N vs. B ending, pawns on both sides I had this position today, with White to play:

    [FEN "8/1p3kpp/p1n1p3/3p4/3P4/1P2B3/P2K1PPP/8 w - - 0 25"]


What should White's plan be to try and win, and are there any particular pawn structures White should aim for? Does White actually have any advantage?

In the game I got to the following position:

[FEN "8/2B5/2n1pk2/p2p2p1/Pp1P2P1/1P2KP2/8/8 w - - 1 35"]


and there seems to be nothing (the computer doesn't find any way to make progress either). 

I was hoping to use the fact that I have a tempo available (Bc7-b6) to force my king through the kingside after something like f4 gxf4; Kxf4 Kg6; g5 , and move my king around Kh5-h6, however Black always has ...e5! to break out once my bishop is on b6 and my king is not covering e5 or d3.  The actual game followed my idea but it ended up in a wrong-colour rook pawn situation.
While this position is probably a dead draw, there is no way white could claim even the slightest advantage here. 

Sure, there are pawns on both sides of the board, but the d4-pawn closes the juiciest diagonals for the bishop and is an eternal target for the black knight. 

Even more important is the fact, that after black plays b5 the queenside is completely sealed. The white king cannot intrude and the bishop cannot attack anything. The same isn't true for the black knight … if white walks his king to the kingside he has to take possible counter play on the queenside into account.

Just playing g6 and putting the king on f7 should be enough to defend the kingside for black. But if ever black really starts to march on the kingside with king and pawns, this frees up the black knight not only for queenside counterplay but also for kingside defence. I don't see how that would ever result in a white breakthrough.

So to sum up: This just isn't a position where white can put any pressure on black. Of course in the game apparently black put a lot of pawns on black squares, turning them into targets for the white bishop, but even that wasn't enough to tip the scales.
