Hi Malcolm
Even if I dont understand all that words in english now and here after my third glas of Scotch Whisky (It`s amazing, continue to destillate it, you Scottish Bravehearts!) Garys webside tips will surely help you a lot.
Second I wanna say is that expierience is unpayable. Try it all out, all those kinds of shots in any of those plenty situations, and you will have lots of fun here.
Third: A shot that goes high and then down quickly is the flop. You can also use it from bunkers. You have to give more power and aim it to the left side then, cause the ball will fly to the right side. Try out 17 flop for example for a 14 yard 30/40 bunker shot.
Have fun and enjoy yourself,
Friedel
