I'm a newbie at chess. I'm not into openings or advanced playing systems
london system or colle system 🤔
Used to use the London but gave up on it, black can play the boring line after ...e6 then ... Bd6 swap off the black Bishops and tough at our level to push for advantage!? The Zugertort/Cole variation is interesting where white plays a coles setup with black Bishop on b2 had few nice wins with this line but only due to my opponents help?!! Lucky me😉

Depends on the Colle, Koltanowski? or the Zukertort?
I'd probably go with the London ... You can play it more as a system than Koltanowski... The Lodon is about the same with the Zukertort. No short cuts with these "systems" to play them effectively.. at any rating you are required to burn the midnight oil in study prep.
which one do you choose?
