On tight lies play the fairway wood from approximately the middle of your stance and forget about sweeping the ball off the turf. Position it like you do for a 5 iron. In my case that would be 1 ball dia. ahead of center.
Well,.....
You could play it that way, like an iron, but there is a better way.
Imagine that, instead of hitting the ball, your effort is directed at throwing your club toward the target. In throwing your club at the target, you would sweep the ground with the club before you let go of it toward the target.
Now, if you can make that motion with the club, you can make a swing the same way, without worrying about the ball. The ball just gets in the way of your fairway wood and happens to make a little journey. Your swinging of the club gets the club to swing down the line, back in, and up to a nice follow-though position. Ball just gets in the way.
If you can learn to make the swing out to the target, with the "marshmellow" just getting in the way, you should have no problem hitting a fairway wood. If you have some old golf clubs laying around, swing them out toward the target and let them go, to get a feeling of swinging to the target. Of course, you won't stop your swing there, you will let the club, if you hold on to it, swing up to a nice follow-through.
