solve: B D L2 U L U' L2 F L F2 U F R' F' R F R2 B (18)
nice start on normal scramble: B D
pre-moves (D' B') on inverse scramble 2x2x2 block: B' R2 (2+2)
pre-moves (R2 B) on normal scramble:
2x2x2 block + pairs: B D (2+2)
extra pre-move (F) (2+3)
at this point F L would be the obvious thing to do for a 7-move 2x2x3 block (like Tomoaki suggested), but then the FL-edge would be flipped in an uncomfortable way so I did:
flip FL-edge: L2 U L U' L2 (7+3)
surprising F2L: F L F U F (12+3)
common LL-alg: F' U' F U F R' F' R, 5 moves cancel! (15+3)
undo pre-move: F R2 B (18)
finding good pre-moves are crucial (unless you name is Erik Akkersdijk (-; )
PB and 1 move above optimal solution!
BTW: optimal: L F2 U2 R' U' R' B2 U F B U' B' D' R2 D2 L2 F2 (17)
