Based on long analysis I do not see big problems and I wonder if black played worse than a compuer or chess programs simply do not understand the position.

Stockfish does not see big problems for black when it plays 6...Nc6 and maybe the mistake is later
I will analyze the next moves later with at least 18 hours of analysis for every move to see where is the problem.

The pv is the same as the game with different order of moves so I will check the position 2 moves later after
Be6 10.Nc3 0-0 11.Ne5
Parent - - By Bouddha (****) [gb] Date 2015-06-03 14:26
After 9...Be6 it may be still possible to save a painful suffering draw.....
But again, why suffer when other openings provide full compensations !??

The mistake seems to be 17...Nb8 and I wonder if black really suffers after 17....f6

Before 17...Nb8 here is stockfish's analysis(only 0.15 pawns for white)

Stockfish_15060221_x64:

r1b2rk1/ppq2ppp/n2b4/2pPN3/2P1pP2/PP6/4B1PP/R1BQ1RK1 b - - 0 17

After 17...Nb8 18.Qc2
it seems to be big advantage for white

FEN:

Yes, 17...Nb8 is probably the loosing mistake.

17.... f6 was the move to play.

That been said, I still believe white has a clear advantage even if computers says its =

i.e.

1. e4 e5 2. Nf3 Nf6 3.Nxe5 d6 4. Nf3 Nxe4 5. d4 d5 6. Bd3 Nc6 7. O-O Be7 8. c4 Nb4 9. Be2 O-O 10. Nc3
Be6 11. Ne5 c5 12. Nxe4 dxe4 13. d5 Bc8 14. a3 Na6 15. f3 Bd6 16. f4 Qc7 17. b3
f6 18. Ng4 f5 19. Ne5 Nb8 20. Bb2 Nd7 21. Nxd7 Bxd7 22. Qd2 Be8 23. a4 Be7 (
23... a5 !?) 24. Be5 Bd6 25. Bxd6 Qxd6 26. a5 Rf6 27. g3

Thanks Uri, I was a big fan of Movei back when I used to run engine matches.

A disadvantage of -0.43 seems very saveable (I've saved positions where Stockfish was calling a disadvantage of -1.50 and worse) though I think the position after 24. Kh1 was lost for black (I think I did defend optimally after that, because I'd have resigned earlier with other black alternatives, specially considering that I couldn't even defend in my analysis against Stockfish's Depth 32 moves, and Bouddha was playing considerably better than that, obviously.)

I disagree with the assessment that 17...Nb8 led to a lost position in the sense that I believe the position on the board is not a mate in X (i.e. I think that if 28men tablebases were to exist, they'd declare the position after 17...Nb8 as drawn) but I agree that 17...Nb8 was the losing move in the sense in which it led me to complications and to positions where Bouddha could show his clear superiority and defeat me.

From my analysis I'll say that I fully believed that I could draw the game against all the alternatives to 24. Kh1, which is why I went there, but it took me by surprise and I only realized I was losing at that point.

As to your comment that you're not sure if this was Black's fault, or the engines' fault, I will claim that nowadays Stockfish left to analyze a position unattended for 24 hours probably plays much stronger than me (at least against someone that doesn't know that's the entity playing - which is a reason I'm in the process of quitting correspondence chess - the other being that I just can't keep up; I've seen other people managing to come up with great methods to take advantage of current technology, while I'm basically playing the same way as in 2012, which seems considerably outdated), though I'll say Stockfish still makes terrible misevaluations that people can take advantage of, and one never knows if some position is of that kind.
