Hitting a flop shot off a tight lie requires that you attack the ball with a steeper swing and open clubface so that the club gets under the ball and pops it up softly
When playing a bunker shot play the ball off your front heel and make sure that you hit only several inches behind the ball so that the bottom of your swing arc is directly under the ball
Create an imaginary line to the target when lining up your shot then aim with your eyes down that line in order to hit your target
