I got a single PB in 2X2 in weekly competition :)

R U' R2 // Bottom
R U R' U' L' U R U' // Top ;)

Nice. That was the solution I came up with, too but I got a 5.39 because it took 2 seconds to identify the case.

I wish I could predict the OLL and cancel the R2 R into an R'.
 
Congrats!

I've got a 6.57 with that scramble, my fault, I just did the yellow face (and I had a skip too, but I'm slow) :o

Do you feel that R U R' U' L' U R U' is faster than R U R' U' R' F R F' ?

What thread are those weekly competitions that you always talk about? I would like to join!

Whenever I have a face easy enough to predict the OLL and realize that I can cancel the last move of the face into OLL I end up messing the solve because my muscle memory wants to perform the whole OLL and not just start on move 2 of it. But the very few times I manage to do it successfully it's a very rewarding experience! :)

Also regarding efficiency. Do you learn / perform OLLs in 2x2 in different orientations to avoid AUFing? I can do the F sexy / double-sexy F' ones and the sexy-sledge one with left hand and I'm trying to get confortable with sune/anti-sune from the back but most of the time I end up being slower than with U2 + OLL. I also use two different OLLs for the case with two oriented corners diagonally opposed (they are two common 3x3 OLLs). Any recommendations here?
 
Thanks!

I'm also in the Race to sub X on a 2x2... by the way, I've been practicing CMLL on a 2x2 like 30 minutes or so, and it's not that bad now, some algs feel weird but with little practice I think I will be faster than doing oll+pbl when I see I'll get a layer (by luck, I'm not going to try to build layers), for the rest I'll use Ortega until I (maybe) learn EG1/EG2.
 
I've created a small program to help practice BLD memo of letter pairs. It's just a windows exe file, and pretty rough and ready. In the download, I've included my letter pair 'input file' but this has a few references to people that only I know, it's just there to help you see how it could work before you actually make the decision to create a full list.

https://drive.google.com/open?id=0B6Fw_W6x0e8bZHBqeThvWGhGamM

To get going select the input file (path to file) by clicking the button with the 3 dots, then click the start button.
The way it works, is that you are expected to come up with the word in your head and then you can click 'I Know It'.
Note: this could equally work with a empty file list, just click 'Create empty file list' and use that as the input file.
 
As I mentioned before, I now have a Weisu 4x4x4. First off, I took it apart and mildly fettled with it to get it bedded in quicker. The I brushed up on my beginners reduction skills (one dedge at a time), which came back quite easily considering I haven't solved one since the 1990's. A change of technique to E-layer, rather than M-layer as the 'working layer' helped a bit, and after about 50 solves, I did a 2:23 solve, which nicely beats my 2:43 best from the '90's. Woot woot! So now onwards to more advanced methods. I'm starting off simple, Hardwick's "2 dedges at a time" seems a reasonable step, I'll look at the 'top' methods later. I have to admit it hurt my poor head at first, I'm sure Chris knew what he meant, but I was perplexed. Having a different colour scheme didn't help follow the example (it took me 3 attempts to correctly perform his example scramble!). But eventually it clicked. After doing a decent number of slow solves, I've got it mostly sussed, and was most amazed to find I could sometimes solve all the dedges in under 30 moves. It was more like 80 with the basic method. I can see how a 40 second reduction stage is possible, like Chris H says.
Needless to say I'm slug slow at it at the moment. TPS = 0.3. "Insane TPS !" I guess I should target the 1:30 competition cut-off time as a goal.

It's more fun than I thought it would be, largely due to the reasonable turning action of the Weisu. Goodbye, old Revenge.
I'm going to get some different stickers for it, though, fluoro orange, especially.
 
Low 2 mins already. Well done.

I'm slowly adding some comms to my advanced M2 and was wondering if anyone had alg lists they could share? The ones I'm really interested are those on the M slice. I'm happy with AC and CA but I'd like any others that are available. I know I should be able to work them out but I'm struggling. Thanks in advance.
 
I have managed to solve my 2x2 blind so far, haha. Just practicing corners. I have been watching Noah's videos, but there's one thing I'm having trouble with. So, is it right that you just need a memo letter for each PIECE rather than sticker? So the most you should end up with for corners is 8 letters or 4 pairs? I'm having some trouble figuring out when to stop. If you have 2 corners (or edges) and it just keeps going back and forth between them, do you just do only one letter for each piece? Like at the end of this one in Noah's video, when you do QOA, how do you know not to include V on the end, or not to leave A off the end? Because once you do QO you've touched all of the pieces, but you go back one more time for A, but not again for V.

Sorry if that's a dumb question or confusing! Hopefully someone can help!

Also, cubing impresses some of us! It doesn't impress my partner though, but he's not much of a geek :)

For the letter scheme there is a letter per sticker, so 3 for a corner piece, 2 for an edge.

Yes, you only need to memo for each piece, not sticker, but it could be any of the 3 stickers for a given piece.
If you have no new cycles, then there will be 7 letters to memo. 8 is fairly normal with just 1 new cycle.
So to know when to stop, you can place a finger on the piece once you have placed that into your memo. BEWARE though, when you start a new cycle, you DON'T add that piece. And you have to start a new cycle if you reach the buffer piece or if you reach a piece you have already memo'd. When you have a finger on all 7 corners, you're done.

Here is a tool you can use to double-check: http://di-mare.com/scrambld/

Usually you only hit each piece once, but when you break into a new cycle you will hit that piece again. You break into a new cycle if you hit the buffer piece before all other pieces are solved. In that case the buffer piece is brought to the buffer location and you have to temporarily put it away somewhere else, in any unsolved location, where it will remain until the piece that is supposed to end up in that location reclaims the spot.

What happens in that video is that with 'I' he hits the buffer piece, so after solving 'I' the buffer piece is in the buffer location where it should eventually end up. Then he has to put it away somewhere to continue, so he shoots it to an unsolved piece, Q, and picks up the piece from there to continue. Eventually he finds the piece that is supposed to end up where the buffer piece now is and shoots it to A. This brings the buffer back to the correct location.

Not sure if this explanation made any sense, hard to explain... The best thing you can do is to do that solve sighted, take note of the buffer piece when you get there, how it is put away and eventually brought back.

Meneghetii - Brazilian NR holder uses 3cycle with DF: https://docs.google.com/spreadsheet...mYleiLUnWuUUIWf4aTPQkj0bg/edit#gid=1308739601

His algs are really fine. I took few corners from him.

I was looking at this list when I posted but was having difficulties with an alg. I thought I didn't understand the notation but it turns out his x' was my x.

I'm such a long way off learning corner comms. I think I need a good YouTube video.

I think his notation is correct - I had no problem with doing his algs and find no mistake. If you want yt tutorial, I've learnt from this:https://www.youtube.com/playlist?list=PLF2ahQ91omyTosrOeYYsJJcQzhJD6rr9Z

And I had few lists, like Noah's or Meneghetti. But I started from doing my own. After few weeks I've checked all algs, to find better ones. At the moment the list is complete. I can share it, but I'm not using speffz.
