I had this interesting position against me today. White could have won in 55 moves with Kf4! but foolishly just took the pawn instead which draws.

Can you mate the black king with two knights
The position is already draw no matter what you play....

According Tablebase this is a win in 55 moves because the black pawn avoid the tricks based on pat.
So as you said Kf4 is correct but I'm not sure a human can play this perfectly

No, you're wrong, White can win if the pawn remains on the board, as it prevents White from stalemating the Black King.

This is well known. Well, among chessplayers.

This is an old theme. If your technique is good, you'll win.

Can I ask you why you took the pawn?

I was black and I had just played f5+ hoping white would just take it which he foolishly did.

Here white can win in 155 moves with Ne2! which is the longest win possible with these pieces.

My mistake, I didn't read your post carefully. I re-read it, it's clear you were Black.

My this is a long one. I doubt I could be so exact
