Here is a really exciting game where Fischer went over the game later and annotated it according to chessgames.com. Fisher uses a strange line of the Hungarian to defeat Tal. I believe the annotations are Fischers because they are direct and as a matter of factly, his style.
What's really interesting is that Fischer starts talking about the endgame on MOVE 6! He states that the ensuing endgame (after move 6) is not good. The opening determines the endgame. Know your openings but know your endings better!
