DogLicense:I would like to know why there are no " Unplayable, Lift & Drop OPTIONS"
"Thou shalt not have an option"
is my personal explanation. No unplayable, no dropping at the water, no change of balls, no position on the tee.
IMHO, it would have made game development uselessly complicated, and now we face a game without it. (Mulligans in pratice rounds may be a test for some change though).
