Make a wide takeaway,
especially of the right arm

Move the arms and the clubshaft, in a straight line towards the right foot, across the body.

Have no bend in the right wrist, and minimum bend in the right elbow, at the top of the backswing.

To create more clubhead speed.

To set up for correct downswing club path.

This move produces more efficient weight-shift for more power. When the right arm remains straight, it forces the left arm, and with it, the entire left side to move around the spine, shifting weight onto the right side.

The right shoulder is moved ‘out of the way’ to to prevent it from starting the downswing. Thus a correct, in-to-out downswing swing path is set up.

A wide top-of-backswing position permits the arms to drop down with gravity, far enough away from the ball, for the hips to then be able to lead the clubhead towards the ball at the desired shallow angle.

No right wrist bend till the top of the backswing also has the advantage of

keeping the arms and body connected.
