How do top-cubers lookahead?

[SirWaffle]

I think the top speedcubers use Turbo Tracking.

(Take one corner on a cube, then follow that corner by doing a crazy hand scramble. Move the pieces very fazt)

Seriously wtf that makes ZERO sense!

It does make sense. Jskyler91 introduced this in his videos

Idk if I count as a "top cuber" (32nd in the world for avg) but I have definitely talked to a lot of the top cubers, and I have never even head of this. I don't see any evidence at all to support this claim.

There was a thread on here last year. It's pointless

Do you really think turbo tracking is a waste of time? I was planning on incorporating it into my practice to see if it might help me - but I haven't really tried yet so idk if there is anything to it. Seems like besides the initial response, the actual thread didn't get much feedback from those who actually tried it.

I just read somewhere that within 9 seconds of the inspection time (iirc), 5BLD can do the entire first block in his head, and "know where the second block pieces are", which I assume he means he can track both blocks completely in his mind, but not the 2nd block's orientation. Which makes sense... in my (VERY short) experience with Roux blockbuilding so far, corners' orientation are a ***** to keep track of mentally.

Unlike edges, where you can just remember the EO and the location (isn't this the basic technique for crosses? i.e. if we define cross EO as being placeable in the cross face in 1 move, and bad edges need at least 2 moves). Actually, with Chris Hardwick's tip earlier of keeping track of EO during F2L, I find tracking/prediction much easier for CFOP: just keeping track of ONE sticker on the corner, the cross-face colored one, along with the EO correctness of the edge (ZZ-definition), is seemingly enough to know the case (making it a bit easier to play out multiple pairs in my head during sloooooow solves, its just like following two dots and just purposely looking out specifically for F/B turns and rotations).

I wish it were as easy with Roux... no matter how slow I go, I keep on making mistakes. Especially with CO, one sticker seems to be not enough, it seems I have to keep track of at least 2 per corner just to know how its oriented. I can't believe 5BLD used to do speedBLDs with this... that's probably a factor on why he improved so fast (I can imagine that speedBLD + free floating blocks, requires developing insane tracking ability, especially with tracking CO, or finding a trick with it lol).

Also, did Feliks really make cross mistakes in the past? Along with that instance where he grabs a cube with both hands during an OH solve, I think this just proves that he tries to do an insane amount of stuff in his head during inspection time.

As for turbo tracking, well, jskyler is pretty fast so I wouldn't discount it (his guides are actually excellent). But just saying "pros use turbo tracking" and disregarding all the information given earlier in this thread, to me, seems... noobish and scrubby. He mentions the purpose to be to make tracking pieces easier i.e. more comfortable, and not frantic. And he mentions in that same thread:

interms of understanding how your moves affect particular pieces on the cube, however I think practicing multislotting* is a better exercise for that.

Also, I just watched jskyler's lookahead videos (I have no idea why I never noticed that before). In the "F2L to F2L" part, he talks at length about tracking a single pair, but he also mentions "prediction" at like a couple of minutes at the end. Rather, he was talking about solving two pairs in your head.

(*he's actually talking about solving two pairs mentally in his video, referring to it as multislotting... although I think I remember that actual multislotting was something else involving weird/specific cases and some algs).

I mean, if Lucas made the entire solve blindofolded in 8.90 seconds (lets just despise the memo time) its because he actually tracked all pieces in his head, or at least he knew where the pieces for his next step where gonna end up.
And during the solve, everything just flowed smoothly.

Just take your own conclusions. i find this very impressive. I think that right now I will just scramble my cube, find the optimal cross solution, and instead of simply applying it and finding my first corner-edge pair at once (just like everybody says to), i will try to guess where my pair will be before I make a single move. So that i make no pause at all, like a single algorithm.

this is hard to explain but i guess you got it

Didn't lucas just plan the whole F2L?

Yes, he tracked the pieces all in his head, which takes 35 minutes! This IS really impressive and almost nobody can do it. It is also not MUCH faster than his normal times, but it does show very well how much time he wins on needing lookahead

 

[aradhyaprateek]

Can we plan 2 pairs at once while solving the first f2l pair

Hi I have seen in a forum regarding f2l , it says that "try to plan two pairs at once in look ahead"
what i am doing is while executing first pair i am planning for the second pair so,is it possible While inserting the pair tracked from the cross, tracking the next 2 pairs

My average is around 30sec and i take 12-14 sec to solve f2l

Is it possible do do normal BLD memo, and lookahead? And CFOP?

What? Normal BLD is very very different from CFOP
