Also, I have particular issues when the pair is CW, WC, IS or SI. I “should” be doing the first alg twice, but that never works for me... what am I missing?

It should work, here's an example scramble/solution with only W and C as targets:

Scramble: (U2 M')4
Solution:
M U2 M U2 // W
M U2 M U2 // C
View on alg.cubing.net

And here it is on a full scramble that contains the letter pair WC:

Scramble: U2 F2 L U2 R2 F2 R2 F2 L D2 F D2 F' D' B F2 U' L D2
Edge letter pairs: PE AR WC XN LM OA
Corner letter pairs: CH GK MD OI
Corner twists: B counterclockwise

Solution:
// Edges
[B' R2 B: M2] // P
[B L' B': M2] // E
M2 // A
[U' L U: M2] // R
M U2 M U2 // W
M U2 M U2 // C
[U' L2 U: M2] // X
[R B' R' B: M2] // N
[U' L' U: M2] // L
[B' R B: M2] // M
[B' R' B: M2] // O

I guess I still get confused about the buffer piece. Maybe I get confused because I’m thinking too much about ... in your edge memo, the first A is actuall U. That’s just a cycle break, right? My brain has figured out to ignore that while doing memo for op. Just need to rewrite my brain to ignore K or U (speffz) instead of B or M.

Correct.

I can sort of relate. I've never switched BLD methods, but I did switch orientation, and at first it's a pain getting used to recognize cycle breaks.

Below google sheet is what I summarized for M2 & Advanced M2.
Not completed but figured I wouldn't work on much any more. At least you can see the 2nd sheet - setup / unsetp cheat sheet for basic M2.

Missed 5BLD both by l slice and couple of D2 off.
Time was 29min (both attempts)

1st one, T center execution was off in the middle, tried to fix it but looks like missed l slice in the process.

2nd attempt, forgot the last two T center pairs, moved on to Wing and midges and recalled those two pairs, executed but again, off by one l and one D2.

Waisted wonderful supports from my fellow Oldies (Jeremy and John) :-(

@openseas Sad to hear this. I hope you'll succesfull next time.

 

[pglewis]

Bummer @openseas, @SpartanSailor on your goals. Last time out I was 0-fer on 3bld and a 40 avg for 3x3, so I feel your pain.

 

[Mike Hughey]

Nothing's more painful in cubing than striking out on BLD in competition, but I can speak from experience - it makes the next success that much sweeter when it finally arrives!

I currently have a streak of 7 5BLD DNFs in competition, which is just horrific for me. I hope I can get to another competition with 5BLD soon, but it's looking like that may be a while. So I feel your pain too.

Thanks, all.

Just realized what was wrong for the 2nd attempt. I should have finished T center before wing / wing parity! It ruins center. When I memorized, I memo'd wing as even pair but during exec, I realized that added one more letter (duplicated), so, did parity to close. That rotated some centers!

11 attempts of 5bld in last 3 years. No success so far. I mean official. In home my success rate is around 10% now.

You did well and it was nice to be in your fan club today.

Same here, 11th DNF, no official success yet.

Finally... I’ve “figured out” M2 edges... sort of. If I use my notes, I can get it to work out. I still have to learn the various special cases to make them smooth and the set-ups to skip FU and BD locations when pairing with a non-M slice edge. (I like this trick, btw...)

Still have a follow up question: the case or situation when I need to swap FU/UF with BD/DB. Or just needing to flip the FU/UF edge...

I just can’t figure that bit out. I don’t like the idea of trying to learn a new alg for each piece like this... in defense of OP edges... there’s no special weird cases and I can just blaze along without all the extra mental gymnastics.

FU / UF - BD/DB has nothing special about it. Just remember to do the BD/DB piece as the second piece... not the first. (Swap the targets.)

Edge flip algs, there's 1001 on the net. I'm starting to learn one. (M' U M' U M') U2 (M U M U M) U2 flips UF and BF.

A F2 setup and F2 back would make it work for M2.

I wouldn't worry about the advanced techniques for swaps there until you have the basic M2 mechanics comfortable. Since you're already developed with the basics of blindsolves I'd just spam edge solves for a couple days via M2, sighted if you need to as often as needed. A few days and you'll be well on your way.

Day 2 in the war on sup-25: now it's just getting silly. Dropped the Ao50 a couple more tenths to 25.30, but the first Ao25 was 23.90 :rolleyes:. Literally bombed the whole thing with 5 straight sup 30s on the last 5 solves. I'm having a good 3x3 spell despite that annoyance, all averages have moved this weekend and single is easily beatable with one really good one plus a skip.

The first edge flip I learned was for this case and is still my favourite
M' U' M' U' M' U' M' U2 M' U' M' U' M' U' M'
Switch U' for U if you prefer

IMHO it's best to master basic M2 before moving on to special cases and advanced tricks. Apart from learning the algs and coping with odd/even targets, there's nothing more complex to M2 over OP. You can do all swaps and flips by shooting to appropriate targets, and that will continue to be useful knowledge in future even after learning more advanced tricks.

@pglewis i like that you have “waged war” on your time goal! That’s motivation for sure!

I was trying to avoid learning the longer alg for FU and BD targets, but drilling those a little will be easier in the short term and pay off in the long run. That being the case, i was pleased to do a full blind solve using M2 without my notes. Happened to be an even number of targets, but still managed to get the UF tarted as second in a pair and so applied it’s “partner” alg for DB.

Any way you slice it (pun intended), I’m having fun learning new stuff. My next comp with blind is the Maryland 2018 on June 30-July 1. I think I’ll use M2 for that comp and just see what happens. I mean... I have the concept already. I “should” be able to dial in the special case algs by then.

Both algs are very usefull and in fact are comms with M2 added.
