Are you facing an uphill lie with some green to work with? Many golfers are taught to lean with the slope, but I prefer to lean into the shot, no matter the hill.
Set up with your left knee bent, right knee tall, and head left of the ball. Pinch the club into the ground, squeeze the ball, and let it pitch up the hill.
There is no need for a full follow-through—just release the club into the hill and let the clubface lift the ball naturally.
