@mvmac Wow thank you for that explanation that is so helpful. I was definitely getting those two things mixed up. Upright and flat were absolutely what I was referring to, I had seen some pictures of Kuchar and he was one that stood out in my mind. I will definitely shoot for the middle ground between the upright and flat.
I also didn't really realize that the pro guys shifted from steep to shallow, but seeing those pictures really helps. Thank you!
I looked at the scorecard, and the issue isn't addressed on it. If you get a chance, you might want to ask in the pro shop about the status of the wood pilings adjacent to the bunker, is it defined as part of the bunker, or is it an obstruction. If it was me, in an informal situation (like most Myrtle Beach excursions), I'd have said to play it as an obstruction, under the rule that @Rulesman quoted.
