Some green side bunkers are more difficult to get out of than others. Take hole 10 at Bethpage for example. Hitting from this bunker (trap) is an extreme uphill shot. Wind will affect this shot and leave it short, way short 99% of the time. It's mostly a 30 yard or less shot with a 64 degree wedge, or (50 yards max distance) this is almost a full strength shot. I hit it about 90 to 95% and get a descent result compensating for the wind of course. The ball does not have a lot of roll, even with forward spin.
Watch for level lies from the bunker to the green. You can catch a flier or skull the shot. Take hole 2 at Bethpage for example. That bunker is relatively level with the green and if your 12 yards away, it's normally a 50% strength or less on a 41 yard max club (punch). Wind doesn't seem to affect these types of shots normally. Like it was stated previously, watch your lie % and allow for enough strength to make the shot effective. This is where practice comes in to play. Iconian wrote a great thread on this very subject.
Taylormade, 64 degree wedge = 50 yards max distance (full)
Taylormade, 64 degree wedge = 41 yards max distance (punch)
I have found the punch shot is most effective on distances of 20 yards and in from any lie, especially just off the green. Your shot results may vary with your club (wedge) type.
I hope everyone finds this helpful.
