#Looking for simple tips to speed up cross and F2L

Hello everyone!

I learned the 10 misoriented pairs cases F2L algorithms, and I am looking to speed up cross (I do really basic insertions) and, especially, F2L.

I have other hobbies, and especially, school, so I don't want to spend months learning multiple F2L tricks. I think there could be a way to speed up (looking for 15 seconds average in a few months), just by learning a few simple things. Except TPS and rotation things, which aren't the most necessary things to learn for now. First video is a cross and F2L solve, scramble is:

F2L D2 R2 D2 L B2 L' R2 U2 R' F2 U' F' L' F L2 U2 R2 F D' L2

Second and third videos are cross, and F2L solve again, but separately. Scramble is:

B R2 U' L B R' U2 R2 F R2 B' R2 B L2 B L2 U2 R2 D F

Sorry if there's a mistake, I may have made a wrong move while scrambling. Probably not, but I just want to tell you in case it is.

Thank you!

solve multiple pieces together for cross and see how you can influence pieces
stop doing the d move thing and just rotate. Those are probably the easiest things

#

also for sub 15 you need to learn a lot of f2l tricks. The tldr is just that when you split pieces up/take them out of slots you do so in a way that you get a 3 mover

I see. Thank you for the tips, I'll check that out

#

Especially tldr, which sounds really interesting

#

f2l is very much overcomplicated but that's all it is

#

good f2l is just setting pieces up to 3 move inserts in as few moves ad rotations as possible

#

there is not much to it

#

also for cross, jperms vids and practice

orchid glade
#

I see

#

Thank you! How much time could it take me to get a reasonable F2L time for sub-20?

frigid lynx
#

depends on how you practice and how much you practice

orchid glade
#

Let's say, 30 minutes a day

frigid lynx
#

like i do say it is very simple, and it is in concept but actually learning everything is far from it

frigid lynx
#

if you'd like, i can talk through my thought process/approach for the first scramble you wrote so you can pick up on a couple ideas/themes which may reoccur

#

I started cubing almost two months ago. I will learn Two-Look OLL, full PLL, and improve F2L and cross

frigid lynx
#

sounds like a good plan

sure gimmie like 30

#

for the first cross, immediately I see that the blue and green edges are correct relationally (their centers are opposite each other, as are the pieces). This means i don't have to move them around/influence them at all
The next thing i see is that the red piece is already solved and the orange piece, to put it in D is just 1 move away (R' when facing blue)

So my cross is as follows:

x2 R' D' // insert orange and move edge to then insert green and blue where they belong
R' L2 //insert blue and green edges
D' R2 //solve those pieces and insert last edge

I left red till last since its already solved. with cross its best to get annoying pairs out of the way. In this case the best cross was also an xcross but this just coincidence

after this the first pair i see is the green orange pair. The edge is misoriented so i need to rotate. I rotate in such a way that the pair goes into the back slot since it makes finding pieces easier., so i rotate to face red. Since both of the top colors are matching, from this angle i can do R' U2 R to pair them followed by U2 R' U R to insert

Now i have 2 pairs to solve, red blue and red green. the red blue edge is misoriented and stuck in a slot, this is an annoying pair to do so i'll avoid it and do red green instead. As you know the solution here is U2 R U' R' U R U' R'

finally last pair, the edge is misoriented so i rotate and this is the same case as the previous one

#

x2 // inspection
R' D' R' L2 D' R2 // xcross
y R' U2' R U2 R' U R // 2nd pair
U2 R U' R' U R U' R' // 3rd pair
y' U R U R' U R U' R' // 4th pair

for cross and f2l this ends up being the full solution without the intermediate yap. LL is just LL so no bother putting it in

#

you can do the last pair well and rotationless but for the sake of simplicity i just rotate here

#

main thing here is just using eo to decide how and why i rotate in the way i do as well as inserting cross pieces relationally. this one is really important

orchid glade
#

Wow, thank you. I'll take the time to recreate all that, and see what you did. Thank you really much!

You can use cubedb to help visualize stuff if you’re confused with the rotation notation for example

orchid glade
#

You read in my thoughts 😆

I'll look for that, thanks

I just watched the first clip and it was painful lol

orchid glade
royal crescent
#

so many d moves to "avoid" rotations

orchid glade
#

Yeah, and these were badly made

royal crescent
#

well, you don't need to regrip for R moves

#

and as Luca said, always solving F2L pairs in the front isn't that great for visibility

orchid glade
#

Yeah, I see. What would you do to solve the problem?

royal crescent
#

for the regripping part, I'd recommend learning better ergonomics

#

your recog seems fairly bad, I'll chalk that up to always rotating to solve pairs, which appears to confuse you on seeing the pieces you already identified before rotating

#

I think Luca gave you some good guidance for that one

#

Luca also gave good advice for Cross, but to retread:
Solving one cross piece at a time is bad, as it adds both recog time and more moves

#

to mitigate this, I would recommend doing targetted cross training on sites like SpeedcubeDB and CrystalCube

#

and trying to force yourself to insert cross pieces together as opposed to the glorified beginners method cross solutions I assume you do often

#

correct me if i'm wrong though

#

F2L should always be the step that takes up the most time, ye

orchid glade
royal crescent
#

your cross in that first clip was a third of the clip length

orchid glade
royal crescent
#

like in the orientation order and such

orchid glade
royal crescent
#

like if you solve Orange/Green first, do you tend to immediately start filtering for Green/Red, even if neither of those pieces are in the top

orchid glade
orchid glade
royal crescent
#

that's fair

#

unless you're insanely unlucky, most of the time there should be at least 2 F2L pieces in the top to latch on to

orchid glade
#

So you would do this pair first?

#

I think I'll learn the edge in slot cases to improve these cases, instead of putting them out and pairing them up

royal crescent
#

sounds like a plan

terse bane
#

U dont have to do wide moves u can rotate it's faster and better fingertricks

orchid glade
#

Yeah, I've heard of that, thanks!

try to focus on speeding up ur cross and F2L this is the best tip i can give you
