A New Speedcubing Method, the Tudor Method

[PapaSmurf]

I came up with this method in about September, and I’ve genned a few of the algs, although a lot remain “ungenned”. The steps for this method are as follow:
1. Build a 2x2x2 just like in Petrus.
2. Expand to a 2x2x3, but on left, so not like petrus (which does it in the back).
3. Solve all the corners: there are various ways, but the best are probably 42 style or waterroux style. 42 style is 42 algs, but can be extended to be 128 (or more). Waterroux style is 343(?) or more, but probably better. The sets for the waterroux corners are: CRLL (cll without regard to R face edges), LEG-1, TCRLL+ and - (if you have the twisted corner in DBR instead of DFR you can do D’ then D before and after the alg), TEG+ and - 1, TEG + and - 2. This time, it does matter where the twisted corner is.
4. Solve FR and BR. The algs used require good S slice fingertricks, but about 90% have been genned and they’re short and fast.
5. Do a y rotation then L5E. I’m not certain how many algs this is, but it’s probably over 100 and I think that it’s less than 300. This set includes ell and L5EP, which are both very good alg sets.

Movecount:
1. 6
2. 7
3. 13.5
4. 9
5. 10.5

This gives 46 moves, and if you have a tps of 10 (which isn’t a big ask for speedcubers these days) you will get 4.6s solves.

Advantages: low movecount, 3 algs steps give good tps, good ergonomics for alg steps (RS, MU, and CLL algs are all sub .9), lucky cases are very lucky. 6 move cll, 4 move FR BR and 3 move L5E.

Disadvantages: as there are 3 alg steps, lookahead is hindered, lots of algs, 2x2x3 can be awkward and is hard to completely plan in inspection.

I feel like this method, once mastered, could challenge the big four at a top level. And for someone who can do blocks well, it’s just a case of learn more algorithms to get faster.

Variants: instead of solving FR and BR, you could also either solve DR, or you could solve eo along with it. This would reduce the cube to either ELL or L5EP, both very fast alg sets, especially L5EP, although recog would be harder and could be worse.

Also, this method probably isn’t brilliant for one handed, unless you rotated to do all the FR and BR algs MU instead of SR, and even then, you need to rotate again to do L5E MU. Similarly, it won’t be good for feet or FMC due to the slice moves.

Spoiler: Example solve

B' D2 R2 B2 D' L2 U B2 L2 D R2 D B F' L' R' U F' R' U2 R2
x2//Inspection
U R' D' L D' F2 D//2x2x2, 7/7
y R D R D' R2//2x2x3, 5/12
y' U2 R2 U'//corner setp up, 3/15
R U R' U R U2 R'//corners, 7/22
U' R2 U2 S R' S' R' U2 R2//FR+BR, 9/31
y U M' U2 M' U2 M U M2 U M' U'//L5E, 11/42
This is a kind of lucky solve, although many solves like it can be expected.

Feel welcome to criticise and put your thoughts down below!

Or you could just use Petrus

 

[PapaSmurf]

True, but it's a less blockbuilding-y way for people who might prefer algorithmic solving. And all the algs translate to 2x2 (although not perfectly).

2. Expand to a 2x2x3, but on left, so not like petrus (which does it in the back).

Just pointing out, Petrus doesn't exclude any of the sides for expanding to 2x2x3. When I used Petrus I would choose whichever of the 3 possible sides I saw first.

Might sound nitpicky... but... well... no... it is.

Otherwise this sounds fun, as long as there's an intuitive way to get through the last couple steps. Otherwise, the recognition for L5E would make this an extremely difficult method to learn, even for fun.

 

[PapaSmurf]

Most of the fast people say solve the 2x2x3 in back to avoid rotations. Also, L5E isn't too hard. You can recognise it as the L5EP case plus flips, which is how ell is done, and that apparently isn't hard at all (from Justin who's sub 10 with cfce).

 

[Chree]

Sounds more like a general tip than a requirement of the method. But again, I'm being nitpicky.

 

[Neuro]

if you're really worried about L5E you could do it LSE style. Most of the cases have solutions that follow that structure anyway. Obv memorizing it as an alg would be better later on but if you just want to start using the method LSE style will be fine. I'm more concerned about the FR+BR step; S moves can be pretty tricky and recog seems like it'd be awkward. Otherwise if you can find a very good way to do corners and have good 2x2x3 times it should be a fine method

 

[Skewbed]

How does FR+BR work? Is there a method or algs for it?

 

[PapaSmurf]

There are algs for it, although I'm currently wondering whether to change it to DR-BR, as then you wouldn't have to rotate. I could send you the alg list if you want though.

 

[Skewbed]

An alg list would be nice, I am interested in learning this.

I know the Zipper method leaves a non-D layer edge unsolved and uses <RU> algs, but it also has orientation done. Would this L5E group use <RUF> algs?

 

[PapaSmurf]

It uses whatever gen is speed optimal. Same with zipper.
