Its getting complicated now. I have been to 2 rules seminars and my understanding is that as long as the provisional is farther from the pin than the original, if you hit the provisional and then find the orginal you can play the original and discount the provisional strokes. I also thought you were under no obligation to look for your original ball if you wanted to hit your provisional. Now if a partner finds the original ball and it is unplayable I'm not sure if you are obligated to play it. If it is ob than you could simply use the provisional, or if it is unplayable than proceed under unplayable - 1) move 2 club lengths and drop 2) move back in line with the pin and ball as far as you want or 3) go back to the tee. Do I have this right??
