That’s all there is to it! I find it helpful to swap fearful thoughts (It would be awful to chunk this) for finesse ones (Just “kiss” the grass). Embrace the moment and be smooth. Oh and your lower body should work just as hard as your upper (weekend players tend to “deaden” their legs around the green).
To begin grip down very slightly on a low-loft club (in the photo I’m using a 6-iron). This effectively raises the bottom of your swing arc. Center the ball in your stance with your hands just in front of it at address.
You’ll need a 60- or 64- degree wedge with clean grooves (very important for creating spin). Address the ball as though you’re hitting a bunker shot with an open stance pointed slightly left of your target and with the clubface laid wide open.
