Playing without a queen

Sometimes, players rely too much on the most powerful piece on the board.  If I get a sniff that someone plays that way, I'll do everything I can to take the piece.  It's surprising how quickly they'll fold when the piece is taken.  I'm not referring to an overlooked capture where the queen is taken; we all do that and get justifiably pissed off at ourselves.  I'm talking about queen sacrifices for position, trades of queens, or queens sacrificed for two other major pieces. 

I think one has to learn to play without a queen in order to develop as a player.
