Any tips for sub-30 on 3x3 without learning too many algs?
Also, Tips For sub-5 on 2x2 with ortega?
Good luck on your progress!
I might as well give a couple tips here.
1. 3x3 sub-30:
-It seems like you already know 4LLL, but if you don't, learn that; it's not very many algs
From there you can start improving at cross and F2L:
-You need to work on planning out your whole cross in inspection. If it's difficult at first, try planning just 3 pieces and once you've done that you can try all 4. If you can plan your cross in inspection you should be able to do it with your eyes closed - which is a practice drill I did when I was learning this.
-For F2L, if you haven't already, learn intuitive F2L; many cubing yt channels have videos on this. Go through a lot of solves slowly trying to be as efficient as possible with pairing up your pieces, and if you notice any inefficiencies try to work out what you could do better.
You should, although you don't want to learn too many algs, if you haven't already, make a start on full PLL too.
2. Sub-5 2x2 w/ ortega
-Make sure you can do all of your OLLs and PBLs fast, if there are some outliers consider choosing another alg or drilling them.
-Ortega is a 3-look method, but for sub-5 you really want to try to turn it into a 2-look method. In inspection, as well as your face, track the U-layer stickers of 3 U-layer pieces to predict what OLL case you will get. With practice you should be able to do layer + OLL without pausing. From there all you need to do is recognise and execute PBL.
Hope this helps somewhat, there are obviously more things you can do but this is ju
