------------------------------
my first moves: quick start: B U F' L F'
to fix pseudoblock at the right add premoves (R2 D)
continue obvious start: 2 blocks: B F' U (3+2)
I investgated this start for several minutes, parked it for later, and investigated an alternative start with these same promising pre-moves (R2 D):
2x2x2: B U (2+2)
save pair before creating next block: F2 (3+2)
block and extra pair: D' F L2 D (7+2)
another block and extra pair: L2 D L' (10+2)
finish F2L and LL-skip: R F R' D' F' (15+2)
undo pre-moves (R2 D) (17)
Very lucky solve, 20min!
PB and optimal solution!
