Usually you want to splash your ball and the sand out of a bunker, but when the ball is buried this will cause a skull, so in this situation you need to use your sand wedge to dig below the ball
When the ball is on an uphill or above your feet lie all you have to do is make some adjustments to your set up and stance
Use the Aim, Look and Go system to take care of your putting set up prior to the putt so you can clear your head of all thoughts and putt relaxed
