Queen's Gambit Declined--Slav Defense, Exchange Variation

The Queen's Gambit is a good opening if White is seeking to give Black a challenging game. It is usually declined by Black and a popular way to decline it is with the Slav Defense. My coach recommends responding with the Exchange Variation.

We will start with a simple way for White to trap black. 

If 15... RxQ white gets a family fork when he captures Black's Rook with his Knight.
