Grip
A good grip leads to a good clubface, straighter ball flight and less compensations making the game much simpler.
The biggest problem I see is in the left hand. The thumb should not sit on the middle of the shaft, but slightly right of center. Instantly this gives the left wrist stability, strength and the ability to hinge and re-hinge through the swing.
Similarly I see problems with the right thumb sitting in the middle of the shaft, with the palm of the right hand aiming skyward. This will result in a lot of ‘topped’ shots off the fairway, which in turn encourages you to place the right hand even more under the shaft leading to hitting the ground before the ball.
The right thumb should be to the left of center of the shaft with minimum pressure.
I would encourage everybody, even if you were to have only one golf lesson in your life, to see a professional about your grip.
