    I've got a case like this:

    DFr needs to be swapped with UBr, and
    DBr needs to be swapped with UFr.

    r2 will solve everything right? No. It will also mess up the centers.

    I need help. Thanks!
     
  2. You've parity; the fix is D' L' F l' U2 l' U2 x U2 l' U2 r x' U2 r' U2 l2 F' L D

    Edit: I can't read; ignore this

    I don't think that is parity. Parity is the r slice, after doing an r2 move, UBr and DFr are swapped. Doing the alg leaves UFr and DBr still swapped.

    Using normal r2, you can shoot to UBr, reach the buffer. Then break into a new cycle: UFr > DBr > UFr.

    r2 (r2 F RUR' d RU'R' d' F)*3

    Some alternatives:

    2U2 2F2 2R2 2F2 2U2 (not centre-safe)
    z' M2 2U M2 2U2 M2 2U M2 2U2 z (centre-safe)
    U' D' R2 U D 2R U' D' R2 U D 2R' (centre-safe)
