Keep accelerating through the sand, strike the match
In greenside bunkers keep accelerating through the shot - the feel is 'striking the match' at the bottom while the chest keeps turning, which lets the club splash through the sand with a divot from front to back. Many players slow down into the sand and lose all momentum. Feel like you're working the club with a bit of right hand and match it with the body turn.
