Play chips toe-down off tight lies and into the grain
For tight lies around the green, especially into the grain, the guest stands really close and tall, sets the club toe-down so the heel lifts off the ground, and tries to hit it off the toe of the club. He says the point is that the grain can't grab the heel and make him dig or get stuck, and this is a key thing that helped his chipping on tight lies.
