First off, Tiger didn’t share the most important tip of all in this instruction video.
Don’t short-side yourself where you are forced to hit a difficult flop shot.
Now, that’s far easier said than done. But, you really should be thinking about the safest/smartest place to miss a shot before you pull the trigger versus just swinging away at your approach shot.
Back to Tiger’s tip…
After reading your lie and making sure you have the confidence to pull off a flopper, let the club do the work and follow his simple technique. NOTE: We say simple, but you certainly need to practice his technique a session or two on the practice green before you let it rip on the course, especially with playing partners or windows on the other side of the hole.
Watch the video. Practice a bunch. And then take to the course what you’ve grooved in.
