The Driver is the most important shot in golf. It sets up the hole for success and who doesn't love to hit one right down the middle!
Sometimes this need for accuracy can lead us to swinging with apprehension, or trying to 'steer the ball straight' by over-controlling the clubface. If you are steering the ball straight the result is often a push or sliced shot (ball going left of the target for right-handers). Technically the golfer is not allowing their club to release properly through impact, thus leaving the clubface open through and past the point of impact.
