how does black win this endgame?

Looks like a draw to me. How does Black penetrate White's position? The white Knight is well posted and the fractured Queen-side pawns are not easily attacked.

Anyway, I plugged the position into DR4 and it rates the postion as 0.46 in favour of Black at depth 30.

I prefer Black here, slightly better because of the power of his Dark-square Bishop and much better pawn structure.

This looks like a draw, but black has a very small advantage. I bishop is better than a knight when pawns are on 2 sides of the board. However it looks like white can hold this position or possibly even win with accurate play.

Heh, lets say white does Ke1-f1-e1-f1 for 20 moves just to illustrate ... white has all the chances (however small they might be), black has nothing to play for here.

I don't think Black has any advantage : his bishop is bad and white can cover his Q-side weakness with his Knight.

What are you talking about?

Not pretending these are the best move or anything -- but let me know where black can improve here.  The knight can go to e4 and stuff -- I mean, all white has to do here is not fall asleep.

Like I said, that was just to illustrate -- obviously if you give black 20 moves in a row here he'll win lol

It took white blundering his knight for me to win this position, I just wanted to see if there was a concrete plan that I could follow.  I did bring my king over to the queenside and start messing with stuff but krafty said moving my king over to the queen side lost my advantage,  I was just wondering what plan  I should have. Attacking the quenenside with the king only worked because white hung his knight.

This endgame is easily drawn by white. Yes, there are pawns on both sides of the board, but the c4 post for white's knight fully compensates for this. Once white puts his king on c2, black cannot win on the queenside. White's pawns are actually not a cause for white "being worse". In fact, if white's pawns were on b2 and a2, then black would be the one struggling to draw. If black moves his king to the kingside (the only other winning possibility), then white simply mimics black's king movements. What keeps black from getting winning chances are the black bishop's lack of targets, and black's pawns on c5 and d4 completely blocking its activity. I am not sure what happened earlier in the game, but black made a serious strategical error in allowing white's knight the eternal perch on c4. (this may have been a tactical necessity, so this may not be criticizable).
