This involves much fine-tuning of the swing learned above in driving. You'll typically need to shorten your backswing and not push forward with quite as much enthusiasm to avoid over-shooting the green. This can be particularly challenging on chip shots from just off the green, where distance is vital. One major difference between the two swinging styles is the absence of that slight pause at the apogee. Hesitating while taking approach shots throws your rhythm and control completely off, and typically results in firing long or short.
Hazards are, well, extremely hazardous.
Landing in a sand trap or even in some light rough can be absolutely murderous. Both are treacherous because of their unpredictability. It's almost impossible to know how a little bit of long grass or sand will affect your swing. About the only sure thing is that swinging hard to accomodate the terrain is a sure recipe for disaster. This is the exact opposite of most other golf games, where hazards will usually just impede your distance a little bit.
