What if look ahead is not the problem?

[rubiknewbie]

What if I am looking ahead the whole time and still not finding the next pair at all even if I am not thinking about the current pair :fp.

The killer is when there is a corner piece at the BL or BR position and I spend half the time trying to figure out whether it is the bottom corner (white) or top corner (yellow) because the bottom color is hidden when I look from the top. And I spend more time deciding how to pair it.

Should I just bring the piece up to the top and waste 3-4 moves or tilt the cube to see its bottom color and risk losing all momentum?

I have the same problem as you man. So ive decided to use algorithmic F2L instead.

But as for your question, i think the look ahead makes it so that you don't have to risk it. Maybe instead, while your making your f2l pair, look for corners, and as you insert, look for edges.this will help with the risk of using the wrong color.

you get what i mean?


(333 post, lol)

Edit: And should be in the disscussion?

I think it boils down to knowing which pairs are inserted also, and therefor knowing which slots are even worth looking at - while keeping track of pieces with yellow on them. If you can keep track of that you should have a better chance of being "pretty sure" what peices are what, and as you go further along you have less a chance for error. So some of it is sorta taking a risk.

I dunno if that make sense.. I mean. It's not just knowing where the pairs are, it's also know where there pair pieces definitely aren't and just sorta reasoning out what 'probably is' the piece you need.

But I'm just a average 50sec solver so.. heh. Not the most qualified cuber to help. But, I too am working on it ... (look ahead)

I would say that lookahead is the problem. If you're looking ahead, you should know the color of every piece relevant to what you are doing. A quick fix though, would be to just do a Dw, Dw', or Dw2 move to see what color the piece is without ejecting it.

Then you are not looking ahead...

Try to go slow and I mean dead slow, also tilt your cube like crazy.
I used to exaggerate with my tilting and slow turning and it paid off.

+1

seriously.

Ok I'll try again. I am getting worse and worse at this thing :fp.

Lol, the thing you said about not being able to recognize the D color of that corner piece, you need to use logical deduction. Chances are the opposite colored corner was somewhere in the top layer, and if you saw it, then you could infer that the other corner was not that color. Also, what Forte said about just looking. Just a little tilt and you'd know.

If that happens then you should most likely be on your 3rd or 4th slot because looking for corners in the top layer is much easier. Most of the time this will happen when you've used all the corners in the top layer for your first 2 or 3 slots, though.
anyway, since you would be on your 3rd or 4th slot, there's really very few cases that come up, so you should just learn the 'hidden' colors.

Do R' U' R U R' U' R with yellow top/blue front. White cannot be at the bottom of that BR corner, because then red would have to be in the back. So white is in the back. Most of the time you will already know that that corner isn't yellow because you'll see that all the corners in the top layer are yellow. You shouldn't be looking at BR or BL corners (unless you memorized what those corner stickers earlier in the solve) if there are corners to solve in the top layer.

I know this is probably obvious, but after solving the first pair, why not rotate the cube and put it in the back left? That way you'll be able to see almost all the other cubies. LOL I'm such a nOOb

Because that's an unnecessary rotation. It wastes time. However, if you have the option to rotate the cube because a certain f2l case needs a rotation in order to solve it, then I would rotate the cube in such a way that the f2l slot gets solved in the back.

It is true that most of the time they are the 2nd-4th slot but even then I still get slower trying to figure out the bottom corners compared to when they are at the top.

Also I am trying to not always leave the bottom corners to the last because then I miss out using certain shortcuts like when the bottom corner is correctly placed and orientated (eg D R U' R' D').

that is the problem i always have but you just have to find a better way....

 

[guitardude7241]

that is the problem i always have but you just have to find a better way....

The answers are:
-practice
-go slow when practicing
-when practicing, practice F2L only
-start to use "d" and "d'" turns
