[O.B.Left]

Flipping is often caused by having focus on the club head instead of the hands.

Yes agreed. Generally speaking, to throw the clubhead past the Hands will cause flipping.......but it is possible with Horizontal Hinging to not see the left wrist break down when doing so. Rare , probably done intentionally by a Master golfer but true. Now if you throw the clubhead past the hands and hold the face square to the target...the left wrist breaks. And that is anything but rare.
