Game: https://www.chess.com/../daily/game/458344627
Move: 12. Bxb4
Reasoning: Before my sacrifice I played Rc8 to set up an idea and provoke/bait my opponent into playing b4. I noticed that I was behind in developement and it was tough to get my pieces into the game without losing any pawns. So I played 12. Bxb4 
to forced cxb4 (which didn't happen in the game and was a big mistake by my opponent). The idea is to play Nxb4 which attacks the queen and after the queen moves I play the unstoppable Nc2+ which is only possible because I played Rc8 before my sacrifice. To sum it up I get a rook and two pawns for my bishop and knight + my opponent can't castle. I figured this would be the most comfortable way for me to play so I don't get pressured too much in the opening.
