The way I see it this would only be true if:
a) there's a problem with the corresponding 5-men TBs or
b) there's a problem with the engines probing them or
c) there's a problem with what the engines do with the data they get from the TBs

Nevertheless you may have a point there, even if it's not for the reasons you believe.

Two more games. Everything as before except for
- 6-men Syzygy
- move limit extended from 120 to 150 plies
- TC extended to 5h+30s to provide for the same 5min/move average as before

Both games ended without a decisive result despite the extended move limit. Draw? I did a playoff for the final position of the first one - same settings except TC=4h+30m and no move limit

Perhaps Lyudmil could play through all of the 210 moves and tell us where the engines or TBs went wrong?
just briefly(but thanks again for the tests):

-playing g6-g5 for black is a major mistake, after which the ending is probably already not winnable; with white pawn on g4 and white knight on d4, the f5 square is controlled twice by pieces of lower power, so f7 black pawn remains pemanently backward and black is devoid of attacking chances on the king side; in order for black to win this, it should play f7-f5 instead, like in your previous 2 games
- this is basically a roll of dice; with couple of games, everything can happen, no matter the TC, you might have draw at 5 min., then black win at 1 hour, draw at 5 hrs., and black win at 3 days for the game again; similarly, a one-threaded engine can frequently pick better moves than even 32-threaded one, less frequently, but still frequently enough

my short TC tests give 70% + black wins, but this is not very much reliable too.

the black structure is simply winning in terms of eval: that is what I believe.

- backward b2 white pawn
- pawn majority for black on the queen side

those are 2 very important features that should swing the balance in favour of black.

the general rule should be that the weaker side is able to hold, only if it it does not have any additional weaknesses apart from the material deficit, and here white has 2.

same position with no backward pawn and no pawn majorities is equal, for example.

but those are just my crazy old definitions, of course no one believes in them.

also, too many pawns still left cumulatively, 12 in all, with smaller number of pawns drawing chances increase.

I suggest, for the next run, whoever does it, buying a 64-core, and letting the engines calculate for a month or so.
I took a peek at all those 3 games which was played with long time
control. The 76-mover game, 210-mover, and another 76.
Looks like a convincing draw there.

No zugzwang, black could probably win if there was,
but white has a lot of space. Mobility for rook, centralized N and space for King seems to be at max and can do anything they want.
Looks like black cannot break whites fortress.

regards

those are just 2 games, the other is simply a continuation of one of the games.

did you also peek at the 2 other VLTC games, both won by black?

I wonder why this time engines chose Qd1 as first move, while Qc1, keeping f4 square under aim, and b2 pawn as well, is much more natural and strong.

I am 90% certain black wins this.

For the moment this endgame is considered to be engine draw, but we are not 100% certain yet.

how did the real game end? (because I see some exclams attached to black moves)

who was the commentator, he rightly gives Qc1 an exclam(instead of engine-picked Qd1, and f7-f5 too, chosen also by modest me)

yes, black needs play on both wings, in order to win, but that is available.

for the time being, until definitively proven otherwise, I consider this position a black win.

btw., when are you going to test it with 7-men enabled?

Looks like Lyudmil was right (as usual, lol).

look very carefully again here: why would both SF and Komodo pick Qc1 as their first move here(and indeed the better choice), and go on to win, while choose the much more nonsensical Qd1 in the second run??

both SF and Komodo at that.

what difference do 6-men make to choosing Qd1 instead of Qc1?

there is something very fishy here, according to me, but I do not know what it is.

Sorry Lyudmil my copy and paste problem : )
The other game is indeed just a continuation.

Didn't notice until you pointed out that it was just a continuation.

in the second game, starting from this position:

[d]8/8/5kp1/pp1p1p2/2pN1KPP/P1P2P2/1PR5/3q4 b - g3 0 2

Qe1 instead of the played fg4 clearly wins, for example g5 Kf7 Rh2(what else) Kg8, and white is in zugzwang:

[d]6k1/8/6p1/pp1p1pP1/2pN1K1P/P1P2P2/1P5R/4q3 w - - 0 5

engines make so many mistakes, seemingly much more with 6-men than with 5-men.

for the future, I suggest to always disable 6-men.

I've tried searching for moves up to this endgame, even asking on an russian chess forum, one russian member replied: he know Peter Korzubov and he regularly participate in Minsk tournament. Next time he sees Korzubov, he will ask about this particular game.

Lyudmil: you're probably right in the claim that g5 is a decisive mistake.

Remember this was played on a 2-core laptop.

Qe1 instead of the played fg4 clearly wins, for example g5 Kf7 Rh2(what else) Kg8, and white is in zugzwang:

[d]6k1/8/6p1/pp1p1pP1/2pN1K1P/P1P2P2/1P5R/4q3 w - - 0 5

engines make so many mistakes, seemingly much more with 6-men than with 5-men.

for the future, I suggest to always disable 6-men.

With 2 best lines, SF (with 6 pcs Syzygy) switches to Qe1 after 1m42s :

I saw a man who jumped out of a window when his building was on fire and he broke his leg.
Therefore, never jump out of the burning building.

Having 6 man tablebase files will solve more problems more quickly than not having them.

As for an engine making mistakes, yes. Stockfish does make mistakes. But it makes less mistakes than any other engine which is why it wins more games than any other engine.

It also makes less mistakes than any human on the planet, including Carlsen.

If a really strong engine failed to solve a problem, it probably means we did not give it enough time. Even bad pruning decisions will eventually be overcome by sufficient depth, because there is no algorithm that prunes down to zero (unless it is a pure loss or unless the program has a serious bug).
