Great news. A fantastic insertion can be done in the premove. Let's see:
Your solution : L' U' D L' B2 D2 L B' L2 D2 B' D B L @ B' U F'
At @ insert : (B U F' U' B2 U F U' B) : +9 moves but 6 moves cancelled in the end !
So, this is the 20-move solution for reverse(???) scramble :
L' D U' L' B2 D2 L B' L2 D2 B' D B L B U F' U' B2 U
Awesome ! Many thanks.
No need for a 9-mover. Inserting an 8-mover (B2 U F' U' B2 U F U') after the B' gives the same result.
