A flexed lead wrist means the wrist is slightly bowed or flat at the top of the backswing. This position helps to keep the clubface square or slightly closed, which is ideal for most players looking to hit straighter or more powerful shots.A bowed/flexed wrist also helps create a more stable and structured position at the top, increasing the ability to maintain lag and deliver power on the downswing.
VS a bent or cupped lead wrist (where the back of the left wrist angles away from the forearm) which opens the clubface, making it harder to square the club at impact (ie, inconsistent contact, slices or weak shots).
(See Dustin Johnson or Jon Rahm, who utilize slightly flexed or bowed lead wrist at the top of the backswing to promote a strong, square clubface at impact.)
Supinating the left wrist on downswing and through impact also helps square the club face, increases power by delofting the club head at last second, and promotes a stronger release since your right arm can naturally straighten from this position

Hogan lead wrist/forearm supination on downswing technique was revolutionary to professional golf in a similar way that Galfond's range theory revolutionized professional high limits NLHE cash poker
