U' F' R // square

U (F') // 2 more squares

L' F U L' R' F' R F B R2 U2 -2X2X3
Normal pseudo F2L solution (F L F L) leads to parity, then I decided to sacrifice one 1x1x2 block to build Green-Red-White 2x2x1:
U L' U' L' F' L2 F2 L F L2 - L3C
L2 F' R' F L2 F' R F -SOLVED

D U2 R' B (L' U') // 222
(U' R' U) // two-222
(R D R' D L D2 L' D' F' D F D2) //L3C

Skeleton: D U2 R' B D2 F' D' F D L D2 L' ^ D' R D' R' U' R U2 L

^= L D L' U2 L D' L' U2

D' L' - protect Yellow-Blue edge, build Yellow-Red-Blue pair. I didn't want to break the ready-made pair to finish YRB 2x2x2
(F' U2 R' U' F') - X-Cross + pair. I found a few three movers to insert the Blue-Orange edge during this step to get an XX-Cross, but none gave a good continuation
U' B D B' U - Keyhole to solve BO edge, builds a square and an F2L pair
D F' R F R' D' - Sledgehammer to solve F2L pair, leaves 2C2E
Skeletton:
D' L' U' B D B' U D * F' R F ^ R' D' F U R U2 F (18)

*: U' B U' L2 D F' D' L2 U2 B' (10-2)

Gotta admit, I had to have a look at Sebastiano Tronto's tutorial to know more about 2C2E insertions, and I got lucky to get one of the algs he shows.
I also found this insertion at ^ : F2 R F R' F2 L F' R F L' R' (10-2)
It is the inverse of a shifted version of the alg : L' U' L U2 R' L' U L U' R U2

F' U2 R' B // EO (4/4)

Bad insertions because I spent way too much time trying to rNISS an 11 to 4e4c. Couldn't try many starts :/

F' R' U2 B' // EO (4/4)
D' U' R' D // square + pair + set some edges (4/8)
B2 R L2 D2 R L2 D' L' // F2L-1 (8/16)

U^R B D' L (EO)

Block-building from inverse:
(L' F L R B')
(D' L' U' D' B U B2)
(L U' L U L' U L U2 L2 U' L2 U' L2 U2)
(U' L2 U R U' L2 U R')

All what I found in 30 minutes before contest was closed.

U B' F' R D' R F U2 R' - xx-cross
D F2 D' - 3rd pair
F U' F U F2 U' F2 U - 4th pair
R U2 L' U' L U' R' - OLL
L2 U2 L' D' L U2 L' D L' F2 - PLL

2x2x2 + white cross piece: F U L' R U2
2x2x3: F' D' B D B'
Then go to reverse scramble.
Pseudo f2l: F L D L' D2 R F' R' D2 F2 D
OLL: U' F' R' F R U F2
PLL: R2 F R F R' F' R' F' R' F R'
AUF: D
Then rewrite all from reverse scr to the end of solve and it is done.
