[Help Thread] Lookahead Discussion

I'm sure that teller knows this, but to make this more clear, this is because corners can be solved without cube rotations.

Any piece can be solved w/o a cube rotation...

No one actually uses B and F turns during F2L in a speedsolve do they?

I know that you really just say things like this on purpose, but I'll go ahead and get more specific for you.

Each corner can be solved using (only) the L or R faces, sometimes edges cannot (without rotating the cube, or doing d/d' turns). I hope this appeases you.

They are exceptional, but definitely, yes. For example, a sledgehammer R' F R F' does more than just insert a pair, it flips the edges at FU and FR. That could very well make the next F2L pair "better" if the edge happened to be situated there.

a sledgehammer R' F R F' does more than just insert a bad pair

A sledgehammer doesn't insert a bad pair, does it? It just flips the edges around it.

Oops...I misspoke. A sledgehammer inserts a pair (run it backward to setup and see), but it's not a "bad" pair.

I know - I use sledgehammers to orient LL edges quite a bit.

Does anyone use F/B moves in any other F2L situations, or does everyone rotate?

 

[macky]

In some cases, double-layer turns change F/B to U and avoid rotation for the bad edges.

random thots. Is usage of mirrors banned??

Yes.

A5b) While inspecting or solving the puzzle, the competitor must not have any assistance from anyone or any object (other than the surface). Penalty: disqualification of the solve.

F2L Look ahead help

I often find that when I am practicing look ahead that some of the corners and/or edges may be already inserted into f2l slots(but not solved or in the correct one) so after I finish the current F2L pair, I have don't have another one to solve because I couldn't find it. These are out of view for the entire time I'm solving the current F2L pair.

Any tips on how to fix this?

y or y'

 

[SpacePanda15]

Yes but should I do that in the middle of solving th F2L pair or should I do it after.

 

[Jorghi]

Do it at the most efficient moment xD

 

[SpacePanda15]

Usually if I do it after, I have to pause for a few seconds, and If I do it during the F2L pair, It causes me to just rotate back because I can't solve it from that angle.

 

[Jorghi]

What is your current average??? I don't think look ahead would help you as much as inserting f2l from different angles.

But I think some angles are slower to insert than others so sometimes a couple of rotations are good.

 

[SpacePanda15]

Nononono that's not what I mean. I mean having to use B or F or something to solve it.

Edit: BTW my average is anywhere from 25-35 because I'm learning full pll(I put it off for a long time)

 

[Jorghi]

Thats what I meant, those are a little slower because you use those to orient the edges. Nobody can make you master look ahead, people can try to tell you how they subconsciously do it. But u have to learn it yourself from practicing until you can do it without trying lol.

 

[SpacePanda15]

Ok. I'm sure I'll get it eventually.
