Korchnoi Encounters the Center Counter

Viktor Korchnoi is one of my favorite players, as a player and a person.  I have interviewed him and played him in a simul (I had to convince him that playing 50 players in a simul wasn't so bad in the United States - he won them all).  Here is a nice game where he sacs his rook to get his queen into play against the enemy king.  One slip by his opponent and he checkmated him.
