You could totally pass this off as a ZZ solve and no one would know…

Now that you say that and I ran through it again it could totally be a ZZ solve

I've finally registered for Manchester 2018 and rather foolishly put down for 5BLD. What's the best resource for learning it please?

Good man

I learned from Corey Sakowski's tutorial. The only new thing is U2 for T centres, plus a minor complication on midge parity. The rest you know from 4BLD.

I've just been chatting to a couple of people on the BLD Support Facebook group and it's easier than I thought. I like the suggestion of using M2 for plus centres but I'm not sure about the parity fix for it.

IMHO it's easier to use U2 as it's so similar to what you'll be doing for the X centres. For T centres U2 is even easier as there are no tricky algs for the D face targets.

How would you do the U face targets? Do you just do a l or r setup?

I use the same trick as M2. Something like U2 setup U setup' U. For X centres that doesn't work if adjacent to a D target so I use a comm with l slice interchange in that case.

Thanks. I'll add that to my notes.

@newtonbase / if you solve all centers, for midges parity, normal 3BLD M2 parity alg takes care of the thing. Agreed with @mark49152 , T center is easier than x center. For th adjacemt x center, I float the buffer (simply U or U') instead of comm.


Btw, 2018 first comp. finally, first sub 2 BLD. 1st round 1:47, final 1:39. Both of them came in the last attempt: went safer but success.

 

[mark49152]

Thinking about M2 for T centres, how do you handle the other 6 targets in the M slice? Do the usual M2 algs work?

Yes, 3BLD M2 alg works. No center treatment needed.

Congrats. Good time.

I don't have a 5x5 with me but I can't get my head around that. You're saying that to solve the UF centre I would do U2 M' U2 M'...? Regardless of what that does to the T centres, doesn't it mess with the midges?

Edit: Maybe it should be u2 M' u2 M' with slices. I should find a 5x5 and try it. But how would you solve the FD centre since that has no equivalent in M2? Anyway, it seems inevitably more complex than U2 since you have to deal with 6 special targets on the M slice rather than 2 on the U layer.

How do you deal with D layer T centres? I've messed up my wings trying them?

With U2? If your buffer is UR, do y and use M u2 M' to setup X to the helper position UL.

I did find a 5x5 and cannot figure out how to solve the Uf and Db targets with M2 algs. I didn't even try Fd. Personally I can't see how M2 could be recommended as easier than U2 for T centres.

I was over complicating it. Thanks. I've yet to decide on a buffer.

@mark49152 Just to clear up, I was talking about M2 parity algorithm not M2 alg in general.
@newtonbase below tables, summarized algs needed for 4 & 5 BLD when you use U2, r2, m2, OP method.
My buffers are, Ulb, Uls, DF, UBL

For D layer, I use both x & t center same alg except d2 for X-center, e2 for T-center.

For OP, you only need 1, just listed 4 specific, 5 specific, one that can be used for both 4 & 5.

Gents...

Incidentally, do we have any women in this old “guys” group?

Anyway... when a comp says “best of 3 with 20:00 limit” does that mean 20 mins total time to make three attempts?

Yes, all 3 events are combined time limit. So, even with DNF, judges need to write the time to calculate the accumulated times.
