Then I lose, the games were meant to illustrate the principle rather than be perfect. I could have done a bit more checking when I was writing the post, but it took quite a long time to write, and I was doing the annotation inside the post rather than using the database tool. In my defence the game was from ages ago and I just couldn't remember what I' ...[text shortened]... you're right, 46. ... a5 was result changing. I need a minor miracle to even draw without that.
Instead of rushing your king up you should have traded your f pawn for his e pawn asap and then rushed your king over to win the kingside pawns. In endgames there is no need to rush. If you can, go win all of your opponents pawns and then queen yours. You made it unnecessarily complicated by removing your king from the action. Another way of thinking about it is that you had a pawn and bishop tying down his king. Thats a good thing because your king is a better attacker than his knight is a defender...and then when you rushed your king up you needed your king bishop and pawn just to tie his king down. Aslo by saccing that f pawn when you could have just traded it is another act of hastiness.
The act of this plan may be hard in practice because of his outside passed a pawn but wothout calculating anything my intuition says you can somehow swing your bishop over in time to stop his pawns. Maybe not though. Its difficult but still, being hasty threw away any winning opportunity except by the opponent playing bad moves.
