Get a feel for how hard to hit the ball, concentrate on the hole and make a loose stroke
Many slicers hit the ball to the right simply because they are lined up to the right, when they go to hit the ball their mind knows the target is to the left and then subconsciously changes the swing to outside in so that the club travels towards the target causing a slice
Aim to the right with a closed clubface to create counterclockwise spin on the ball
