Most golfers have trouble with shots from the green-side bunkers. They may know what to do, but executing is often a problem. However, a long bunker shot presents a different set of problems. Golfers may be unfamiliar with how to attack bunker shots from the fairway.
Take your normal stance when you are in the bunker. In the green-side bunker, you have to dig in with your spikes so you don't slip. But with the fairway bunker, you want to transfer your weight easily from one side to the other, so do not dig in with your spikes.
Hold the club at the top of the grip. The fairway bunker may require a full swing, and you can pull this out as long as your ball is not buried. If you are 200 yards away, take your 3-iron and use a full swing without trying to overpower the ball.
Take very little sand when you are hitting the ball out of the fairway bunker. When you are close to the green, you want to take sand so the ball will pop up and out of the bunker. Most fairway bunkers are not as deep as green-side bunkers and do not require a very high shot to get out of the hazard.
Take a long and sweeping swing when you are in the fairway bunker. You want your club to have a very shallow cut in the sand because you don't want to lose the energy on the swing.
Go to the driving range and hit out of the practice bunker. Hitting the ball out of the fairway bunker is much more like a fairway shot than hitting out of a green-side bunker. A normal swing with a shallow cut in the sand can result in a 200-yard shot to the green.
Tips & Warnings
Take a normal stance and don't dig your spikes in the sand.
