So yeah.. if you want to allow cursed wins (which I agree), engine programmers should be alerted before submitting the binaries.
Here is the problem. You can not claim the 50 move rule unless you have played the 50 moves. This never happened in the game.
TCEC rules state: Cutechess will also adjudicate 5-men or less tablebase endgame positions automatically.
The game was adjudicated a win. And you could force a mate but beyond 50 moves.
This is what happens when you have rules to adjudicate games, and not let the programs play out the moves.
As a tester I never adjudicate games for this reason.
But TCEC is not testing engines. They are running a entertainment tournament. So they have rules to shorten games, dubious openings to force more decisive games etc.etc. This is done to draw people to the site to watch the games.
This is just the nature of the beast. I would not get to bent out of shape about this. All the programs are playing under the same TCEC adjudication rules.

Is Cutechess using Syzygy? Then it should know it's a draw. If it's using Nalimov tablebases it should be adjudicated manually. The programs know it's a draw and one of them may have counted on that.

cutechess adjudicates using Gaviota. And yes, both engines had the game scored as 0.00 when it was adjudicated.

Indeed. Is the TD aware of the situation?
Martin is aware but not sure Anton is. Martin just said the result would stand because rules are rules.
I don't think they intended for this to happen though.
If true and they stick by their "rules are rules" and "our head is in the sand" mantra, they can kiss their little tournament , as it stands today , "good bye". Idiocy at its finest - if true. Hopefully it's not true and the results are "fixed", make that "corrected". 😊
This is a bit of an overreaction.
Haha - was waiting to see who would pick up on that - just kidding - I really don't care one way or the other.
Engines showing 0.00 due to 50-move rule, but position was auto-adjudicated as an M72 TB win

Not much discussion possible.
Both engines know that it's a draw (0.00) and play accordingly.
Suddenly the GUI decides otherwise and is clearly not following the rules of chess as implemented in the engines.
It's kinda ridiculous, but not very important.

Agreed, it should be a draw. As I posted in the TCEC chat, the adjudication should match the result if the engines had played the position out. In this game, it was a 50 move draw.

I used to argue very bitterly against this, but EVERYONE ALWAYS said back to me, that if the tb says it is a draw or a win, then that is what TCEC will listen to.
And regarding the 50 move rule, it does not apply in a position where it is proven that it can be a win after a larger amount of moves, and if TB says it is, then it is.
I didn't use to agree but i was told every time i complained, that this is how it is. This is the TCEC rule.
So why does everyone just wake up now? It has happened many times and everyone agreed to it.
No one was moved by the fact that the engines played accordingly to a different reality, as they were wrong.
And Cato too, said that "if we don't listen to the TB's then why would we need them? Now we have them, we should only say thank you! Don't start saying they are wrong!"

Check section 9.3 of the FIDE rules. There are no exceptions in the current rules.
What needs to be clear is what tablebases will be used to adjudicate a position. Clearly the newer DTZ50 tables are superior to DTM tables.
