Answers.Body: <p>I used the Colle-Zukertort for a while.  The 150 attack is fairly well known to Pirc players, and the Barry Attack is not good enough to hold you through if it doesn't work.  You can get by at the club level with this repertoire, but you're limiting yourself because, aside from the few examples given in books about those openings, few if any players over 2000 ever lose to them, because they can think them through.  If you're OK with just throwing away your advantage with the White pieces to players over 2000, go for it, but personally I would advise you to go with something more sophisticated.</p>
