In what areas are you struggling? Are you thinning your shots, not getting the spin you need, inconsistent?
“They” say bunker shots are the easiest – I have not found that to be necessarily true – and what it takes is just trusting the bounce to dig out the shot.
For my it’s just trying to throw the sand to where I want the ball to go – the farther the sand shot, the farther I have to throw the sand with the club. I open up my stance and the club face and try to slide the club under the ball, hitting an inch or so behind it so I get the sand and not the ball. The bounce keeps the club from digging in and that’s where the thump comes from.
