▶ First and foremost, what matters is where the putter is aimed. Without near-perfect aim, I don’t think anyone could slip into blackout, even by accident. I set the putter down first with my right hand only. As I aim the face and look at my line, my feet settle into position. This is a point worth stressing: My body accommodates the putter’s position, never the other way around. Then I put my left hand on, beneath my right, to take a cross-handed grip. Everything should feel balanced, my weight distributed evenly in my feet and my shoulders level. I might take a couple of practice strokes, or I might not. What I always do is a little forward press – rocking the handle just slightly towards the target – to start my stroke. That press is my trigger, my cue, to let the darkness take over.
