The two keys to achieving this goal are to a) make sure your clubhead makes clean contact with the ball and b) select a safe escape route to your target that’s ahead of where you would have been with a better swing.
If you currently don’t use a preview stroke try it — and give it a least a month. Always make your preview strokes while focusing on your aim line and visualizing the putt’s roll from start to finish.
And not insignificantly — it’s six times more important. Even if your path is good unduly opening or closing the face at impact spells doom. Catching putts across the face produces varying ball speeds. Find one impact point. My recommendation: the sweet spot.
