[O.B.Left]

To flip the Clubhead at Impact:

1. Slow or prevent the Right Elbow from Straightening
2. Run out of Right Arm

Open for discussion.

Number 2. does not guarantee a flip, necessarily.

It is possible to reach Both Arms Straight prior to Impact but Roll the flat left wrist to an early Finish Swivel without the left Wrist breaking down.........not the best of things for a long shot but if you look at the photo accompanying the Pause Minor Basic Stroke you'll see Horizontal Hinging and a Flat left wrist. 10-3-J PAUSE.

Now Id say that normally the guys on tour when using the Pause (intentional Quitting) employ Vertical Hinging and allow to their Left Wrist to bend (Intentional Throwaway) if you will. With a desired reduction to compression per 2-C-2 #3. Assuming an Arc of Approach procedure. Steering the clubface square to the hole.

Now Steering ........there is your real culprit to my mind, when considering the causes of flipping. Which is why Yoda told us "that the overtaking of the Hands by the Clubhead must happen and it will be either via a bending left wrist of flat ROLLING left wrist". Hence the italics on the word "ROLL" the only word so emphasized in the entire mission critical mechanical check list of 12-3.

If Steering the clubface is the cause of the bent left wrist then Rolling is the cure. There's a lot of force being generated, if you hold/steer the face with the left hand square to the hole.........that force can bend the left wrist. Unless you hold it rock solid and saw off your finish or something.

In regard to #1. I know that a Swinger feels something like that especially when getting to Pitch Elbow and Snap Release but from there you must Release , meaning the Right Arm is Straight at Follow Through , Both Arms Straight. If you dont do that you havent completed the clubhead full circular orbit.

It makes sense that if power is accumulated , delivered and then Released, a stifled release would not see the full application of all the potential power accumulated. There's a few schools of thought out there that teach a held off still bent right wrist and an inhibited release of #2 and 1 as well but while I can see it for short irons and mid irons I dont get it for the driver. That isnt ideal. Dont cook up a block to avoid a release problem , cure the release problem or suffer the associated loss in power. You know there's one fella that teaches that move......I saw a video of him the other day hitting a driver .....he Finish Swiveled it. Yup.
