Hello! I have played this game recently. Stockfish gives advantage to the black, I have followed it for some time, but cannot understand the main idea. It doesn't seem possible to promote any of the pawns on g or f. So, why there is an advantage for black?
lichess.org/JpDLhAXM/black#98Ill take black any day in this position
1) Blacks bishop is waaaaay better than a rook here, it has the whole diagonal for him, its the perfect bishop.
2) Ironically white's h pawn is not a threath for black, it protects the black king from any attack/sacrifices
3) Black advanced pawn on the A file is a constant checkmate threat for the white king which limits the white queen movement, the b2 square needs to be guarded constantly
4) White cant break through with any pawns ! his c pawn will never be pushed.
5) but most importantly black has 2 connected passed pawns on the g/f files
= Only black can make progress in this position and if he plays precise and careful moves push his pawns and promote i really dont know if its winning tho but you cant lose with black for sure.
black 6 pawns withe 5 pawns 5-6 = -1 but in this position its not mean advantage only 1 pawn more for black.
I think it is a draw. Neither side can make any progress.

Well, I think the same, so it was strange for me to see Stockfish giving a solid advantage to the black.
It suggests to promote pawns, as far as I can judge, but for white Stockfish responses in a peculiar way. I played against it for some time and didn't manage to promote, lost finally.
Stockfish analysis may not be accurate for such endgames, I think. Basically the "solid advantage" Stockfish gives is with regards to the material advantage. Stockfish can't seem to grasp the "advanced drawing ideas" which comprises of an idea with many possible candidate moves by both sides.
It is easy to see. Take any tablebase draw of say KR vs. KB. The tablebase will indicate draw, Stockfish will indicate an advantage of about +2, until after 50 useless moves it realises that there is nothing more than a draw.
