Can black draw (or win?) this Gruenfeld endgame?

WannaPlayLot

I won a piece, but lost the game. Any plans for drawing or winning this game?

Technically Black is better after 19...ba6 (pawn up), or maybe even better 19...Nh4+ first, to damage white's pawns. Converting isn't easy, of course.

Anyway, after keeping the piece white is somewhat better, but the rest of the game is blunderful, both sides involved.

20. ... Nxa2! 21. Kxa2 bxa6

or

20. ... Nxa2! 21. axb7 Rb8 22. a4 Kf8! and white king can't move Kf3, so your king should arrive c7 first. I would certainly try this or immediately 20. ... bxa6 21. Kxf3 which leaves black a pawn up.

EDIT: 20. ... Nxa2! 21. axb7 Rb8 22. Rb1 Kf8!

What about 26...Na5!?

But 27. Rb5 complicates?

I guess you mean 20...Nxh2, right?

It looks like a blunder after 21.ab7 Rb8?? 22.Kxh2 and Black can resign (he can't take on b7 because he gets mated)

May I suggest 26...Nd2+ as an improvement?

23...e5! and the hell did you think not to play Nd2+ as suggested?! Probably you didn't see this plus because a5, Nxb1, a6 - white is winning.

Still incredible game!
