Oral is a good example of the anti-Sicilian e4 player. He usually plays the Bb5 lines (and often generates attacks out of them) and against the ...e6 lines, he plays b3, also often generating attacks, as in this game.

Sicilian players sometimes complain about this "avoidance" of their favourite lines, whether the Dragon, Taimanov or something else. It is really just the same problem you face with other openings (although the Sicilian player in particular might admittedly have wasted his youth learning masses of theory that he can never use).
