My golf has been suffering from a bad slice and fade with the occasional hooks (driver only), I had a lesson with the pro at my golf club who told me to change my swing to a more outside to inside swing (4 o'clock) however this has only seemed to accelerate the slice which will probably be due to the face being open at impact? How do you think I could stop that best?
I have a strong grip, bad upper back posture and also my head moves during my swing slightly... could any of these be the problem?
Thank you if anyone has any advice, I've got a video of my swing if it helps:
