2nd scramble from the current German forum competition:

R' L2 U' B' D2 F L B' D R2 U' F2 U L2 F2 L2 F2 U2 L2

My solution:

With Premove R2 on Inverse:

2x2x2+Blocks: U' D F'
Way more Blocks: F' D F D' B2 D L
3C3E: B D'

Skeleton: U' D F2 D F D' B2 D * L B D R2

* = R' F2 R B2 R' # F2 R B2
# = R B2 R' L U2 L'

Inverse Solution: U' D F2 D F D' B2 D R' F2 L U2 L' F2 R B2 L B D R2

Solution: R2 D' B' L' B2 R' F2 L U2 L' F2 R D' B2 D F' D' F2 D' U

20 moves. :)

wow... sweet! congrats.

I'm a bit interested in the domestic forum competition.
How often is the competition held? once a week?
How many scrambles are provided?
How many competitors participate in it usually?

There are 3 new scrambles each week. The main format is mean of 3, although there are single rankings with and without limits. Usually there a between 3 and 6 participants. Here is the thread on the german forum: http://www.speedcubers.de/showthread.php?tid=4572&page=163
 
Thanks. :)

It is held once a week and 3 scrambles are provided. We rank both by Mean of 3 and Best of 3. The number of participants is usually between 3 and 8 people I'd say.

Edit: Ninja'd!

Nice!
My attempt before opening your spoiler:

on inverse with premoves R2 L'
D U' L' F2 D' F L B2 L2 - F2L minus one corner in 11 moves
Doesn't look too bad but could not find a good finish...

My fail solution for the weekly comp...

Scramble: F D' F U F2 R' F' D B' L2 B2 L' F2 L D2 L F2 L B2 L'

R' B D R L . F' D' L2 D2 - 2x2x3 - 9
R2 U' R' U - leaves 5 corners and 2 edges - 13
at . insert D B' D' F' D B D' F to cancel 3 moves - leaves 2C2E - 18
I did not spot a good insertion for this 2C2E - fail

Can anyone find a good insertion?

Very promising start!
I didn't find a good insertion too, probably there isn't any.
But if you continue differently after move 12 or 13 there are at least 2 other options to get an easy sub 30 (-;

Awesome 2x2x3!

Some continuations/finishes I found within 10-15 minutes:

L3C: U R2 U2 R2 U R F' U2 F U F' U F U
30 moves...

F2L: U' L' U R2 U' R' L
ZBLL: L2 U' L U L U' L U D' L U' L' U2 D

Tripod: U' L' U R U' L
L3C: U L' U2 R U R' U2 L

gives 28 moves.

your continuation: R2 U' R' U'
F2L: B U' B' U
ZBLL: D' B2 D' F' U R2 U' F D2 B'

27 moves.

L3C: R2 U' R U' R U' R' U2 * R U' R U

* = U2 R' D' R U2 R' D R gives 25 moves.

I did not really try insertion your 2E4C (while I surely would try that on my own attempt), but I think first looking for a 2C2E insertion gives you more opportunities.
 
My first FMC attempt! From the weekly competition:
F D' F U F2 R' F' D B' L2 B2 L' F2 L D2 L F2 L B2 L'

x2 // Inspection (0/0)
L D2 R' F' B' D L' D // EOLine (8/8) I know my EOLines suck. But this one had quite a lot of incorrectly oriented edges, so I'm very happy with only 8 moves.
U2 R U L2 // F2L-1 (4/12) I got lucky with an easy start to the F2L here.
U R U' R' U R' U' L' U L // CP223 (10/22) CP isn't usually good when the pair is connected, but this wasn't too bad. Only 3 extra moves.
R2 U R U2 R' U R U R // F2L (9/31) Yay, more lucky F2L!
U2 R U2 R' U' R U R' U' R U R' U' R U' R' U' // 2GLL (17/48) A very bad case for movecount, but as I actually knew the alg for it was better than most other LLs I could find where I'd have to do two algs.
Yea... 48 moves is quite a lot. You'd think there's a lot of time in FMC but there really isn't.

Nice beginning! After that (first 9 moves) I would have done something like this:
L' F D F' L (found using some premoves)
Leaving 3 corners and 3 edges.
Insertion finder says 25 moves is optimal for this skeleton.
but nice solution anyway.

P.S.: In case you didn't know, there is a problem with the website, so if you want to submit a solution you have to put a \ before each ' in the comment section. For example your comment should look like:
2x2 Block & F2l : LB\' # U2 B2 FD\'FU\'R //
F2L minus 1 slot : BDB\'D\'R\'D\'R //
All but 3 corners : DBD\'B\'D BDB\' //

Insert at # =B\' D B U2 B\' D\'B U2
I don't know if there is the same problem with some other special characters.

Can you please explain your LL? Was that skip forced or lucky?
 
Yes of course, for LL I wanted to orient the edges first, and I saw with L2, I can have two pairs (of course 3 pairs after L2 F' L' F). after EO, I find the OLL skip (Actually not skip, It was for Winter Variation). But the PLL was skipped, This skips usually happens if you have pairs at last layers. I usually dont solve like this, because it is hard to find sub-30 with OLL and PLL, but when you have pairs at last layer, it is useful to spend your time for finding OLL SKIP or EPLL most of the time.
