'''VHF2L''' (short for ''[[Vandenbergh-Harris]] [[F2L]]'') is a step of the [[Vandenbergh-Harris]] method that basically does the same thing as [[ZBF2L]] 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.
