I’m sure there will be multiple ways this will be described, but I will tell you how I was taught. To keep this simple we will describe a right handed golfer.
To intentionally play a fade, a left to right shot, set up with your stance aiming slightly to the left of your target and aim your clubface at your target. Making the big assumption that the golfer can bring the clubface back to it’s address position, swing the club down your stance line which should impart some left to right spin on the ball.
To intentionally draw the ball, a right to left shot, set up with your stance aiming slightly to the right of your target and aim your clubface at your target. Swing the club down your stance line which should impart some right to left spin on the ball, if the clubface comes back to the square/proper position.
Another way to say the same thing is to visualize a clock. The right handed golfer would be at 9:00 o’clock.
To fade the ball set the clubface at 6:00 o’clock and then have your stance set up from 5:00 o’clock to 11:00 o’clock. Swing the club down your stance line which should be from 5:00 to 11:00. Return the face back to 6:00 at impact and this should impart left to right fade spin.
To draw the ball set the clubface at 6:00 o’clock and then have your stance set up from 7:00 o’clock to 1:00 o’clock. Swing the club down your stance line which should be from 7:00 to 1:00. Return the face back to 6:00 at impact and this should impart right to left draw spin.
This should apply to all clubs.
