MrFunnyWobbl:
What about when you have no green to work with before the pin?
This is tough as unlike real golf it is hard to stop a ball quickly from a trap on WGT.
So this is where course management comes to the fore - play smart.
If in a stroke play round, I recommend get the ball out and do not get too cute - you have a much better chance sinking a longer putt than another shot from the bunker or rough.
It often depends on the hole (lie and elevation) and whether the landing area is downhill or uphill. The downhill landing is obviously the tough one and will continue to roll.
However if it is in match play, you may be in a position that you need to try for the one in a hundred shot.....and trying to catch the fringe or side of the bunker as alosso said is difficult and you will need to know your yardage extremely well...and have a lot of luck.
One thing Mr Fish said ^^^^ about shipping (agreed) and flopping. The flop can work very well on a couple of courses -Bethpage is one - so it comes down to trying our different shots on different courses. But flopping on other courses will lead to disaster, so learn what works on different courses and holes. Trial and error.
