Information about the method
Proposer(s): Reirto-RRNF
Proposed: February 2022
Alt Names: none
Variants:
No. Steps: 7
No. Algs: 16-264
Avg Moves: ~50-70 STM
Purpose(s):

RRBSP (short for Reirto-RRNF Belt, Separation and P3L) is a 3x3 method invented by Reirto-RRNF. This method was inspired by Belt, Square-1 Vandenbergh and ECP method

Steps

  1. Pseudo EOBelt: Orient all edges while putting E layer edges to E layer
  2. 8CO: Orient all corners while preserving the Orientation and Belt. This step contain 191 algorithms. Another way to do this to orient 2 corners and put it to D layer and then do 6CO which has 71 algorithms or Orient 4 corners and put it to D layer then do OCLL which has 7 algorithms
  3. Corners Separation: Put corners on it layer, it can be done intuitively or with 7 algorithms
  4. Edges Separation: Put edges on it layer, it can be done intuitively using M' U2 M, S R2 S' R2 and it mirrors or with 7 algorithms
  5. CPEA: Solve the corners permutation while solving Parity. This step contains 35 algorithms
  6. EP: Solve U and D layer edges permutation. This step contains 24 algorithms
  7. PES: Solve E slice/Belt edges. This step can be done the same like Roux L4EP

Step 5, 6, 7 are referred as P3L

Variant

All ECP P3L variation can be used for this method since it the same

Example Solve

Scramble: D' R L2 D F B U2 L U' F B2 U2 F' D2 R2 D2 B' U2 B' D2 L2

U F' R L' D2 F' R L' U L // Pseudo EOBelt
R' F2 U' D2 F2 U D2 R // 8CO
D2 R2 U' F2 // Corners Separation
U' M' U2 M // Edges Separation
(R L) U2 (R' L') // CPEA O/O+D
U2 M2' U2 M2' U S' M' U M U2 S // EP Ua/Ua
R2' E R2 // PES
E2' // AEL

56 HTM, 46 STM

Kinda easy scramble

D F2 D2 F D U R L' D' L // Pseudo EOBelt
(D' U') R2 U2 R' U R' U2 R U R' // 8CO
U' R2 U R2' // Corners Separation
S' U2 S M U2 M' //Edges Separation
(D' U') R D' L2 D L' U2 L D' L2 D R' // CPEA A/A+D
D2 M2' U2 M2' D' S' M' U M U2 S // EP Ub/Ub
R2 E R2 // PES

71 HTM, 60 STM

Pros

  • Rotationless
  • Good Ergonomics because EO
  • Can be high TPS because mostly algorithms if Corners Seperation and Edges Seperation algorithms learned

Cons

  • P3L recognition requires looking at at least 3 sides, which is slower than 2-sided PLL recognition or CLL recognition
  • Permuting the E slice either requires either E moves, or a rotation
