En passant is a bit funny in that, once you learn it, it's tempting to use it when it would actually be better not to. When I played tournaments in high school, most players knew about it, but most players were still quite amateur, so one could offer up a position in which the opponent could perform an en passant, but the en passant was actually fairly detrimental, and more often than not the opponent will take it, because "hey cool I can do that weird pawn move".
