I really enjoy opposite-side castling positions where I'm able to launch pawn storms and put my opponent under pressure. For this reason, I actually enjoy the Exchange French as Black / I want to take up the Scandinavian Defense, since in both of those openings Black commonly castles queenside while White castles kingside. In what other openings does this usually happen?
(This question was edited; before I was asking about openings that lead to opposite-side castling in general, but in e.g. the Sicilian Dragon when Black castles kingside, White can keep it boring and castle kingside as well. By contrast, this doesn't happen as often when you castle queenside.)
