No on the fast swing, not from next to the green. I have read club head speed is where the spin comes from, but I'm too chicken $#*! to swing hard next to a green.Are you putting a fast swing on these shots?
Do you use the firm wrist approach to chipping, or do you do the Phil M "hinge and hold"?
Have you tried laying the face open and swinging from out to in on a 45 degree angle?
I'm not sure what Phil does - other than hit impossible shots - but as much as possible I try to hinge my wrists on most short game shots. The closer the landing target, the less the backswing. It's a feel, but sometimes it's almost like letting the club head drop with very slow hands/arms.
Yes on opening up the face, but I haven't had a lot of success using that with my 56° sand wedge - maybe because of the bounce???? When I carried the 60° lob wedge, I could occasionally pull off a flop - meaning I could get the height and distance I was looking for form an almost full swing. But even on many of those, there was often more roll out than I thought there should be.
