Pulled shots come from a closed clubface or the path swing, most players suffer from the latter as they start their downswing with their shoulders causing their path to go to the left
You can either set up to a bunker shot square to the target for a lower trajectory and more roll or open to the target line with your clubface at the target for a higher trajectory and softer landing
Visualizing the flagstick as a tall object can help you make more shots up to the hole
