I have been searching the Wiki, Web, and Forums for an algorithm to switch the corners on a 3x3x2 In Places FRU and FLU. I used to know it but I don't anymore, all the other corners are solved.
Then don't. It's perfectly intuitive, except for the J-perm at the beginning.
It's:
R2 U D' R2 U R2 U' R2 D R2 U' R2 to fix corners.
R2 U2 R2 U2 R2 to fix "parity".
U' (R2 F2 R2) U' (R2 F2 R2) U2 (R2 F2 R2) U' (R2 F2 R2) to do an intuitive edge-cycle.
y' R2 U R2 U' R2 y' R2 U' R2 U R2 - T-perm
y2 U R2 U2 R2 U2 R2 - fix edges
By the way, trying-to-speedcube..., after the J-perm, wouldn't it have been better to fix the two edges by just setting up the parity (two-edge swap) alg? Doing a two-cycle and then an "intuitive" 3-cycle is a bit much.
