The left thumb is slightly to the right of center in that photo. It is not a weak grip. You can read the original article if you want.

I can readily accept the idea that horizontal hinging occurs naturally when a golf club releases naturally in a swinger's action. However, you didn't answer my two questions.

i) Why would a swinger employ horizontal, rather than angled hinging, if he wants to fade/slice the ball?

11) What type of hinging action will result in a perfectly straight ball flight if the clubhead arc is perfectly symmetrical to the ball-target line and the clubface is square to the ball-target line at the exact moment of ball-clubface separation?
