positions that stockfish does not understand who is better

[dangi12012]

Also it might not be a win for black after all like you suggested!
Except if arena clears the cache when going back in the game (which i dont think it does)

When rerunning the game 2nd time - it was drawn. (because of cached positions probably)

Rerunning the 3rd time gave white a win:

But if we let Stockfich play it out playing both sides, let say game in 5'+5" Minutes, will Black still win ?

With Stockfish playing both sides there is no guarantee, as it obviously misevaluates these kind of positions and therefore is prone to do very stupid moves also as black. You have to let an engine that knows two Knights are worth more than a Queen here play black. Such as Queeny. Then it will virtually always win with black, no matter who the opponent is.

It is not that simple though, since tactics is also very important. I played 10 games with Queeny as black against Texel as white using some different time controls to get some variation, and Queeny was not able to win a single game. The result was 9 draws and 1 loss for Queeny. Some games were pretty close to a black win though.

I also played 10 games with Queeny as black against Stockfish 15 as white, and as expected this was easier for Queeny. The result was 6 wins for Queeny, 3 losses and 1 draw.

Well Queeny is a retuned engine that would be around 2300 Elo in orthodox Chess. So at fast TC it will start to make tactical errors, and against opponents that outsearch it 10-20 ply that is usually fatal.

The longest time controls I used in those games were 10min + 2sec/move and 6min + 6sec/move. What time control do you think Queeny needs to "virtually always win with black, no matter who the opponent is", assuming it runs on a computer where it gets around 2.5-3 million NPS?

Oh, I looked at a game you posted, and saw 120+4. That seemed a bit short, especially since I am not sure it would properly use the increment.

But I would have expected 10 min to be long enough. Apparently the tides have turned; I was speaking from the experience I had with this some 3-4 years ago (I think). Then Queeny had no problem at all beating Stockfish. Apparently Stockfish has gotten a lot stronger since then.

I seem to recall that you had programmed Texel to understand giving 2 Knights for a Queen was a bad deal in this situation. If so, it should have no trouble at all beating Stockfish with black, and there would not be this 1000-Elo gap in tactical ability.

Yes, Texel does know about this imbalance, but it is still not trivial for Texel to beat current Stockfish as black in this position. One complication that sometimes happens is that white manages to draw by a kamikaze stalemate defense, like in this game:

I think Texel will win most games as black though with 5min+5sec/move and 4 threads.

Some observations I have made:

* Special evaluation knowledge (2N > Q) for this imbalance can be worth more than 1000 Elo points for an engine in the 2300 range.

* Even with the evaluation knowledge, search is very important because the positions can get very tactical.

* When Queeny plays black vs Texel from this particular position, it lets Texel trade a queen for two knights. This does not happen when Texel plays black. Maybe it is caused by some combination of search depth and other positional factors for this position.

* Other positions having the 7N vs 3Q imbalance may be harder or easier to play without falling for deep tactics.

* It is actually 9 years since the last time I investigated this imbalance. I didn't think it was that long ago:

Another evaluation feature that might be useful, but which Queeny does not have, could directly award having all Knights twice protected. And a bit of King Safety could also help. I still have the feeling that a good evaluation should be able to stay in a position that is invulnerable to tactics. But with material only the only incentive to maintain positional health is seeing the tactical punishment of positionally unsound moves. And that is very risky when you are badly outsearched.
