Bogey is the plan
A bogey on every hole is 90 on a par-72 course. Make one par and the card reads 89.
Protect the next shot
After a poor drive, get back into a playable position instead of trying a miracle recovery.
Take your medicine
One extra shot is frustrating. Turning it into three extra shots is what wrecks a scorecard.
Try this for nine holes
Aim for the center of every green and record how many doubles you avoid.
