix version is 20 ELO more (Rypka 4.0 to 4.1) a lot.
But let us wait of more results.

Best
Frank

PS: Around for two - three weeks I made a little compare with Rybka 4.0 / 4.1 in different test position. I had seen that in endgame the analyses are more exactly. In endgames I saw an improvement and not a bugfix "only". But it could be random because I tested only 10 endgame position with long time analyzes. Not to see if I tested with 5 seconds per move.

After 18 of 40 games the score is:

Code:
N Engine         Pts    SB     Rybka 4.1    Houdini 1.5a

1 Rybka 4.1     10.0   80.00                + 4 = 12 - 2
2 Houdini 1.5a   8.0   80.00   + 2 = 12 - 4             


In the on-going game 19 Houdini is heading for a win which would bring
it to -1 and close the gap. The game is excellent btw (26...h4!).

Standings after 23 of 40 games:

Code:
N Engine          Pts     SB     Houdini 1.5a     Rybka 4.1   

1 Houdini 1.5a   12.0   132.00                  + 5 = 14 - 4
2 Rybka 4.1      11.0   132.00   + 4 = 14 - 5             


Houdini has played like a maniac the last few rounds, right now it seems unstoppable.
Parent - By Martin Thoresen Date 2011-04-21 22:15
Final standings:

Code:
N Engine         Pts    SB     Houdini 1.5a  Rybka 4.1   

1 Houdini 1.5a  22.0  396.00                 + 9 = 26 - 5
2 Rybka 4.1     18.0  396.00   + 5 = 26 - 9             


After an exciting start where Rybka took an early lead Houdini
dominated the later part of the match and successfully defended
its TCEC Champion title.

See you all in season 3!
