It does not switch to Kg4, but clearly the same problem was already present.

I am now strongly suspecting the problem to be the short 16-bit keys stored in hash entries.
Like how the top engine of 2005 was crushed in tournament condition.

But someone mentioned in comment section of that game, that the collision
bug on that specific position was reproduced using Shredder 9.0 32bit.

Sorry I don't have that version : )

I think you are right, but incorrectly doing what you say was the reason for search instability in the past (Eelco once improved it significantly). Since the search is again (or still) unstable, it might be good to very carefully look at it again.
I think any search with a hashtable and path dependent evaluation (repetitions and 50 move-rule) will be inherently unstable.
Not to mention LMR which is the greatest source of instability. Normally with alpha/beta if you change the move ordering, you only change the search time, not the result. Not so with LMR/LMP/etc...

A hash collision is pretty unlikely the cause. One can intentionally cause one wrong hash every 1M nodes and not see any effect on the scores whatsoever...

Stockfish has one wrong hash about every 22,000 nodes (16-bit keys in TT entries, 3 entries per bucket), but that does not seem to be the cause of the problems here. I've modified SF to use 32-bit keys in TT entries and can still reproduce the problem.

Yes, it looks like an extremely unlucky hash collision very close to the root of the search tree. Funny game...

The good thing is that a problem was discovered. If it can be reproduced, then it can be fixed. I can reproduce the 0 score, so maybe the problem can be solved and SF will get even stronger from it.
