Hi Erik,
thx for your solution, I will have a look for a possible 2C2E insertion this evening to see if it is possible to get rid of those 3 moves "to optimal".
This is actually part of my 1 h solution for fmc.mustcube 365 (where I will submit my 32 HTM sol).
I will try a different start for the classic as I don't think "team" solves are allowed

my solution for the weekly competition in the german forum. it's 24 moves so i thought it would be interesting to share:
scramble: D' L2 D L2 F2 U' L2 R2 U B2 L' U B2 U2 R B' U L U2 L' R'
2x2x1: U2 R2 U' B (preparing the 2x2x2)
2x2x3: F2 (in order to solve the yellow-red-green F2L pair) L2 D' R
some more blockbuilding: U2 F U F' U * L' F U' F' (leaving 3 corners)
1-move cancellation (this was the best one i could find):
* D' R2 D L D' R2 D L'
=> U2 R2 U' B F2 L2 D' R U2 F U F' U D' R2 D L D' R2 D L2 F U' F' (24 moves, found in ~30 minutes)

Well done, but there's a better insertion:
some more blockbuilding: U2 F U F' U L' (L' F R F' L F R' F') F U' F' (leaving 3 corners)
results in 22 moves.

And this is why you should know your BAB'A'
And offcourse props to Whauk for finding such a nice 24 mover.

Irontwig,
would you mind posting your 11 move F2L-1 for #365?
I would like to compare to my 11 mover which I also found hard to finish.

My first attempt at FMC. I got stuck at the end, and didn't finish. I'm going to try and do it over to get a different result/ finish.
Any tips are helpful.

Straigtforward fixing of edges gives 20 HTM for L5C, could still be 30-ish. Did you run out of time?
Nice to see you here
Some hints:
Write down your solution in steps, this makes it easier to follow what you have been doing / what the thought process is.
Write down your solution without rotations. With rotations you may miss some cancellations.
Definitely try several options at each step of your solve: expanding blocks in different directions - various ways of inserting CE-pairs - inserting moves between steps - using mirrors, etc, etc.
Brows through this thread, AVG fewest moves tips and tricks and the weekly comp solutions to see what others are doing.
AND: forget about the 1 h time limit for now, just keep working that scramble.

Quick attempt with your 2x2x2 block:
F' R2 U R2 U2 F' L' B D' B' D' R' L' F L R' U2 R F' D2 F R' U2 R F' D' R (27)
F' R2 U R2 U2 [2x2x2]
F' L' B D' B' [2x2x3]
D' R' L' F L F' [Leaving two corners]
F R' U2 R F' D2 F R' U2 R F' D2 [Two corner twist]
D R [Finish]
Ralph: Yes, running out of time trying to find something for a 25-27ish solution.

Might as well post this from the example game thread:
Scramble:B' U' D2 F L2 R' U D' L R B L2 D' F U D F2 B U D R' F2 U2 F' R2

U F U' R' L D' R' [2x2x3+2 pairs with one inserted move turned into pseudo tripod]
F [Pseudo F2L]
F U F' U F U2 F' U [LL]
F' L2 B' [Undo pseudoness]
Ties my pb, though I'm pretty sure 25 move scrambles generate (somewhat) easier scrambles than random state used by Cube Explorer and WCA or Fredlund's 30 move scrambles.

14htm with (hopefully) two 8 move commutators is 30htm minus cancellations.

Hi cubers, who do not care about speed anymore!
I am glad I found my old password to this forum. Thank you for welcoming me back. I was hesitating a while for two reasons. First, I thought I've seen all possible scrambled cubes already. But it turns out I don't remember all of them. Second, I may not be the best anymore after Guus improved a lot and big new names like Tomoaki, Joan-Carles, or Bruce, who learned all my tricks and more rule the FMC competitions. I want to mention FMC #356 where Tomoaki reminded me my old years with his insertion of (D F2 U' L U B') D (B U' L' U F2 D') leading to impressive 20-move solution. Great job, Tomoaki!
This week you'll see a nice linear solve from me (#367).

Nice to see you around. I would really like to see what you can do the with the current scramble for the weekly forum competition, as I failed to find anything good and thus DNF'd.
This is a tough one. I tried what guys call NISS (Normal-Inverse-Scramble-Switch).
After U D R' switch to inverse. Denoting the scrambling sequence s, you do R D' U' s' on a solved cube before continuing.
D' R2 suggesting a premove [D']to get 2x2x2 block, F L' F D' (U)L' D. The move (U) I inserted to ge a better outcome. We have a 2x2x3 block and two corner-edge pairs. U' L' having f2l without one corner in total of 15 moves and a nice last layer.
You can switch from inverse to normal scramble now:
(L U D' L U' D F' L F' R2 D) s (U D R'), postpone [D] till the end and solve edges R' U' F R' F' R U R U' D leaving corner 3-cycle. Before finding a good insertion, we better rearrange what we've done so far:
s (U D R')(R' *U' F R' F' R U R U' D)(L U D' L U' D F' L F' R2 D) Now, I place numbered stickers on the 3 corner cubies and watch how they move when undoing move by move, i.e. performing slowly D' R2 F L' F D'... and found an insertion at * (D2 F' U' F D2 F' U F). This was one of the worst cases of an insertion. So many slice turns! I wish I had an edge 3-cycle to look for instead. My final solution is U D R2 D2 F' U' F D2 F' U F U' F R' F' R U R U' D L U D' L U' D F' L F' R2 D (31). BTW, it contains no B move.
Switching between normal and inverse scramble requires some practice, otherwise one can waste a lot of time due mistakes in scrambling (which happened to me this time and took me more than an hour :-().
