R U'              // 2p (2/2)
F' # D B2 R       // X-Cross on R\DF (4/6)
(F') F'           // shift for diff case (1+1/8)
(B D2 B D2 B2)    // F2L-1p on R-DB + sq on L (5/13)
(L' B D' B' D L2) // F2L on R, leaving 3c on L (6/19)
# = [F U F', D']  // insert 3c comm (8-5/22)

rewrite: R F' D' F U' F' D2 B2 R F' L2 D' B D B' L B2 { D2 B' D2 } B' F
{ = S' // insert slice (2-1/23)
} = S  // insert slice (2-4/21)
============================================================
intentially avoiding inverse and NISS, I found this:
F' D' R2 U F       // EO on FB-axis + sq on Luf + sq on D (5/5)
D2                 // 2x2x3-1e on FL-UF (1/6)
R D B2 L U @ L' D' // F2L-1e on F-DR (7/13)
R D' R' D B2       // all but 3c (5/18)
@ = [U R' U', L]   // insert 3c comm (8-2/24)

final: F' D' R2 U F D2 R D B2 L U2 R' U' L U R U' L2 D' R D' R' D B2
