Play your bunker shots with the same stance as your pitch shots; set up square to the target line and square the clubface to make this an easier shot
With a traffic cone behind you practice your downswing trying to keep the club inside the cone to simulate the correct approach at impact, this will help eliminate casting, over the top and other downswing faults that create curved shots and an improper impact position
Keep the ball low by taking more club, choking up, swinging softer and finishing low
