Lol. You can check out my log if you want. That is what I play. It probably shouldn't be called "Colle" but that makes me sad so I'm glad you're calling it the Colle,
.
It should probably also not be called "Zukertort," either.
But besides all that, I think it is a perfectly fine opening if black plays e6 early. If black does not, white really should know other setups. I don't really (yet) but I know I should, lol.
I used to be much more of an expert on c3 Colle (the *actual* system Colle and then Koltanowski played).
