Cupped Lead Wrist
What is actually happening
At the top of the backswing your lead wrist is bent backward (extended/"cupped"), which opens the clubface relative to your swing.
What it costs you
An open face at the top has to be saved on the way down — most players never fully square it, and the miss is the slice or the weak fade that will not hold its line in wind.
At the top, feel the back of your lead hand flat — like it could balance a dinner tray.
Motion-Check Top Pauses
Swing to the top and pause for two seconds. Look (or film) and set the lead wrist flat, feeling the difference from your cupped position. Ten pause-and-fix reps, then three swings without the pause keeping the flat feel.
Is this the one costing you shots?
Film one swing and the analysis checks for it at every position, on your video.
