The original CP (corner permutation) First method was created by Shadowslice based off Jaap's work on corner permutation and ZZ-Porky. It is not really a practical method and was more of a proof of concept as CP first methods were an entirely new concept.

Steps
Original Proposal
- Solve CP and a 1x1x3 in DL using a 3-cycle to help with planning FB
- Extend to a 1x2x3 using <RrMUu>
- Extend to a 2x2x3+EO using the same moves
- Finish F2L using <R,U>
- 2GLL
Implementing 2GR Style CP
- Solve CP and FB at the same time using the same recognition as from 2GR's CPLine
- Extend to a 2x2x3+EO using the <RrMUu>
- Finish F2L using <RU>
- 2GLL
Pros
- 84 alg 1LLL is reasonably good.
- <R,r,U,M> is very ergonomic.
- A fair amount can be planned in inspection.
Cons
- Lookahead is poor.
- CP can be a big drain in inspection.
- EO+ blockbuilding at the same time is hard.
- CP can take quite a few moves.
- It can take a while to get used to CP planning.
