Every coach in Las Vegas has met you. You hit it well on the range. Your buddies say you should shoot in the 80s. You shoot 95, and you can't explain it, so you book another swing lesson. The swing isn't the problem. Here's where the ten strokes go.
The double bogey is the whole story
Take your last five scorecards and circle every hole that was a double or worse. Count them. For most 95-shooters it's four or five a round. Now imagine those holes were bogeys. That's an 88 to 90, with the same swing, the same putting, the same you.
Doubles don't come from bad swings. They come from one bad swing followed by a bad decision: the recovery shot through a gap, the flag you aimed at from 170, the driver on the hole where driver brings water into play. The bad swing cost you one stroke. The decision after it cost you the second.
Three decisions that are costing you strokes
Aiming at pins. Your approach shots land in a cloud twenty yards wide. Aim at a pin eight yards from the edge and a third of that cloud is off the green, short-sided, where up-and-down is a coin flip. Aim at the middle and none of it is. You'll have a thirty-footer instead of a ten-footer, and a two-putt instead of a chip and two putts.
Hitting driver because it's a par 4. The club off the tee is decided by where the trouble is, not by the par. If the driver's cloud touches water or out of bounds, it's the wrong club, however far it goes when it goes straight.
The hero recovery. From the trees, the question isn't "can I make this shot?" It's "what happens when I don't?" Chip out to a wedge distance, make bogey, and move on. Bogey is a fine score. Bogey is what good players make all day.
What to do about it
Play one round where you aim at the middle of every green and never hit a club off the tee that can reach trouble. Count your doubles. It'll be the lowest number you've had in a year, and you'll have hit it no better than usual. That's the lesson. The rest is making it a habit, which is what my playing lessons are for, and what You Suck at Golf is about.
Questions people ask
Doesn't aiming at the middle cost me birdies?
A few. It saves you more bogeys and doubles than it costs birdies, by a wide margin, and the scorecard only counts the total.
When should I hit driver?
When the whole miss pattern finishes somewhere you can play from. Rough is fine. Water, OB, and trees you can't advance from are not.
Is this course management or just playing scared?
It's playing the odds. Tour players do it on every hole; they just have a smaller cloud.
