A Faster F2L Look Ahead Technique (CFOP)

[@JPerm]

0:00 How 1:11 Recognizing cases faster 3:48 Save rotation time 4:20 Corner in opposite slot 5:48 Predicting first pair Recognizing orientation is not ALWAYS better than matching stickers or any other way. A lot of my recognition comes from "intuition" or "I just know", but the orientation technique is the best way I can explain where that intuition actually comes from. For predicting first pair during inspection, this recognition technique is the #1 reason I can do it in under 15 seconds.

[@junting605]

Thanks!

[@krishvijay1264]

Hey J Perm I am sub 40 and I use 4LLL and take around 5 sec for cross, 25-30 seconds for F2L, and the rest for OLL and PLL(It is my first month of cubing.) I have watched about every video I can find that says how you can improve F2L but still I can never. I am sorry that I have asked this question about 2 times before and you always answer so thank you but I don’t know what to do now. I really like cubing but I might end up quitting because I can never improve.

[@creepcrafting56]

What you need to do is to completely stop timing yourself, and just practice F2L, by just doing cross, and finding more efficient algs. LazerMonkey's every F2L case explained intuitively is a great place to go to. Other than that, example solves the only way to go. Apart from J Perm's Best Algorithms for ALL advanced F2L Cases pdf

[@29sav]

Krish Vijay it takes time to improve. If you've only been cubing for a month thats nothing. Keep practicing and learn full oll, pll. Good f2l comes with time.

[@zaakirmiraj8876]

J perm,can u explain wht is oriented,i dont understand ,u was saying the word over and over, and iwas like ,dhek is tht

[@yeet3279]

This is the exact technique that I have been using for months. When I was experimenting with cfop it just came naturally for me because zz relies heavily on edge orientation.

[@JPerm]

same here, except roux for some reason! I saw eo naturally after switching back from roux a long time ago.

Lol. Me too, I thought this was something everyone already used.

[@AjetovsKi]

What's funny is that I actually use the top color to recognize a good/bad edge faster. I initially used your method of recognition, but I found myself glancing left and right too often which was somewhat tiring. So now I just look at the top color of the edge & the front center color facing me. They must be the same or opposite, else I rotate! But thanks for your videos anyway...they're super helpful ^_^

[@Betadesk]

This makes more sense to me since you can always see the top without having to glance at the sides

Wow, amazing job continuing to create beautiful, short videos. I used to be a fanatic for the Rubik's cube, but then I lost interest. And now 8 months later, I'm thinking of finally putting some serious work into my F2L. Especially look ahead, which you so generously are giving advise on in nearly every video.

[@JPerm]

CrazyBadCuber, Hi

[@landular7057]

True, but I never used it.

[@higgledypiggledycubledy8899]

This is immensely helpful, thank you! And it made me realize that this also applies to an edge that is in a slot with the corner on the top (i.e. if doing an R or L move to bring the edge up makes it a bad edge, then a rotation is needed). Brilliant stuff

[@peripateticguy55]

When you get that sexy 10 second solve with flawless F2L look-ahead and a J-Perm.

i got a 9.05 single with an x cross, 2 free pairs, oll skip and ended up with j perm sheeshhh

[@The_Original_Rtxyz]

for me if my cross is efficient and fast it for some reason affects my solve a bunch, if I have a mid cross solution I get around 20 seconds, a good cross solution around 15 seconds, and a bad cross solution around 25, even if the cross doesn't take that much time

[@MuhammadJunaidJD]

5:05 you could do U' and a lefty sledgehammer that pairs them up and then R' U2 R to insert it without having a cube rotation ;)

[@EduTradeStudio]

Wow !! ZBLL on last solve before ending

[@daneilyan6419]

This is sooo god it’s what I needed to start being color neutral

[@danetyvoll797]

If you have a bad edge, you can pair them up and then insert using f R' f'. I saw it in Feliks Zemdegs 3.33 solve. Still really helpful! Thanks!

[@AndyFischer]

yeah any F move can turn a bad edge into a good edge. Doing a cube rotation with RUL moves is usually considered faster than doing F moves. But you can definitely use F moves if you want

[@twistiicuber1055]

[@tubeytubetuber]

[@AlexMartinez-mq8rm]

A great video, thanks for remaking it! Can you talk about in the future about corned and edge biased? I found an excellent discussion in the speedsolving forum, the title is: "Most optimal way to find and handle Fridrich F2L pairs (Intuitive)"

[@JPerm]

I think using corners is very natural, but using edges first also works once you get the hang of this orientation thing, because you never have to re-recognise the edge later on.

[@nabranestwistypuzzler7019]

2:40 You don’t need to rotate right away. You can pair them up with R’ U2 R & then insert with a hedgeslammer on the left.

[@RP_Cubing]

Bro he also talked about RUL moves

[@owenchurch]

I love these vids plz do them more

[@chirag_2447]

Hi j perm i watched many video of felikes and in the video he said that this edge is oriented and this is not oriented and i did not understand that but in this video i got it thanks j perm

[@notusknot3002]

Heres something I found that usually helps to avoid rotations: when you have a 3-move insert but your pair will go into the wrong slot (i.e. your 3 move insert is for the blue-orange pair but the slot in front of you is the blue-red slot), where istead of doing a rotation you can sinply do a wide D or wide D’ to move the slot, and not the pair. However, this may hinder you lookahead depending on how far in to f2l you already are.

[@ratnakhan]

GCubes but that will require a regrip to do d move then another to execute. only one regrip with rotation

[@jayceoksiuta9082]

oh a perfect match! 4:37💖💖💖💖💖

[@ankitsahni7929]

Sir,to recognise the EO FASTER,YOU CAN LOOK AT THE FRONT CENTER AND TOP COLOUR OF THE EDGE PIECE ON THE TOP .IF IT IS MATCHING ANYWHERE ON TOP EDGE POSITIONS OR JUST THE OPPOSITE COLOUR YOU DON'T HAVE TO ROTATE AS IT IS ORIENTATION AND IT IS EVEN FASTER THAN LOOKING AT THE SIDE AS I THINK SO.

[@jasonm.9192]

Cool! I needed help with look ahead!

[@zacharytrudell2411]

This is great. I will put this into practice

[@thijsbeentjes4008]

The case at 2:30 I recognize that case by that the two colors on the top layer don't match, I see that the edge has orange on top and the corner will have orange on top after the insert, so that pair won't match up

[@VichevJr]

[@mthia]

nwm, he said this at the end, i was writing this comment while watching the video 4:00 i learned to use F and f to solve these types of cases this would for example be: aligning the corner and the edge and then F U F' if im inserting something into the back, i just use f R f' etc 5:00 here i would do: U L' U L U2 f R f'

[@겐지-k9u]

Thank you j perm

[@DraxDrummer]

Thanks jperm

[@somekid5532]

An easier ish but a little less helpful way of doing this is: if the side color on the edge is opposite of the color of the face you are facing, you will have to rotate to insert or use one of the two rotationless inserts. This is useful for me because for f2l I just focus on pairing the pieces up and then inserting, which may or may not be a bad habit.

[@asr2009]

with your way, technically we will have rotationless f2l(use wide f moves to insert in back)

[@benbaron8951]

For people struggling- try learning zz and doing a few solves, this will be much easier :)

[@jillengland5676]

JPERM, I think I 💜 u lol

[@nabranestwistypuzzler7019]

5:06 I just saw 2 reds & intuitively understood double sexy right away, and then I would do a d’. Is that why I’m still sub-30 after 19.5 months of cubing? I am starting to get sub-25 though, so I think I’m just progressing slower. However, I did recognize it right away, but y’ U’ is better because then the last pair will be in the front.

[@zhekarsarkar7121]

I LOVE U i got 2 sec less bcz of this tip. ahhh can’t wait for my better average if i master this😘

[@0buru0]

At 3:36 isn't that the same case as when you put the edge on the front? The red edge side still matches the red on the right of the cube. Did you mean to flip the edge?

[@colelacey2875]

Good info. A video of how wich sides yoy need to turn as not to undo a solved edge pair

[@deepghosh2299]

Great video! Really helpful. Can i ask what should I learn after full OLL?

[@JPerm]

nothing is necessary, the best would be practicing f2l and drilling LL algs. but COLL is definitely the best alg set after OLL

[@deepghosh2299]

how about full one look PLL? is it worth learning before coll

[@JPerm]

oh that should be learned before full OLL!

4:59 do U' and lefty sledge hammer 🔨 to pair up

[@QBAndo]

Very, very interesting video, as most of the stuff you create. I think it could be useful for me and I'm ashamed I never thought of it myself, as I know the basics of ZZ and Petrus. Just two comments. As others have already commented I'd put it as top color of the edge is either front or back --> oriented, instead of side color is side color, for example, if the edge is in UB I cannot see the side color but I can always see the top color. Of course, if the edge is in one of the front slots then it's front color what I need to check against front / back centers. Anyway, if I need to extract the edge from back right I will have to check on side color, which is the one I will be seeing, to know whether it's comming on top oriented or misoriented. And, also, regarding misoriented edge -> cube rotation, there might be cases where a sledge hammer to orient it could be an option as well if it is either inserted in a front slot or in UF. Thanks for your great content!

[@JPerm]

Glad you liked it! I personally prefer side color only because the side color can touch the side center as it moves, making recognition easier in many cases; less thinking. It's invisible when the edge is at BU, but the pieces are always moving so I don't think that's a problem. And you're right, avoiding rotations is definitely better when possible!

[@QBAndo]

You're absolutely right about both things I guess!
