"Be sure that your left thumb is always placed on the same line as pressure point # 3, and covered by the cup of the right hand. With strong grips, this places the Thrust of both #1 PP and # 3 PP On Plane" HK 7th Edition

A 10-2-B or strong single action grip is groovy for hitting!

As with everything in TGM it is about geometric alignments, not neccessarily achieving a two knuckle or three knuckle "look." The point of the grip (to me anyway) is to feel the sweetspot...so that I can swing the sweetspot on a pre-selected plane and deliver the sweetspot with a pre-selected hinge action...to produce a pre-selected special purpose!

If the hands are not properly aligned EVERYTHING is askew! Study 5-0 and the variations 10-2-A thru G. That to me is the very first thing to monitor and fix. Everyone would should use a selected "hands to plane."

I remember reading an article about Ian Woosnam shortly after he won The Masters. Apparently he was playing below standard coming into that year's tournament. His coach, or someone, noticed that his grip was more 10-2-A than it needed to be. He moved his left thumb to the aft side of the grip (a move no more than 1/2 an inch and he began to pure it! Why? He was now in touch with that pin sized center of gravity aptly nicknames "The Sweetspot." Don't you just love that feeling!
