PCMS method Information about the method Proposer(s): Kenneth Gustavsson Proposed: 2008 Alt Names: KC (Kennth's Columns) Variants: Columns first No. Steps: 2 mayor, 2+3 sub steps No. Algs: 63 Avg Moves: ~45-50 STM Purpose(s): Speedsolving

PCMS (pairs, CLL, M and S slices) is an advanced method for speedsolving using columns first, designed by Kenneth Gustavsson in late 2008. The method compromises between easy look ahead and low move count (slice metric), and the result is 'decent' for both parts.

Steps:

1. Columns
   1. Solve 4 CE pairs using intuition
   2. CMSLL (42 algs), something between 2x2 CLL and CMLL (see CxLL)
2. Slices
   1. Solve centres and the RD, LD and BD edges using intuition (3x centre/edge pairs actually)
   2. Solve the FD edge and the LL edges (see E35)
      1. Orientation (5 algs minumum but here you can add more to force easier permutations)
      2. Permutation (16 algs)

The move count is dependendant on how well the first step is solved, if you add some extra look ahead and pair up more than one pair before you start to place them you can get as low as 10 turns for all four pairs at times. But if you are speeding 15+ is not uncommon and a sloppy done solve may give 20+ turns.
