Irontiger: I guess you were right that the move sequence of the variant of Yereslov is suboptimal for black. If I am correct, then will black also win after Kh2.
Incorrect. I had the engine run for at least two hours in deep position analysis.
It's a draw. Plain and simple.

Ok, then forget my previous comment, I replace it by this one :
Yes, it is winning. I consulted the oracle in Delphi.
Now how do we make progress, huh ? Give your engine's lines instead of that.
Qa3 is not a big problem. I had shown in the other lines that black would play Rd2, threatening Rd1#.
Play could have continued 23. Qa3 Rd2 24. Qb3 Rc8 25. Nd5 Rc4: threatening mate on c1 and d1.
The kingside cannot be penetrated.
Well, good luck finding a win.
The pawns are useless, by the way. Moving the g or f pawn is bad, mmmkay?

White has better then moving the knight, it was just an example.
Black has better too:
20. Kh2 Nh1: 21. Rh1: Be5+ 22. Kg1 Rd2 23. Qa4 Bg3 24. Bf6 (to prevent Nb2 attacking the queen and making Rd1 possible) 24. .. Nc5 and white has two options:
25. Qa3 Rd1# or 25. Kf1 Na4:
All those moves after 21. Rh1:+ leave white without any other option except 23. Qa4, which can be replaced by 23. g3. That is a better move for white, although white has to be careful again. Last variation:
23. g3 Rd8: 24. Rh2? Rd1+ 25. Kg2 Ne1+ 26. Kf2 Rd2+ 27. Ke1: Rh2:.
Overall conclusion: it seems a very good sacrifice made by batgirl and the gives white a lot of problems. It is difficult to see good moves for white. White is the one who has to play very carefully in order to stay alife.

Ouch. Typical ckueless computer moves.
27...Kg7 and 28...Bc3 is not the way to go after the pawn. It gives d6 and the bishop has no longer a stable place.
Again, 27...Ra2, and if 28.Rf1 Ra1 White has not won anything.

Of course it's not a win. It's a draw.
Anyways, it doesn't matter what you do. The result is the same.

There is a difference between "play anything until it becomes an obvious draw" and "try to win although objetively it is a draw".
The problem is that the computer choses the first way and then deduces it is a draw. But if you feed him my moves, which correspond to the second option, maybe (I have no idea) he will realize it is a win. The horizon effect is still painfully present is many endgames, and this one is an obvious example.

Nothing has changed.
20.Kh2 and black has very tangible/decent compensation for the queen.
19..Bxa1 wins for black imo, too much material
I was refering to OTB tournaments.
I don't care whether is an otb or online. I was referring to the second part of your statement.

What about it? Not everyone is obsessed with chess. Some of us like to go outside and smell the fresh air (depending on location).
Try it out sometimes.

In the end of your "main subline", 23.Qa3 is unpleasant. After all, the knight is not very stable on d3.
