**Scramble:** B2 D2 L F2 R D2 L B2 R2 F D R’ B’ L R D’ F2 L’ D2

**Solution:** R’ B R2 B2 L B’ R2 L2 F R2 B’ L’ U B2 U’ L’ F’ L2 F’ L’ U L2 U’ L F2 L D2 R2 (28 HTM)

**Explanation** (with my NISS notation, move in brackets are done on inverse scramble):

R’ B *//2x2x1 (2/2)*

(R2 D2) *//Expand to 3x2x1 (2/4)*

(U B2 U’ L B)* //Another (pseudo) 3x2x1 (5/9)*

R2 B2 L *//Roux Blocks (3/12)*

(R2 F’ L2 R2 B) *//All but 3 edges and 3 corners (5/17)*

*Final Skeleton (for normal scramble) + insertion:*

R’ B R2 B2 L B’ R2 L2 F R2 B’ L’ U B2 U’ * D2 R2

* L’ F’ L2 F’ L’ U L2 U’ L F2 L *//3 corners and 3 edges (11/28)*

**Comment:**

The insertion is a setup + 9 moves pair 3-cycle: [L': [F2: [F L2 F’, Rw’]].

I have explored some other starts, but the only one (except for the one above) that gave some nice continuation was this:

D R’ D2 R2* //2x2x1 (4/4)*

D L D *//2x2x2 (3/7)*

B U’ B’ *//2x2x3 (3/10)*

L F’ L’ *//More blocks (3/13)*

F’ U2 F2 U’* //Pseudo F2L-1 (4/17)*

F U2 R U R2 F2 R F2 *//All but 3 corners (8/25)*

I’ve kept this as a backup partial solution, planning to quickly look for a 3 corner insertion in case I was left with only 5 minutes or so.

When I have finally found that “All but 3 corners and 3 edges” skeleton I had only 10 minutes to find insertions. I knew it was probably going to be better than the backup skeleton, but maybe 10 minutes weren’t enough. In a competition I would have probably looked for a 3 corners insertion in the backup solution (I don’t like risking a DNF, especially now that FMC is a Mo3 event) and be satisfied with a 30 moves solution (optimal insertion found by IF, but for a single corners 3-cycle it’s pretty easy to find optimal insertions). But, since it was only practice, I decided to go for the (I thought) double insertion on the other skeleton. Both corner and edges were awfully placed during the whole skeleton, the best I could find was 7+8 for a 32 moves total, until right before the end, when I saw that the edges and corners could be solved with a pairs commutator after a setup move.

In case you don’t know, pairs commutators work exactly like corners commutators, but at some point you use a wide turn. A few examples can be found on Ryan Heise’s website, at this page (Strategy #1: pair 3-cycles).

BTW, if you set the “other” option on IF, it finds an even better insertion (while using only the “corners 3-cycle” and “edges 3-cycle” options it gives 30 HTM as the best solution).
