    15 June: Color scheme now adjustable from http://cubefreak.net/site/colorscheme.html
    16 June: Cleaned up color changing code. Cube color now also adjustable.

    Advanced F2L

    Actually, I haven't yet included things like R'U2RDw'RUR' that include a rotation or a double layer turn in the middle.

    Orientation-Preserving F2L

    Jeff2L

    and more random stuff.

    Tell me if there's something that should be on these lists!

    I like those rotationless insertions. Very nice.

    Awesome! Thanks

    and does anyone know where I can find algs from Nakajima, apparently they are very good.

    Macky, first let me say that this is an amazing resource! I will surely be spending lots of time looking at this site with a cube in hand!

    However, I think I may actually have an alg execution to add to your list! It's the same alg, but I do it slightly differently.

    For Jeff2l in the "Edge in wrong slot" cases the following case:
    zULF'L'U'z'

    Can also be done as:
    L Uw L' Uw' L'

    :)

    I like a lot of your open slot solutions, very cool. Thanks for all the work.

    Thanks, Chris! I made that the main algorithm. I was planning to add y'F'R'URF = Rw'Uw'RUwRw, which is the double-layer version of your execution.

    Added new algorithms, especially from these sources, with appropriate citations:
    http://speedcubing.com/f2l_advanced.html
    http://www.speedsolving.com/forum/showthread.php?p=172749

    It's been pointed out elsewhere that, compared to how much effort we've collectively put into optimizing last layer algorithms, there has been surprisingly little development in F2L algorithms for many years now. My view is that a thorough review of F2L should be one of the main tasks for today's CFOP community.

    I already have a lot of algorithms (including those that are not documented anywhere else), but I'm sure cubers here have more tasty ones. Please post them.

    I just started learning F2L and this is so extremely useful! Thank you! And sorry for the extremely n00b question but what does 'w' mean in the notation? Rw for example. Haven't seen that notation before.

    w stands for "wide" and means a double layer turn. Rw would be turning the right face AND the M slice 90 degrees clockwise. It's more common to see lowercase letters used for double layers in the US.

    Rw = r
    Rw'= r'
    Rw2=r2

    I personally prefer lowercase letters to w's, less clutter in algs
