I still use non advanced f2l; is there a way to know which of my solutions is slow? my general feeling is that the cases where I use two cube rotations is too much and I should ideally try to limit those.

Also, for theory purposes, is there a list of all possible f2l cases? that is every corner location, every edge location, and every slot to insert to and every free slot combination.

Two rules of thumb:
1. At most one rotation.
2. At most 7 moves (not counting AUF at the start, not counting rotations). Note that two triggers with an AUF in between is 7 moves.

There are some F2L cases where the ideal solution is to break one of the two rules above, but most of them fit the above.

I have not been practicing Fridrich F2L more than a few weeks. I wrote these personal notes for helping myself out getting better. if you have any thoughts feel free to post them. my biggest problem is to spot the two pieces (looking ahead). putting them together is really intuitiv when you...

(y) R2 U R2 U' R2 U R2 U' R2 (alternatively R2 U R2 U R2 U' R2 U R2) is by far my favorite, I can sub 0.8 it consistently and occasionally sub-0.5 it Lol I knew this on square one but never applied it on 2×2. Thank you!
