Disappointing Draw

I had black and managed to get a winning position, but unable to finish; I didn't have a mating idea. Please help me. In this position, I'd just captured white's pawn and it's white to move.

Does anyone know how to win this position for Black?

For future reference, it's easier for others to give feedback when you add the game and/or FEN of the position. Here is the full game.

I'm just commenting to say I don't have an answer. Even with the help of Stockfish it's quite a challenge. I have the same question, how do you win this for black?

The position after 65. Kh2 is even more bizarre. It's supposed to be winning but I can't find a way to break through if white keeps hiding in the corner.

Thank you. I'm still learning the interface for the forums. I just "discovered" that I can't do it in iOS.

I did have a look with Stockfish. It didn't seem to fare much better.

The missed blunder at 74 is where I had my opportunity that never reappeared.

So you didn't find that particular winning move a move 74. It's okay, it happens to all of us. But the move you played instead is just incredibly bad, throwing away the g-pawn for nothing. I seriously can't imagine what you were thinking.

After throwing away that pawn, the position is just a draw.

What's odd is that I was waiting for my opponent to do something like what he did. I just didn't see it at the time- tunnel vision I guess.

My goal with the g pawn was to break the tension, draw him further down the board out into the open.
