Queen's Gambit Declined--Exchange Variation

I was looking for an easy but sharp opening for White, one that does not require the study of enless variations. I was advised to use the Queen's Gambit. The Queen's Gambit is frequently declined and this is the variation that I was advised to use. 

Main Line

A common trap White should avoid:

If Black Plays 6... Bf5

If Black Plays 5... c6

Notes: In the main line, White castles Kingside and proceeds to attack on the Queenside. In 5... c6 position Black has bad pawn structure after White  plays kd2 and exchanges Bishops.

If you have ideas, comments, more variations or traps, please do send them in.
