A couple of points:
1) Regarding the original post, after the round Tiger said he was trying to bank the bunker shot off the face of the bunker and onto the fairway. He planned to bounce it to the right, but it bounced left. A reasonable choice, with an unlucky result -- except, I suppose, to Dan Jenkins.
2) Regarding the Snedeker drive (and the Phil ancient-history situation), would someone here please clarify the sequence under which a player may invoke the unplayable rule and replay the shot from the original point. To wit...
I hit a terrible drive into the gorse. Assuming the ball won't be found, I hit a provisional. (I gather that I must declare it so.) If the ball IS found, however, what are my options? If I choose not to identify my original ball, am I free to play the provisional? If I identify my original ball, may I (or may I not) play the provisional ball? If I identify my original ball, may I declare it unplayable? At this point, am I obliged to return to the tee -- probably to the exact place on the tee from which I drove -- and play another ball, under the unplayable rule? I assume I may NOT play my provisional under the unplayable rule.
Thanks.
