The very first thing I would notice on this scramble is that simply by doing the turn U' I can form a 2x1x1 out of the green/white/orange corner and the orange/white edge.

The second thing I would notice is that it is relatively easy to make a 2x2x1 after making the 2x1x1.

we've found a 7 move solution to the 2x2x2 in BR.

Step through this last solution move-by-move to see the change. If you notice, our seven move solution has to do three moves to place the middle layer edge and line up the 2x2x1 with it. This is pretty inefficient. If we look ahead just a little bit, we can see a way to complete the 2x2x1 and align the green/orange slot into it's correct position at the same time. This saves us one move from our previous solution. Watch the two solutions carefully to see the change.
