Close the Face
With a closed clubface and a neutral grip, the only shot you should hit is a hook. Make it easier on yourself by closing the face at address. This way you won’t have to rotate the face through impact, and you can take your normal swing.
Align to the Right
As you setup to it, point the clubface to the target. To hook the ball, you should align your body to the right of the target. You should be pointing in the direction of your initial ball flight. As you swing through, the ball will start down your line and move around the tree.
