VHF2L (short for Vandenbergh-Harris F2L) is a step of the Vandenbergh-Harris method that basically does the same thing as ZBLS using much fewer algorithms—the last slot is filled in while orienting the edges of the last layer. The reason why there are much fewer algorithms is because all of the cases have a F2L pair already or just one move away from making one. If the cube doesn't apply to that, you have to create a F2L pair or make it one move away.

Note that all of these algorithms are written in the Western notation, where a lowercase letter means a double-layer turn and rotations are denoted by x, y, and z. (how to add algorithms) Click on an algorithm (not the camera icon) to watch an animation of it.
