Nice explanation for 2x2. I'm struggling a bit with ortega. I'm improving but many cases I fumble through.
You said you keep your bottom bar in front. For me it seems that most of my algs are for bar in the back. Where did you learn your algs?
I often get messed up when top layer is solved. I have to completely rotate the cube to do T perm. I used to use J perm but I jam up on 2x2 alot. How does your upside down T perm go. My brain can't picture it.
also what do you use when you have only 2 diagonal corners left? I can't do Y perm fast. I hate when it comes up.
what's your inspection preferences. Do you always plan for a bar? Or do you also go for no bar or solved first layer?
I got most my algs from Chris Olson's / cyotheking site.
I also hate when I have a diag swap or bar on bottom and all of a sudden I get a solved top layer without wanting, that's one of the worst things of Ortega. My 4 algs for T and Y perm alternatives on top and on bottom are these (but I have to admit that I still use T-perm for adj swap on top most of the time because I get very few, see below why, and at times I forget that alg):
Diag swap on top: R U' R' U' F2 U' R U R' D R2
Diag swap on bottom. Same alg cancelling into R2 B2 R2 (or R2 F2 R2): R U' R' U' F2 U' R U R' D B2 R2
Adjacent swap on top (bar in front): R' U R' F2 R F' R' F2 R2 (U or other AUF)
Adjacent swap on bottom (
bar on the left): R2 U' R' U L' U2 R U' R' U2
The last one is the fastest of them all. I can try to film a fingertrick video showing how I execute it, if you want. Also, I try to avoid having a solved layer on bottom as much as I can, unless it is, by far, the easiest face I can see during inspection (and in that case I wish for a PBL skip
). Whenever I can see a face with bar or diag swap even if it's a couple moves longer than the layer I go for that.
