Don’t baby a sand shot when you are short sided.  If your ball comes to rest in a greenside bunker and you do not have much room to land the ball on the green, do not try to hit the shot softly.  More than likely, you will leave the ball in the bunker.  The best way to play this shot is to open your sand wedge wide and smack the sand as if you were skimming a stone on water.  Slide the club under the ball with force and it will come out high and have a lot of spin.  Practice this short bunker play and it will come in handy.
