Well, I am not familiar with the 2GB method, but according to the introduction of the 2GB method, the 2GB method is similar to the RUP method.
And the RUP method is also my work four years ago.
The last 4 pairs in the R,U layers in RUP now have strict definitions and names on the PPW website...
This example scramble are white top / green front.
R' L' U2 D F2 D' B' U D' F2 R' F U2 R2 U' D' L' D2 F2 U2 R U' B R' B2
PPW solution example here use yellow top / orange front.
The total solution move sequence is
D' B' L U D2' F' L U L' D' U2 R' D U2 R2 D R D U R' U R2 U R' U' R D'...
On the final step (block guide), you can do two 2x2x1 blocks to cause the only one way to complete the entire cube. That is wrong.
In fact, you must do one 2x2x1 block and one 2x3x1 block to cause the only one way to complete the entire cube. I fixed that mistake on the PPW website, and added...
Sorry, there is a mistake of the end on the final step (block guide) of this method and I fixed it on the PPW website.
If you concern this method, you can go to PPW website to see it again.
Maybe the videos I'll make it again to fix that mistake if I have time to do so.
Because the PPW website is original writing in Traditional Chinese then translate it to English.
There is Traditional Chinese version of PPW website
Maybe you are more familiar with reading Traditional Chinese.
From January to March 2022, I have developed a new method for solving Rubik's Cube , tentatively called the PPW method.
The rough solution steps from start to finish are all carried out by bundling the corner and the edge into the pair. The moves can almost always be interchanging pairs...
I developed a similar method from the method I posted before.
But I only wrote the Tradition Chinese version article of the new developing method.
Temporarily call it PRUM method and use the idea of mirror reflection.
The step of new developing method are
Step 1, build 2 pairs.
Step 2, retain 2...
Because this method is a pure reducing group method.
So I change the steps name of this method like below.
Step 1, complete a 2x2x3 block
Step 2, Reducing to R, U face rotations group.
Step 3, Reducing to the group of retaining 2 pairs
Step 4, Reducing to the group of retaining 3...
I create a new method.
The first step of this method is to do a 2x2x3 block as well as the Petrus method, but all the rest steps is not the same as the Petrus method and this method is a group reducing method, reduced to the R, U face rotations group and the group that does not destroy...
