Here's what you sent me, so everyone can see:
Okay, so I saw the first three moves just fine - in fact, I'm pretty sure I spent quite a bit of time with that sequence myself. The part I don't understand is: how did you figure out the next 4 moves: L' D' F R? To me it looks like all those moves do is break up what you've already worked so hard to build. It seems like the pairs you create early on don't even help in your overall F2L - 1. So how did you come up with L' D' F R?So, after taking a second look, I came up with this. I remembered making lots of pairs, so this makes sense.
B2 - pair (UR + URB)
U' D2 - sets up edges + pair (FR + FDR)
L' D' F R - sets up 2 pairs (UL + UFL) (UR + FDR, F' off))
U' D - combine 2 pairs + edge
L' - place edge
F B - solve
