Result Mainz Chess960 qualifier: 1) Sjeng 2) Rybka 3) Ikarus

[kranium]

Oh yes...

congratulations Gian-Carlo...

this is a great result for Sjeng...
very impressive, and against Rybka (who would be the favorite, if i'm not mistaken)...!
wow...

Yes great result but why was Rybka in the pre-lim when it is already invited to Mainz?!

good question...
i can only speculate here.

in any event it eliminated Toga!?

[swami]

Being ahead of Rybka is always a great result - Congrats Gian Carlo!

Toga 960 is buggy.
Toga CMLX is not buggy under ChessGUI (Chess960).

What's about Glaurung and Fritz?

I suspect they were no shows. Be interesting to see what would happen if Toga had qualified. 1) Is Toga allowed to enter? 2) who is is the programmer of Toga who must attend?

As far as I understand the rules it's allowed to enter. One of the programmers would have to show up to be eligible to play in Mainz. (I presume not all must be - I didn't see Larry Kaufman in Mainz last time)

[Gian-Carlo Pascutto]

I thought this was supposed to be a 2 day event? With only 2 weeks notice I had to work tomorrow(Sunday) but if I had known it was only a 1 day event possibly could have entered Hiarcs today.

The tiebreaks would have been today. But as you see from the result, none were necessary, so there are no more games today.

Last year there was one on Sunday between me and Naum for the prize money (which Naum won).

However not sure why I should have to play Rybka in this prelim - and would want to know that the Toga at least complied with GPL.

ICC allows any member to enter, but only those entries where the programmer confirms he will be in Mainz are eligible to qualify. The Rybka that joined here obviously wasn't eligible because it was not Vasik nor someone from his team.

GPL only covers distribution of code. Nothing was distributed here, so the Toga that played is *always* GPL compliant. (I'm not really happy about that either, but that's what the license says)

[Gian-Carlo Pascutto]

Huh, I always thought all of them did, because other Fabien things like PolyGlot are Chess960 compatible.

The Toga version was "1.4 beta 5c", which must have been the "Toga CMLX" one.

It certainly seemed to handle castling correctly, as it even beat me in one game:

Although it didn't castle itself, it must have been able to understand the castling moves, otherwise it would have had no idea after the castling where the pieces were.

CMLX had a FEN bug that made it crash if the kings were on different files and one still had castling rights (it'll work from any starting position). And it doesn't work under Arena (the code is there, but I accidentally made it accept (and output) 0-0 instead of O-O).

[Alexander Schmidt]

But SMK's UCI protocol says:

"This is why castling moves are sent in the form king "takes" his own rook."

To work properly under all UCI interfaces (including Polyglot) Toga CMLX should do it like in the UCI standart.

[Teemu Pudas]

Note I said Arena. I do that, but only if I get a Shredder-FEN. Arena uses X-FEN and O-O castling.

[diep]

congratulations to Sjeng for its impressive victory.

Rybka 3.0 and Toga played at 8 core machines (real 8 cores, not 8 fake cores from i7) so similar hardware like in world champs 2009.

Sjeng clearly beated them all.
Congrats on Ikarus for its clear 2nd spot.

p.s. don't jammer about bug XYZ in the first place toga's and rybka's shouldn't have joined a final as that can seriously influence the outcome, in this game that all wasn't needed as Sjeng hammered them all.
