At address, encourage an exaggerated upright swing plane by playing the ball back of the midway point in your stance. Also, set up very, very open. Next, weaken your hold on the club by moving both hands to your so that ‘V’s point toward your chin instead of midway between your chin and right shoulder. After checking that the clubface is square to your target, squeeze the handle a trifle more firmly with your left hand.
During the backswing, swing normally, following the line of you ‘open’ feet, knees, hips, and shoulders. The exaggeratedly rearward ball placement will get the club moving up quickly, prompting the proper narrow swing arc. On the downswing, the firm, weak grip will automatically delay the release of your hands in the hitting area. That, along with the ball-back position, will produce impact before the glade quite squares itself to the ball, so that, as you trap the ball against the face, you impact very sharp left-to-right cutspin. The ball will start slightly left of that flag, fly high, float back toward the target, and , on landing, practically stop on a dime.
