RRBSP

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
Contents
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 contains 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. P3L: Permute all 3 layer, it have too much algorithms so it splitted to 3-2 look, most recommended way to do it is CPEA>EP>PES
RRBSP-CPEA
5a. CPEA: Solve the corners permutation while solving Parity. This step contains 35 algorithms
5b. EP: Solve U and D layer edges permutation. This step contains 24 algorithms
5c. PES: Solve E slice/Belt edges. This step can be done the same like Roux L4EP
RRBSP-LBL
5a. PLLP/PLLCS: Permute 1 layer with also parity
PLLP: Swap DF and DB to solve parity
PLLCS: Swap DFR and to for solve parity
5b. PES: Solve E slice/Belt edges. This step can be done the same like Roux L4EP
5c: PLL: do z2 rotation and do PLL
Another P3L Variant
All ECP P3L variation can be used for this method since it the same

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
