Kuchar has a one plane swing ie he swings it back on the same plane he will swing down on, as opposed to the other picture who's plane is higher at the top but will drop down below that on the downswing.
H'mm.
I'm pretty sure that (according to Jim Hardy, the 'inventor' of the concept of 1 and 2 plane swings) it's the relationship of arms and shoulders at the top of the backswing that defines whether they are 1 or 2 planers. - and up to 12* above shoulder plane is apparently still a 1 plane - and not the plane of the swing itself. Heres's a good explanation of the differences (and promotion of another 'method'!).
Weirdly flat, but effective, is my best description of Kuchar's swing!
