So as I am sure my fellow cross on lefters (or the rare righty) have noticed, we are few in number. There are no tutorials for cross on left, and a majority of the advanced f2l tricks cross on D solvers use translate poorly to COL. As a result, many of us have independently developed our own tricks, rarely getting a chance to share them with one another. After Macky's challenge to cubers to push F2L to it's limits, I realized that almost of all the developments he made (and likely most developments to come) are useless to me. After talking to Phillip Espinoza a few days ago I realized that we have so much to share with each other, but no place to do it. So I thought I'd move the discussion from his facebook wall to this forum.

A good place to start:

Phillip's general f2l algs

Leyan's algs

I don't have the time or energy to generate images at the moment, so just bear with me and do the inverse to figure out what this stuff does.

1 Empty Slot algs:

F R U R' U 'F'

F U R U' R' F'

U r U' r' U'

U r U r' U'

L2 U' R' U M2 U' R U

r U' R' U r' and inverse. Really anything in the moveset <r,R,U> that follows this general pattern is a great way to keyhole stuff.

2-3 Empty Slot algs:

M2 U2 M2 U2

M' U2 M U2 and inverse etc

Single Slot algs:

F' R U' R' U R' F

U R r U' R' U r' U'

r U r' D' r U' r' D (fingertrick like Eperm)

U R' U' F' U' R' U2 R U' F (Indexpush F', can do Bw instead if its last slot)

I'm aware this is not much, but it's a start. Hopefully word will get out to the other COL solvers and we can get a good list going.
