Brian-
I've been looking at swing sequences of Snead and Hogan, as well as other "one-planers" in Hardy-speak, in particular looking at the right elbow and its relationship to the "shirt seam". Hardy proscribes as the initial move in the takeaway pulling the right elbow back to the seam, which also flattens the left arm against the chest. Jacobsen seems to do this, as do Hogan and Snead, though with them it is less obvious.
In contrast, many other "one-planers" seem to get the right elbow back later in the swing during the transition or even the downswing, when the body rotates counterclockwise and the arms fall "behind" the chest, something John Schlee says he learned from Hogan and calls the "world-class move" in his book Maximum Golf. This move is very visible in Sergio's swing.
My question is: what are the equivalent of these two moves under TGM, as well as the advantages and pitfalls of each?
Thanks,
Jeff
