[Video] Set of FAST rotationless F2L inserts

[AvGalen]

Thanks for the tip! I am not sure if I can do it from that angle, though..

From another angle, it's L' U L F R U2 R' F', which is more doable for me. Btw, your yt page is very inspiring. You do seems to use a lot of tricks that are a bit risky when under pressure.

I've been playing around with some algs for F2L that I have not considered before. I am not sure if these are well know, but I'd like to share them:

This basic alg inserts a corner in the BR slot: R2 D' R U R' D R U' R. The regular alg is two-gen, but this flows very nicely when D's are done with the left ring.

A lot af variations can be made from this. You can also use a similar alg to insert an edge: R'UR' D' R U R' D R U' R

Or this pair: R2 D' R U2 R' D R U' R

Or this pair: R' U' R' D' R U R' D R U' R

I am really starting to like RUD algs

Joël has somehow gotten it in his head that RUD version of every alg are the best, even for A and E perm like this:
R' D' R U'
R' D R U
R' D' R U
R' D R U'
etc etc.
The sad thing is that it actually seems to work when you practice and practice and practice

R2' f R f' U' R' U R' is my favourite for that awkward F2L case.

That's not sad, it's great!

Well, I don't use it for E (except for fun), but as long as I have not perfected my D2, the 15 move megaminx CP style alg works for most A-perms . (Btw, the regular alg is RUD too.)

Such RUD craziness! I am not strong with these. I wish I could see them demonstrated properly/well.

Thanks, Joël. You and Dan Knights sort of got me going down this path in the first place. Fun!

A bit shorter: I use R (F U R U' R' F') U' R' for this case.
I find it quite easy to remember as I have it in a matched pair with R U R' (F U R U' R' F') R U R' for the alternate corner orientation.

That's really interesting. Short and sweet. I want to use my left pinkie on the first R. I might have to switch.

I had been doing this (and its inverse) for a long time, but lately it's been feeling a little wrong:

(r U' r') U2 (r U r') (R U R')

New video, 2nd case of three.

Again, the alternative is a cube rotation and pair construction--ouch! Intuitively, everything is wrong with this case, so here we go with the algorithmic move-count fix:

FR - r U' R' U R U r'

FL - R' F r U' r' F' R

BR - r' U R U' R' U' r

BL - l U' r' F r U l'

These are darn handy once you learn to recognize them, and low movecount! The alternative is a cube rotation and pair construction--ouch!

These take some time to incorporate into lookahead, but things like x' actually give you a free peek at the B layer.

F R U2' R' F'

F' L' U2 L F

x' U' R' F2 R U

f U R2 U' f'

These are fantastic! I've struggled for years with these slots, using awkward F and B moves to avoid rotations... These are smooth and flow well. I don't know how I didn't find this before now...

I'm going to get theae down...thanks!
