With a few notable exceptions (certainly #17), the front pin positions at St. Andrews are almost always the most interesting for me, because they demand the most precision in negotiating the humps/hollows/etc. in front of the green. I think the front pins on #'s 1, 2, 3, 4!, 5!, 6, 8, 11 (if over the Strath), 13, 14, 16!, and 18 might be the best on each of these holes.
