High chip shots

As a reasonably decent golfer (5 handicap) I really struggle to play a high chip shot. My chip and run shots are a strong point, but say I’ve got a 10-30 yard chip where I’m short sided or need to get over a bunker I find myself trying to use Dan grieves release 2 to get the ball in the air, but I frequently feel like I’m throwing the club at the ball and often thin it. Does anyone have some feels or tips for these shots?
