march the king, and the rook confines the black king to the kingside, lock in the kingside, trade one of your queenside pawns for the bishop and queen the other and you win!
Typical endgame position

I understand the planning aspect, and thats basically what I did until my opponent blundered. My question is if the position itself is a win for white or a draw if black plays correctly.

I think White should win, but it will be hard work, and the Rooks must stay on the board, as NM tonydal said.

That's really good to know, Tonydal and Rooperi. I did the exact wrong thing in this position. I traded rooks with the plan of advancing my queenside pawns. Black played incorrectly (though he wasn't alone in this) and I got the win.
Are there some good rules or maxims about when one should and should not trade some of the heavier pieces in endgames?
rednblack - opposite coloured bishops have a strong drawing tendency, because they cannot attack the other coloured square, meaning often blockades can be set up. So to increase winning chances, we need other pieces that can attack other squares. Take a look at your position without rooks and with Black to move:
I'm curious as to whether someone can tell me if the position found below is a draw or win for white with correct play. I typically come to endgame positions similar to this when playing the English opening, so any insight would be welcomed and helpful.
