Here's a fairly straight forward line in the Colle-Zuckertort. The interesting thing in this line are black's attempts to capture the light squared bishop. These are all tacticts I've been victimized by in the past. b6 followed by Ba6, Nb4 when the bishop can't retreat to e2, and the odd Nh5 with the very concrete idea of Nf4 forking the bishop and the queen. In the position below white has avoided those attempts and is ready to play Ne5, c4, Rac1 with some advantage.
