and for the case (R U' R') U' (R U R') U2 (R U' R')

It's interesting to note that if you do an x rotation this is the same as your first example case. I think it's of dubious utility, but you could bring them out undisturbed with a hedge-slammer (F R' F' R, probably in muscle memory from flipping edges on 4x4) and be setup for the first example.

From the department of sledgehammer abuse is double-sledge to solve F2L 29. I'm actually liking this one in speedsolves, even if they're not in the correct slot a single sledge still joins the pair. I'm comfortable with it from either side, so as soon as I spot the case it's just a matter of sledging once or twice.

if nothing else it proves the value of reviewing F2L solutions periodically

Feliks has uploaded an F2L cheat sheet in the intermediate section of cubeskills btw. Probably worth a look.

Good reminders, and bookmarked resource. I have a few remaining that still give me fits, I should stop what I'm doing when that happens and re-examine those cases.

Where I continue to really struggle is finding the correct orientation to split a pair or bring them over the top when I'm down to the last slot, or even last two sometimes. I just don't see it and register it well. I've yet to find a fast, non-thinking way to get there and then things like y3 happen because my hands are bored while I consult the thinking bits. Lots of other aspects are becoming more automatic but this one doesn't seem to want to budge.

Always know where the empty slot is and always turn away from the empty slot. Not sure what else would help here. But I know the problem, sometimes I do lots of unnecessary AUFing as well.

A few weeks ago I realized something new about F2L. If the corner is in the slot wrongly oriented, then it doesn't matter where the white is pointing, I should always bring the edge piece in the top layer to the position where the edge color matches the center, then it's in the correct position to turn away from the slot. Maybe this is standard knowledge for everyone else, but for me it was quite a revelation when I realized it. Before that I always had to study the corner in the slot carefully to know where to place my edge piece.

31.766 OH Mo100, it seems I'll be able to reach sub-30, but I'm not sure about my sub-25 goal, I'll need algs and a better cube for that... for those that have used a Weilong (not the GTS) and a Valk3 for OH, how much better is it?

 

[Fyzzna]

Did my first ao50 today: 48.59. Also got a single PB of 33.89 and an ao5 PB of 42.18

 

[Shaky Hands]

and then things like y3 happen

Hope you manage to break that habbit!

I noticed you got your best times in the Race thread this week. Well done.

I have a mini-Weilong, I could never setup right.... I never liked it. Valk 3, especially with magnets... it has helped my times quite a bit.

 

[muchacho]

The last OH single that I uploaded to Youtube was 28 seconds or so, so I've uploaded a 21.8 one... that should have been sub-20 if I'd paid attention during LSE.

Roux OH FTW! Roux solves always seem so elegant to me, it's a joy to watch.

I used a mini Weilong v2 for OH for quite awhile and recently switched to the Valk. My times have only slightly improved due to practice but I do think it feels better. Finish learning those CMLLs.

I was disappointed to find that there is no space for magnets in the mini Weilong.

A concrete example of one that sometimes gives me fits is F2L 15 (and the mirror, 16; this applies to both since I lump them together as "the same case" mentally but I'll use 15 as the example for the specifics).

My first instinct for the general case is to flip the corner's orientation by going over the top of the edge. To do the quickest flip and insert I can execute, I end up with a rotation then a rotation back.

The above approach is more palatable to me when the edge is misoriented: split over the top, then rotate to orient for the insert. Edge was misoriented and I did exactly one 90 degree rotation, perfectly acceptable. But when I see the edge is already oriented I'd really, really like to be able to invoke a general "don't rotate" rule and this violates it. The first intuitive stab at addressing that problem is 100% equivalent: flip the corner orientation with F layer turns rather than a rotation and L layer turns. Move efficient and rotationless but a little awkward and unflowing for me. Might just be a matter of practice.

An R turn is slot-safe with the slot's orientation so a different approach would be to flip the corner's orientation that way, bringing the bottom layer sticker to the top and resulting in a rotationless, regripless, R/U 2-gen approach. Less move efficient but maybe trigger/finger-trick loaded enough to compensate.

After deconstructing, the one I think I'm sold on isn't as obvious. With the pair opposite the slot, a sledgehammer will flip the corner's orientation without touching the edge, leaving a quick AUF and insert. Rotationless and I always welcome new members to the Department of Sledgehammer Abuse. Remains to be seen if this works as well while solving in anger as it does in theory. I do still think it's worth considering different ways of handling this case based on the edge orientation at the time, regardless.

It does, I use this and several other sledgehammer based solutions. The only drawback is that they aren't so nice at the back. Sometimes I'll use different solutions when mirroring thise cases to back slots.

Lubed and cleaned my clock really good today, and then got a PB 8.99 ao12. I'm gonna get greedy and change my comp goal to sub-10 (then maybe I can actually get sub-11)

Spoiler: times and scrambles

Average of 12: 8.99

For those who like easy 3x3 scrambles, I had this 2 move x-cross
L2 F2 U2 F' R2 U L U L F' D2 B' L2 F U2 F D2 F' R2
I only got a 16.71, which is really good for me but not for that scramble, then got 9.75 after a few more tries.

sub 9 sq1 single! Too bad is was lucky ...
8.891: (-5, 0) / (0, 3) / (6, 0) / (2, -4) / (4, -5) / (5, -1) / (0, -5) / (-3, -3) / (-4, -3) / (-4, 0) / (4, 0)
-4,0/-4,4/-1,0/-3,-3/ | CS (4-2/pair), not the most common way to do this shape, but it only leaves me with F/F as PBL
2,-3/-1,2/-2,-2/3,0/ : pure J/J corner swap
/3,-3/-1,-1/-2,4/-1,6 : op/op EP no flip, for the end
12 twists

More common ways to do the CS:
-2,2/-2,0/-1,-2/-3,-3/ : this leads to parity
-4,0/4,0/1,0/-3,-3/ : no parity this way
possible solution after:
3,-4/-2,-2/ : OBL
3,-3/0,3/-3,-3/3,0 : CP (JJ)
/3,0/-1,-1/-2,1/5,0 : EP (adj/adj)
13 twists

or
3,2/-2,-2/ : for OBL and we have once again F/F as PBL

Another bad, no sq-1 next comp

 

[muchacho]

When is your next comp?

 

[Lid]

When is your next comp?

Next weekend, it "just" has 2-7,OH,skewb,pyra,fmc & some "crap" bld

 

[muchacho]

Good luck! For me 3x3 and OH would be enough, I've forgotten most of the few others I learned to solve.

hi everybody, long time without posting here.

I see lot of us registered to worlds, and I've been told some of us are also registered as staff, Do you guys have everything booked? I'm planning to get plane tickets this week and the hotel soon enough, can't wait to meet some of you!

I have had a very busy year so far with very little cubing, but I plan get back to it from easter onwards to try to have a good comp on mid May and to get ready for worlds.

Last weekend I had a comp in which I could just be there for an hour (I only did 2x and 3x first round) and did my first comp without PBs. I had memory lapses remembering PBLs in 2x2 and had two +2 and some judging problems on 3x3 but at least my comp count is now 20, how are you guys?

Hotel and train booked. Only doing pyraminx and 3BLD so better get a PB. Doubt I'll be at any other comp before this.

Ao5 PB: 15.321 ...done in the WC, maybe a bit of pressure is not bad.
