Hi folks!

I wrote a description about my currently used BLD corner method. Someone taught me years ago, and since I can't find it (or similar) anywhere on the net, I named and published it.

You can find it here:

(EDIT on)

If byethost is unavailable, try this link:

Boomerang method

(EDIT off)

The description above is actually pretty detailed (maybe too...), contains explanations, advices and example solves as well.

Basically it is a preorientation-used 2-cycle method, which could sound horrible - however, through the nice and fast shortcuts, it is pretty fast. I found it well-balanced between the difficulties of the memorization, the executation and the number of algorithms to learn.

A 14 seconds example solve (no exception, no parity, some shortcuts):


Keywords:

  • Piece-by-piece / 2-cycle solving with fast algorithms such as (U R' U' R)*3
  • Many easy, handy shortcuts (make the memorization and the execution shorter)
  • Little to zero setups
  • Zero thinking during execution, minimal thinking during memorization
  • Short, permutation-only memo-queue
  • < 17 seconds to solve on average
  • 10-20 algorithms to learn / understand
  • Preorienting as disadvantage

Yes. I taught him. If I remember well, now he uses BH; which is a bit hard for me (I understand it perfectly and know all the commutator types, just extremly slow with it).

This is a great method, I soooooooooooo want to use it. When i do M2/Boomerang, i cant possibly see a way to deal with parity. What i need is a way to deal with parity, if any exist for M2/Boomerang BLD solving.

Edit:
If i would have just looked at the page, an exmple M2/Boomerang Parity Alg thing is given.

(I see that you asked 3 weeks ago, I still feel an urge to answer. :) Sorry for that. )

Yes, there is description for the M2/Boomerang parity alg, in the end of the permutation section. But for any other edge BLD method, a parity alg can be easily constructed depending on its side-effect and possibly in the order of the execution (corners-first or edge-first).

Yeah, finally I've found Boomerang home thread. I can do blindfold Boomerang and M2 separately but I can't join them, my memory is very very bad :(

Keep praticing, and if necessary, spend a little more time on memorizing.
Bond your memorized items to familiar objects / persons, like your family, favorite actor, pet, etc.
Also usually the funnier (weirder, obscener, etc.) things you have to memorize, the easier to recall it.

Alternate preorientation algs:
Case B (antisune): U' R2 U' (R' U R' U2')2 (R' U R' U' R2).
Case D (L/triplesune): [U2, R2 U' R' U R' U' R2] = U2 (R2 U' R' U R' U' R2) U2' R2 U (R U' R U R2).

First alg I got from CE, second alg I got from Brest :)

This looks really interesting, how nice is the transition to 3style?

Some of the shortcuts are already 3-perms, which can help you focusing 2 slots as next step. I would say that the transition to 3OP is fairly easy and straightforward. However, the transition to 3style could be a bit harder, dealing with orientation and permutation is a huge step.

I would say that from OldPochmann it is a good intermediate step toward 3style. Also in scrambles where the preorientation is easy, Boomerang / 3OP can be easier than BH (unless you are already a master of BH).

However, if you can already manage 2 targets at once, I'm afraid this method cannot bring you much closer to 3style.
