Check your surf to level – if you right hip or right knee is kicking torwards the ball you will have a tendency to come over the top. OTT plus a closed face will cause pulls. Coming too much from the inside plus a closed face will give you a hook.
I find with me that my hooks come in when I stall out at impact and the arms come off the body. This will roll the club face over through the hitting area. If I roll the face early I get a hook, if I roll the face late I get a push.
See how it goes as you adapt to the new motion and see what happens after Chapter 3 when you start to apply pressures to your swing.
