Random Blindfold Cubing Discussion

R D' y perm with F and F' removed D R'
M2/ OP
Average - 1:10 - 1:20
Incase my last target is BRU, I need to do R' F (y perm) F' R and then again R D' (y perm) D R' to fix parity. Anyway to finish both together?
Also when I have the corner UBR to be twisted clockwise or anti clockwise, it seems to be time consuming to twist the corner and then fix parity. Can both be done at the same time?

You can twist corners with sexy moves (for example, y' (R U R' U')*2 L' (U R U' R')*2 L in your case) or sune/antisune (y' L' U2 L U L' U L R U2 R' U' R U' R).

I don't think you get what I'm trying to say. I do know how to twist corners. I asked if there's a single alg to twist that particular corner and also fix parity.
 
I did a 3x3x3 blindfold solving demo for my friend Dr Wrayno's finite math class at Christopher Newport University tonight! The class had about 40 students in it, and I was pretty nervous because I wanted to make sure the solve was a success so that it wouldn't make Dr. Wrayno look bad for his class. The solve time was probably around 3 minutes or so, but I got it successfully and the class loved it! Their next topic is combinatorics, so I hope the demo and also learning about some related math to cubing will help turn some non-cubers into cubers!

Really love that feel! :) i remember Bernett telling me a lot of stories about his BLD solving in television channels and about now John Louis Sir helped you with memo at one point of time. I'll never get tired of listening to stories like these :) Great job.
 
Cube Explorer + some tweaks = an odd (but possibly useful?) 3BLD parity alg. Because of my UFL buffer I would normally do U2 M' U2 M then T-perm so I think I'll switch to this, it's nice to execute.

This morning on my drive to work the license plate in front of me was XBH-#### (I don't know what the numbers were).

For me that would be Malcolm X inspiring a group of bees in a BeeHive to protest human (and/or bee) rights!

Or it might be Beast from the X-men (XB) beating the **** out of Hitler.

...

but, I like to think it stands for eXtreme BH!!!

I'm picturing something that would probably be very similar to extreme ironing. If you've never heard of extreme ironing I strongly recommend you google it! It looks both strange, terrifying, awesome, and wonderful all at the same time!

That license plate totally made my morning! ;)
 
I don't know if many remember John Louis and his son, Bernett Orlando. They have been the oldest cubers from India. This was posted in our group today by John Louis, just felt like sharing here :)
Dear Cubers,
18th Dec is one of the most memorable days for me, Bernett and Ron. The same day almost a decade ago ( 8 years ago ) Ron met Bernett and me in Chennai, almost a month after 2005 world championship in Orlando USA.Unfortunately we were denied visa to visit USA for the world championship. Ron came all the way to TamilNadu when he visited Mumbai for his business to meet Bernett who was already solving a cube blindfolded. Back then hardly 10 cubers could solve the cube blindfolded - Chris Harwick, Tyson Mao, Lyon Lo, one Israel cuber etc . I guess the cube seed was sown in India on that day.
My sincere thanks are due to Ron for his nice gesture.
Keep cubing, make India proud !!
 
Isn't eXtreme BH move-optimal 5-cycles? :)

Ha! I like that! Sounds good to me :)

I remember when Ron took that trip and the pictures they posted afterward. Time flies when you're having fun, I guess! It was great to meet John Louis and Bernett in Budapest at Worlds in 2007, I learned a lot about memory and competing at a high level. Plus Bernett and I did team blind 4x4 BLD, which was so much fun! :D
 
Weird scramble:
R L F2 B L D' L2 U F B2 U2 D' F2 U2 L2 U R2 U

3 solved and 1 flipped corner, 2 cornercycles (one of the solved corners is my buffer)
1 solved and 1 flipped edge, 4 edgecycles
 
Easy center on this 4x4 scramble

Fw2 L' B L2 Fw' Uw L2 Fw2 Rw R2 U' L2 B2 U B' D' U L' Rw R' Uw B' Fw' F2 L D Uw2 U' Fw D2 Uw2 U L Fw D2 Uw R D Uw2 U2
 
I'm not sure what already exists in terms of parity alg lists (I'm only really considering 3BLD here btw). I recently looked at how I approach parity and decided that a certain set of double 2-cycles would be helpful, specifically (DF UB) / (DF BU) + (UBL XYZ), though for laziness I'm allowing 1-move setups for corners to have 18 cases instead of 42.

The plan is to do an edge 3-cyc for certain last edge targets to give me one of these cases. I've already posted somewhere the edge double 2-cycles I use for parity because it's a fun idea, now I plan to use a combination of the two, I can give more details if anyone wants.

Pretty sure some of these can be improved, since I only finished the list yesterday and tidied it a little today, I'll probably keep working on these a bit. I also realise that the bottom 2 cases are an L2 setup away from the 2 above them, but I might leave them in anyway. Thoughts/improvements welcome.

Didn't actually get any requests, but I'll dump this here anyway since someone might find it useful at some point. I actually miscalculated, and might only use half of these algs now that I've thought this through more ...

Edit: Btw, I've changed several of the c/e algs and they should be a lot better now.
