Knight vs Pawn, by request.
"My nephew and I were looking over this position and wondering if it was a draw. It seems like it to me. If it is, I wonder if with a little variation it would be winable by white?"
White to move. wizzifnab, 2007.
It's a draw. Black's knight blockades the a-pawn, while Black's king protects his f-pawns and prevents infilitration by the enemy king.
White's king can't penetrate along the h-file because 1.Kg3 Kh6 2.Kh4 Kg6 and Black's king can shuttle back and forth between g6 and h6, but White only has the one h4-square. White king also can't cross over to the queenside for a couple reasons: (a) The knight will then find a way to fork the king and a-pawn (b) Black's king will have time to reach h4 and thus win White's f-pawn if the White king wanders too far away.
1. a5 Nc5 2. Kg3 Kh6 3. Kh4 Kg6 4. Kg3 Kh5 5. Kh3 Kg6 =
Remove either of Black's pawns and it's still drawn, but remove both and it's a win.
