Lars Petrus has a nice page for explaining and showing the basic moves of blockbuilding:
http://lar5.com/cube/fas1.html
http://lar5.com/cube/fas2.html
http://lar5.com/cube/blox.html

For building the 1x2x2 block, try different strategies. For example,
1) pair corner with edge 2) put the other edge in place (not actual place, it's enough when its main color matches to the center), 3) pair them up for 1x2x2
or:
1) put one edge to its place, 2) pair corner with the other edge, 3) pair them up for 1x2x2.
Then pair the last corner-edge and put it in place to form a 1x2x3 block.
During building the 1x2x2, you can influence the last corner and edge (which will be the last part of the 1x2x3 block).

Also, Gilles has good examples for building the second block:

Experiment with different movements and pairing, and examine others' solves!

Nice GuRoux! What a beast!

Who is the second best Rouxer behind Alex?

So, here's my plan for memorizing CMLL, tell me what you think. Right now, all of the 2looks are about in muscle memory and take pretty much no thought, so I decided to start working on CMLLs. Over the weekend, I memorized all of the anti-sune CMLLs. Every few hours, I'm drilling all 6 of them, and when I do my non-timed solves, I intentionally set up an anti-sune case (by using sune on oriented corners), just so I get to practice one anti-sune case on every untimed solve. I'm going to do that for the next few days, until I feel comfortable, then I'll probably add Sune. Sune and Anti-sune I can easily drill back and forth, so that should be quite helpful. I figure every 3 or 4 days (or possibly a week, if I don't have time to really drill) I'll add a new set of cases, and within a month or so, I should have all the CMLL down. I know it's a bit early,but I think it will be better for down the road. Also, I don't really mind memorizing algorithms.

Nice. I don't use any right-dominant algs for Anti-Sune. I just mirror the Sune Algs on the left.

Nice, sunes are usually the harder sets of cmll, if you can through those the rest should be easy. Make sure your recognition is good and execution is smooth.

Thanks, yeah, that's what I'm focusing on. It seems like there's three stages. First is having the algorithm memorized, second is being able to recognize the case and recall the appropriate algorithm, and third is when you can recognize the case and apply from muscle memory without thinking. I have all the 2-looks in muscle memory now, and I never mess them up. Once Anti-sune is there, I'll work on Sune. I don't want to memorize the next set until the previous one is totally ingrained.

I think those who are really good at FB do it in average 8 moves, i do it 10. Usually takes 5 seconds of inspection, sometimes more. don't do it like cfop. try to do it in the fewest moves.

With [x2, y2] color neutrality, 7-9 is the most common. Above 10 is very rare.

Disagree. I like sunes and antisunes (B and C). I used to be hated Bowties (D) more. Grrr. Hard and long algorithms with choppy recognition (actually, not anymore, but I changed my D sets the most often).

Some of the sune/antisune algs are bad, maybe that's just my algs. But i think sunes and antisunes are definitely hardest to recognize.

I've got antisune recognition down pretty quick. It's a little annoying,cause you are looking at top side on the BL/BR corners and looking front side on the UL/UR corners. The only thing that will happen is I will see the B3 or B5, but it's actually a B4 that I missed. It's getting better though :)

Maybe it is because I use my own recognition system, which is close to Waffle's system (basically using the same principle), but I find mine easier to learn and adopt. Or Waffle's is overcomplicated. He uses top slash, bottom slash, bottom far, and far bar, and you have to look all of them, because some sune case can be recognised from this, some can be recognised from that. For examle, C1 = "Top Slash has Opposites Bottom slash has opposites", C2 = "Bottom Bar And Far Bar are opposites", and so on. However, in my system, I use the same two bars for all sune cases, the same two (although different) bars for anti-sune cases, and I found it even more clear how the case can be concluded from the colors of the bars.

Should I write about it?
(The only difference is B, C and D. For the rest of the cases, I use the same pattern recognition system as Waffle.)

I'd like to see it. More information can never be bad.

I've recently switched from CFOP to Roux, and I'm still having problems with block building. I average ~15 moves for FB and ~20 moves for SB.

It would be great if someone would post an example solve for FB and SB for this scramble. This one

Thanks!

You did the link wrong. I fixed it for you. I will do it in a couple minutes and I am actually going to make a video today about roux.

Hmm. Neither was good.
