TCEC Season 6 - Stage 1c now live

[Robert Flesher]

Congratulations to Naum, Stockfish, Fire, Shredder and Spike for qualifying for Stage 2 after Stage 1b ended late last night.
Equinox is still the best 6th placed engine so unless the 6th best engine in 1c can score at least 7 points, it will qualify for Stage 2 as well.

In this game Equinox is showing a loss. Although the connected passers look strong why is this game shown as a loss?

Indeed, both engines thought it was a draw. The reason Equinox was awarded the loss is "White's connection stalls" according to the TCEC website, which makes me think that Equinox crashed. I'll wait for more informed people to inform you.

[Martin Thoresen]

Equinox crashed twice when running on 16 cores so it was later reduced to 8.
I suggest reading the TCEC news.

two questions:
why plays junior 13.3 e not 13.8?
why don't play deep Fritz 14?
thx

[Martin Thoresen]

why plays junior 13.3 e not 13.8?

Junior Yokohama has a SMP bug that Amir could not fix in time. It crashed a lot during the testing.

why don't play deep Fritz 14?

It doesn't exist as UCI or xboard engine.

Hi Martin,

Also 2 questions:
* Is there somewhere listed the EGTB/EGBB used by the engines (for instance, is Scorpio playing with bitbases and if not, why?)
* As a kibitzer of the chat (not participant), how do you prevent it from scrolling? (I could do it in the previous TCEC...)
TIA and bravo!

[Martin Thoresen]

* Is there somewhere listed the EGTB/EGBB used by the engines (for instance, is Scorpio playing with bitbases and if not, why?)

Click the rotating gear next to the engine logo for info on that. I suggest reading the Rules & information in the Help menu.

* As a kibitzer of the chat (not participant), how do you prevent it from scrolling? (I could do it in the previous TCEC...)

I don't think you can do that without logging in. You can contact Chatwing support for more info on this, info@chatwing.com

Best,
Martin

Thanks Martin!
So it says Scorpio IS playing with bitbases.
But it doesn't show in the "Tablebase hits" window (GUI problen?) and I remember Dan Shawul asking in the Chat: why is Scorpio playing without bitbases?
Was he wrong?

First of all, Scorpio is a winboard/xboard engine and they never show TB hits of any kind. The "TB Hits" is greyed out because of this.

Second of all, clicking the text around the TCEC Web GUI will bring up small tooltips that gives you information. This is also explained if you read the Rules & Information section in Help, as mentioned before.

Hannibal is qualified as best 6th !
