Breaking the Pin

So i'm reading a magazine, and i found this game. It's a very nice one, showing how to punish your opponent if he carelessly sets up an annoying pin. White breaks it in nice fashion, giving up his queen, to force a king hint all the way down to his own side of the board.

EDIT: i'm actually concerned about PRIVACY, guys. sigh...the magazine was CHESS LIFE FOR KIDS.
