Monty Moose is quite correct, the Colle-Zukertort, Colle System, etc is an opening for white that has an opening series of moves that is almost identical every time. I have played over 7000 games oat RHP with the white pieces, and I can honestly say that I believe at least 6500 of them have been the Colle. If you play tournament chess, one fantastic advantage of this opening is you can snap off a lot of moves quickly, conserving your clock for middle and endgame play.
