Double exchange sacrifice!

It's rare to pull off a double exchange sacrifice (rook for a minor piece) in a game. I did it in a correspondence game where I had no clue how to continue. My opponent declined my draw offer so we played it out. And I'm glad we did. 

After each exchange sacrifice, stop to consider White's compensation. Sacrifices only make sense when there is compensation. In this game White's compensation is the connected passed pawns which ultimately triumph.
