Stockfish 1.4, the final weapon

[slobo]

72.702<--1:option name UCI_Chess960 type check default false

Are you sure to set to true this UCI setting before to start the game ?

No, I did not set this Toga UCI parameter to true. I see it now.
This parameter does not exist in Stockfish.

In Toga-CMLX-1.4.5e-1cpu I set this parameter "checked" - ou "true" as you say - but in two FRC games it is Stockfish that is crashing.

I would be great to use all the good thinks that are in TogaII in Stockfish.
Or may be it's already the case ??

and what about to improve TogaII with tricks that are Stockfish ??

Btw they're both great free engines !
Thanks to the community !

...
My main goal is to see Stockfish 1.4 to become the strongest open source engine to date in all hardware categories (32/64 bit, single core/SMP, the toughest will be single core 32bit where the Toga's can say something) and with a bit of luck perhaps the strongest free engine too (at least in SMP), with the notable exception of Rybka 2.3.2 that is still on another level...but we are slowly getting there.

What a game; what a strategy by Stockfish! Unfortunately, not enough to win.

Hi Tord, Marco and Joona,

I guess from this thread that you have already fixed the castling bug by now, nevertheless I've just started using the engine, and thought I'd bring these 2 errors from the same starting position to your attention. Maybe could be helpful for testing purposes. I don't know.

I can confirm UCI_Chess960 was set to true. GUI was WinBoard via Polyglot.

Thanks for an otherwise splendid program. Best Regards

I guess from this thread that you have already fixed the castling bug by now, nevertheless I've just started using the engine, and thought I'd bring these 2 errors from the same starting position to your attention. Maybe could be helpful for testing purposes. I don't know.

Hello Russell,

Yes, the Chess960 bug has been fixed since some time. Chess960 now appears to work flawlessly, apart from the fact that the lack of development evaluation in the current version of Stockfish hurts its Chess960 playing strength a little.

Thanks for an otherwise splendid program.

And thanks to you for your support. We hope you will be even happier with the next version.

[Eelco de Groot]

Hello Tord,

Do you maybe know if the Chess960 bugfix could also be used for the Stockfish 1.3 code? Or was it a specific problem with Stockfish 1.4.? I have not yet tested if everything works in Chess960 with the older version, I was hoping that you guys would find a solution to the problem

Regards, Eelco

Hi Tord, Marco and Joona,

I guess from this thread that you have already fixed the castling bug by now, nevertheless I've just started using the engine, and thought I'd bring these 2 errors from the same starting position to your attention. Maybe could be helpful for testing purposes. I don't know.

I can confirm UCI_Chess960 was set to true. GUI was WinBoard via Polyglot.

position fen rnkbbrnq/pppppppp/8/8/8/8/PPPPPPPP/RNKBBRNQ w FAfa - 0 1

I tested this position with Ancalagon based on Stockfish 1.3 and Shredder GUI accepted it as a Chess960 engine, no crashes, I see no castling moves yet in the PVs so it could be possible that there is some kind of problem there, but I don't see anything like the above.

As the Glaurung site is well known, would it be possible to distribute Stockfish from this site too?

kind regards

[ernest]

Yes, the Chess960 bug has been fixed since some time.

Hi Tord,
Is it fixed in the JA versions stockfish_14_ja.exe and stockfish_14_x64_ja.exe of July 5th ?
