After the reduction to <R, Rw, U> and EO, if it takes a lot of moves to solve DF and DB, or if you want to utilize some blocks that would get destroyed after solving DF and DB, you can solve the right square (or even all of F2L) before solving DF and DB

(the rest of this solve wasn't included)Suppose you end up here -

Scramble: R2 U’ B2 R2 D’ F2 D B2 R2 D2 B F2 U L2 R U L’ R’ F2 D

Solution: z // inspection

R S R2 F’ U’ F // CP-line

u’ R u’ R U R u2 // 123

U2 R2 U R’ r U’ r // EO

R2 U' r U2 r' U2 r2 // 2-gen reduction

DF+DB took 7 moves. That's 7 moves just to solve 2 pieces, not great. But what if you did this instead:

z // inspection

R S R2 F’ U’ F // CP-line

u’ R u’ R U R u2 // 123

U2 R2 U R’ r U’ r' // EO

U' R' U' // Easy square

r2 U' r' U2 r' // DF+DB (2-gen reduction)

R U R // F2L

U R U2 R' U' R U' R2 U2 R U R' U R U // 2GLL
