FOR SPIN: DON'T
The club should skid, not dig, at impact
Some players understand the trapping motion required to increase spin, but they do it the wrong way. They move the ball way back in their stance and try to pounce down on it. That doesn't work for a couple of reasons: First, it takes too much loft off the clubface; second, it drops the leading edge down (left) so the club digs instead of skids at impact. That steep, digging action means you have to make a very precise strike, or you'll chunk it. The skidding action gives you room for error. Try it my way: Play the ball up and think, ball then turf.
