I line all my shots up the same way - for all
clubs and all shots.
1) I stand behind my ball and pick my target.
2) I pick an intermediary target on the same line, a foot or two in front of my ball.
3) I stare at the intermediary target as I move up beside my ball. Then I square my clubface to that target. As a left-eye dominant golfer, I close my right eye to ensure I'm setting up square.
4) I place my feet, keeping my clubface square.
5) One last look at my target, and swing.
How I select my target on the green:
I stand behind my ball, in a straight line from my ball to the hole. I stand so that I can see both my ball and the hole without moving my eyes. I then imagine putts, and imagine the break, and imagine the speed, so that I get a ball dropping center cup. When I 'see' that line, I pick a spot in front of my ball
on that line, and carry on with the steps above. Start the ball on that line with the right weight, and watch the putt drop.
