Can you use pseudo blocks with NISS? I'd bet I'm probably just not understanding how it works, but I can't get it to work.

L B2 R B2 L2 U2 B2 F2 U2 R' D' R' B' U R' B' D2 F2 D F

(U' R F B2 R' U') // EO and 2x2
B' D B D' F2 // pseudo 3x3x2 (yes I know this breaks EO)

As I understand it, I should do the first line inverse, F2, scramble then second line. Right? It doesn't seem to work.

L B2 R B2 L2 U2 B2 F2 U2 R' D' R' B' U R' B' D2 F2 D F

As I understand it, I should do the first line inverse, F2, scramble then second line. Right? It doesn't seem to work.

So the 2x2x3 solution would be this

(U' R F B2 R' U') // EO and 2x2
B' D B D' F2 (F2) // 2x2x3

If you want to have a 223 on normal, do the inverse of the whole bracketed sequence, scramble, whole non-bracketed.
As in F2 U R B2 F' R' U (scramble) B' D B D' F2

Thanks Tom! If I were to do more on inverse, would I put the F2 after all of that? So then it'd be

(U' R F B2 R' U') // EO and 2x2
B' D B D' F2 // 2x2x3
(rest of the solve on inverse with the F2 here)

and if I did some on inverse, then some more on normal it'd be

(U' R F B2 R' U') // EO and 2x2
B' D B D' F2 // 2x2x3
(stuff)
stuff that finishes the solve (F2)

Right?

Not quite. When you make a pseudo-something, just leave the fixing-move where it is.

(U' R F B2 R' U') // EO and 2x2
B' D B D' F2 (F2)// 2x2x3
(stuff)
stuff that finishes the solve

Which would end up as B' D B D' F2 stuff that finishes the solve (inverse of stuff) (F2) (U R B2 F' R' U)

This is for the current weekly forum comp. First ever (successful) attempt with insertions, though admittedly the skeleton was harder to find than the insertions on this solve. I also used Jay/Brest's method to find insertions in this solve.

Here's my third solution from PBQ Berkeley Round 1 (the only one interesting enough to post):

Scramble: R’ U’ F L’ U2 B2 D2 R’ B2 R U2 L2 R2 B R D’ F2 U2 R B2 D R2 B’ R’ U’ F

Spoiler

L' F' L // EO
(U' R2 B U') // 2x2x2
(B' D2) // 2x2x3 + 2x2x1
(B2) // F2L -1 missing a corner
(D' F D' F' D2) // 4C

Skeleton: L' F' L D2 F D F' @ D B2 D2 B U B' R2 U

@ = F, D B2 D' (Changes the 4C into a better kind of 4C, cancels 8)

New Skeleton: L' F' L D2 F # D2 B2 D' F' D' B U B' R2 U

# = F' D' B D F D' ^ B' D
^ = D' F2 D B' D' F2 D B

I'm extremely proud of this solve, due to the insertions. If I hadn't inserted the comm that cancels 8, IF gives optimal (with pure insertions) as 27!

R2 U F' // pseudo222 (3/3)
inv: F U2 R2 U R' // pseudo223 (5/8)
U R2 B' R' // eo (4/12)
B U B2 U2 B2 U' B' // f2l (7/19)

I didn't know this ZBLL, and it's not a short one anyway. Instead of doing a 10-move alg to force L3C, I just started looking for insertions.

Skeleton: R2 U F' U R2 B' R' @ B U B2 U2 B2 U' B' R U' R2 U2 F'

Inserting U B U' B' at @ to solve the edge 3-cycle cancels five moves, essentially being a (−1)-move-long insertion. (!!) This leaves four corners (3-cycle + twist), which I did in the usual way.

$ R2 U F' U R2 B' # R' U B' U2 B2 U' B' R U' R2 U2 F'
# = [D, R' U2 R]
$ = [D' L' D, R2]

Five moves cancel, leading to a final length of 29 moves:
D' L' D R2 D' L D U F' U R2 B' D R' U2 R D' R' U' B' U2 B2 U' B' R U' R2 U2 F'

Making blocks, destroying blocks, restoring blocks. Skeleton isn't particularly good, but whatever.

On another note, I hope I get at least one sub-30 at SG Open tomorrow. (E: DNF / 36 / 35, welp. The DNF could've been a 34 if I didn't go full retard on copying the skeleton. Still NR2 for mean, I think, but the gap from guysensei1's NR is pretty wide now. And congrats!)
