The Petrus-W Method is a method for solving the 3x3x3 cube invented by WarriorCatCuber in 2020. The method is a variant on the Petrus method and is efficient enough to be used for advanced speedsolving.
Contents
Steps
The steps are as follows:
- 2x2 : Solve a 2x2x2 block in the back of the cube
- 2x2x3 : Expand the 2x2x2 block into a 2x2x3 block, also on the back of the cube
- EO : Fix the misoriented edges on the cube with ZZ-style EO (Edges oriented relative to where it belongs on the U, F, and D layers)
- L2P : Solve the final two corner-edge pairs while only using R, U and L moves to preserve EO. This leaves the last layer and the Down-Front edge piece to be solved
- COLL : Solve the remaining 4 corners using COLL
- L5EP : Permute the final five edges with L5EP as in Portico
Pros
- If you can look into the 2x2x3 block in inspection, no cube rotations are required
- You can orient 4 edges at a time, instead of being restricted to the 2 allowed in Petrus
- You can use M' U' M to orient edges unlike in Petrus or ZZ
- L2P has less regrips than in Petrus F2L
- During L2P, you get to use F2 and M' U2 M, which gives you a lot of freedom.
Cons
- Unlike in the ZZ method, you cannot look into EO during inspection time
- L5EP has 7 more algorithms than EPLL
- Unlike in Petrus or ZZ, you cannot use ZZLL or ZBLL to complete the Last Layer in one look
History
Petrus-W was originally proposed on the SpeedSolving Forums by user WarriorCatCuber on February 6, 2020. According to the creator, the idea came from a misinterpretation of another user's critique of a solve with the Petrus Method. After some thought and improvement, WarriorCatCuber decided to show the other forum users his new idea.
