To try and keep this simple I would have to categorize it into two different groupings. High handicap players/beginners and low to mid handicap players.
The high handicap/beginners should look at a bump and run shot. It is a low running shot played with a 7,8 or 9 iron off of your back foot with a putting style motion. This is optimal when there is an opening at the front of the green and you don’t have to carry it over something.
The low to mid handicap player should get a reliable mid trajectory pitch shot with a sand wedge. Play the ball near the middle of your stance and make sure you strike ball then turf. The high flop shots look great, but are much more difficult to pull off.
