Who doesn't love a good knight sacrifice?

For the longest time, I stayed away from queen pawn openings. Bobby Fischer, after all, had proclaimed 'e4 best by test.' But we now see it played in championship matches by World Champions, so perhaps Mr, Fischer abandoned it all too quickly. I theorize that queen pawn openings use a slightly different part of our brain, and are better played by some players than others depending upon development of said part. Or, it's all hogwash. What do you think?
