# Algorithmic F2L Guide

I made this guide to show how to solve F2L agorithmicaly.

It teaches the fundamental F2L cases (R U R' and R U' R') and how to transform the complex cases into the fundamental ones.

Note that it don't show the AUF between the complex and the fundamental cases so you have to have learned the fundamental cases before moving on.

Basically its a guide on the best order to learn F2L.

Have fun

D2a: R U' R' A2a
D1b: F' U F A2b
those are nice algs for that angle, but I will retain the hide edge and connect corner concept for consistency

EDIT: I put everything in one page.

Just out of curiosity, and I'm asking this as someone who isn't that great at speed solving, why would I insert H1b like that and not U' R' F R F' R U' R' ?
Or K1a with U R U' R' U' R U' R' U R U' R' ?
It seems like some would be faster just by adding an AUF move before, or am I wrong?

Wow, that's very nice. I like it. This is a very good reference for those learning intuitive F2L. Good work.

You first alg is nice on the FR slot but its hard to mirror to the other slots.
For example, U L F' L' F L' U L is not so fingertrick friendly.

There are many ways to solve each f2l pair and your second alg is just one of them.
And you are not wrong.

Thank you. It is nice to have feedback after so long time I posted it. :\

How about this alg (setup with R U R' U F' U' F): l F' R U' R' U l'.
The front-back mirror is (setup with L' U' L U' F U F' y2): R' U R' F R F' R.
And of course, you can left/right mirror these for all four slots easily enough. I don't use r' F L' U L U' r though.

I like to use the KISS principle.

Hmm.... Might have to try this out. I will compare it to what I do in intuitive f2l.
