VH method

VH method Information about the method Proposer(s): Lars Vandenbergh Dan Harris Proposed: unknown Alt Names: none Variants: ZB No. Steps: 3 to 4 (Cross, F2L+VHLS, VHLL/ZBLL) No. Algs: 78 to 525 VHLS: 32 LL: 46 to 61 (COLL: 40/42, PLL/EPLL+ADJ/DAG swap: 21/6) Advanced LL: 493 (ZBLL) Avg Moves: 50 to 56 Purpose(s): Speedsolving

VH (short for Vandenbergh-Harris) is a variant of the CFOP method invented by Lars Vandenbergh and Dan Harris. It orients the last layer edges during insertion of the final F2L block. It has exactly the same effect as the ZBLS stage of the ZB method, but uses much fewer algorithms - 32 VHLS algorithms as opposed to ZBLS's 125 (excluding mirrors and inverses). It achieves this by restricting the LL edge orientation step to the moment before insertion of the final F2L pair (in a similar manner to Winter Variation). With full ZBLS, LL edge orientation is carried out from any F2L last slot case.

After VHLS, the solver can use either COLL/EPLL (also called VHLL, which ZZ-VH is a namesake of) or ZBLL to finish the last layer.
