Be sure to know the 8-movers good, and then look at every case and find out how to make them an 8-mover, but cancel one move. It's easier when you notice thazt they're always 3-gen.

Also, aside from the A perm A9, each setup breaks the "adjacent non-interchangeable" pair, and by breaking it, it allows the moved corner to be interchangeable with the other corners after both a single and quarter turn.
ie R'U2R'D2RU2R'D2R2, R turns break UBR and BUL, R' makes it interchangeable with BUL and R2 makes it interchangeable with DBL.

Wow. This is exactly my mindset when finding A9s. I just couldn't articulate it.

TuRBo corners algorithms? or is TuRBo corners not a good method and I should learn BH?

 

[RyanReese09]

Turbo corners isn't a good idea. Just use BH.

When using comms for 4BLD centers, how do you recommend memorizing it? Letter pairs are usually nice for 3-cycles since I don't have to memorize the buffer, only the next two pieces in the cycle; one image per cycle. But when the buffer gets fill and I have to change to another one, things get tricky. Right now I'm just remembering, without letters (visually?), when a 3-cycle solves the buffer (2 piece swaps are obvious) and where the next buffer should be (often the next piece in line is already solved so I need to skip ahead). It just doesn't seem like the quickest or most reliable strategy. I could include buffers in my images, but that would throw off the 1 image for 1 cycle correspondence. Is there a better way?

@nickvu2: Whenever the buffer center solves in big cubes BLD I always just shoot it out to an unsolved location. If the buffer center solves with the buffer color (and you have other unsolved buffer layer centers) then just shoot to another buffer layer center.

Example: My x-center buffer is Ubl. If the buffer solves, but I have an unsolved U layer center location, then I shoot the buffer to that location.

If all of the buffer layer centers are solved, then shoot to some other unsolved location. However, when this happens you must remember to shoot to that location a second time when that cycle is done to close the cycle. The reason you don't need to shoot a second time and close the cycle when shooting to a buffer layer center, is that shooting to a buffer layer center is not breaking a new cycle. Doing so is just solving a buffer layer center, it does not count as a true cycle break.

I don't know if that made sense the way I described it, but that is what I do for big cube centers. The cons are that I use up to 2 commutators more to solve centers this way compared to using floating buffers. The pros, in my opinion, is that memorizing this way is far easier than using pseudo buffers for centers.

for any of you BLDers that wear glasses do you keep them on while memoing and take them off when solving or what do you do?

Sometimes I take them off when memorizing, sometimes I leave them on. If time is a critical factor (like in single BLD), I'll definitely take them off, though.

Haiyan used to wear glasses while memoing and he got sub 50 times. He took them off during execution.

he doesn't anymore obviously.

BTW,Blake, have you got you're first BLD yet? If not I can help in Dublin if I can

I wear my glasses for multiBLD, and sometimes I've worn them for 4bld and 5bld, but I prefer not to.

I need to train my parity for 3BLD, is there any online scrambler with the option "gimme a scramble with parity" or similar?

hey there
im the same way i just got into bld solving with old poch, for edges, and i use a Y perm for the corners, using letters for the edges and numbers for the corners, i have gotten the edges fairly quickly once i learned the t perm, and i incorperated part of the turbo edges or m2 for the UF and UB edges, so i wouldnt have to remember the j perms. it leaves only having to worry about using 2 algs thats it.
my memorizing time is about a minuite the way i started was to do the edges in steps to train my brain was i did like 4 at a time solve them, then do another 4 then the last four, glancing between each set to make sure i was in the right direction, then moved to 6 edges and then 8 all the way up to the possible 11/12 and now i can do all the edges every time, thought im not very fast.

i started working on the corners this week, but their alot harder due to the 3 sides to remember now. but im getting there 2 or 3 at a time till their all done.

the thing i think you can try like i did with the edges was to go through a scrambled cube, and write down the letters in order as they come up when you solve them one by one. then try to incorporate a word to each letter to make a sentence and go from there i caught onto that method pretty fast to where i can now execute sovling the edges with out having to peek. and do it in groups and work your way up till u have all of the words memorized.

I applaud you on your work. It's nice to see somebody who thinks for themselves (honestly, I never thought about avoiding Jperms like that for OPedges). Keep practicing, and you'll get better and better. As Chris is fond of saying, all BLD practice is good BLD practice.

Now, I have a question. Was there a question hidden in there that I missed? Because I can't find a question mark, and this is the question thread. Haha.

I guess he was trying to help someone then

the thing i think you can try like i did

Maybe he misinterperated porkynator's question

You could count the scramble's quarter turns. If they're even, just add a U at the end.

Thanks for the tip, I didn't know about this

Thanks, Chris!!! I never thought to do this! Practicing your strategy, I came across this case that I'm not seeing a good solution to. Any ideas?

Ufl (buffer) -> Ubr -> Dfl

 

[cmhardw]

Thanks, Chris!!! I never thought to do this!

Yeah sure, hope it helps. Just keep in mind that using this strategy will mean more moves to solve centers than if you used floating buffers. I find this to be a reasonable trade-off for what I consider to be easier memorization.

Practicing your strategy, I came across this case that I'm not seeing a good solution to. Any ideas?

Ufl (buffer) -> Ubr -> Dfl

This case is done exactly the same way as a corner "columns" case in BH. I don't want to just give you the alg for this specific case, because that is meaningless. It's much better to understand the "columns" commutator itself, then you will know how to apply it to any case, including your cycle: Ufl -> Ubr -> Dfl

 

[chardison1980]

oops my bad i guess i can ask this, with trying to memorizing the corners, do the rotations really change at all or stay the same like the edges?
what would be a way to learn when to break into a new cycle for the corners? i also realized that its old poch, that i use for the corners from the eric limeback videos, and old poch for the edges from badmephestos videos.

 

[Erdos]

Not really sure what you're asking. For OP, you break into a new cycle whenever you solve your buffer piece. That is, if your buffer is UBL (like in Eric's video), you keep trailing the solution until you solve the UBL piece; this marks the end of your cycle. Then you start a new cycle; that is, you choose an arbitrary, unsolved piece (whatever you choose is based on preference) and continue.
