Yes hello okay so I have starting learning Square-1 and need help memorizing parity and edge orientation. Any tips?

There's already a squan thread, so I assume a mod will merge this post into that one. Anyway, I'm kind of bad at squan so don't take my comments too seriously.

EO: The three main algs you should learn are I-I (1,0/-1,-1/0,1), L-L (1,0/3,0/-1,-1/-3,0/0,1) and 1-1 (1,0/3,0/3,0/-1,-1/-2,1/-3,0/-1,0). Notice that these three algs fully preserve cubeshape and none of them move the D layer by more than ±1, so you can just memorise the moves for the U layer and adjust the D layer when necessary.

The L-L alg is almost the same as the adj-adj EP alg, so if you already know adj-adj, you know L-L too!

Parity: Just use CPP lol. I haven't learnt any parity EP algs other than opp-H and H-opp.

Does anybody have any good advanced cubeshape tutorials (preferably not videos)? The linked site with the full cubeshape on the beginning of this thread has cut images, and I can't see the full chart.

Yeah I've never been able to see the whole of the CS page.

This is pretty much the same thing

Also the only reason I can't solve a square 1 without looking at a tutorial is parity. Not the memorization, but even looking at the alg, I still can't do it. Does anyone have any idea why?

Possible reasons: you're making some of the moves in the wrong direction or you're turning by the wrong amount for some moves. Step through the moves of the parity alg very carefully.

Alternatively, the alg you're looking at might just be wrong. This EP alg list has correct algs.

Hi guys I'm trying to learn advanced cube shape but it seems confusing to me. I watched Brandon Lin's video but I don't understand how to reduce cases I don't know to ones I know to ones I know.

Usually I either reduce my cubeshape cases into either scallop-kite or scallop-scallop. I usually only turn it into scallop-scallop when there is a lot of edge pairs but most of the time I turn cubeshape cases into scallop-kite by creating a scallop on one layer pairing up the edges in certain ways to create a kite on the other layer then doing scallop-kite.

Also does anyone have any tips on improving sq1 tps?

Anyone know of a way to generate scrambles for only cube shape, so I can more efficiently get better at cube shape? It'd be nice to not have to do a whole scramble just to practice a step of the solve.

Hi! i have a problem with sq1 notation. if an alg would be like /2 /-3/-1 etc. would -1 be one piece? and 2 2 pieces etc?

What's the easiest and safest way to remove edge caps of a Volt sq1? I want to try replacing yellow with black on my stickerless, but in removing the black edge caps on a broken black Volt i ended up breaking all the edge caps (luckily not the part I needed)

I'd like to be able to remove the stickerless caps without damaging them, if possible.

Just an idea I think I'm gonna try and wanted throw out into the forums:

For square-1, parity cubeshape is a thing now. The problem with it is it requires a ton of practice and knowing 2 algs for each cubeshape case. Instead, why not detect parity during cubeshape and then use parity CP to eliminate parity. From what I understand CP Parity's big downfall is recognition time so if you know you need to use a parity cp alg from the beginning then it should be pretty close in speed to normal CP. This also gives you the benefit of a backup parity detection step. If you messed up detecting parity in inspection you can still take a second to recognize parity in CP step before executing an alg.

I do think that parity cubeshape is probably going to ultimately be better but I think this may be a good alternative/intermediate step to learning PCS as it practices the detection and only requires learning 8 algs to begin with.

Any thoughts/opinions on this?
