Sean, thanks for taking the lead with this great thread. I recently played two rounds at Renaissance, so it's still very fresh in my mind. Here are a few reactions so far:
This course has so much going for it, including scenic beauty, dramatic contour, perfect links conditions, and a spectacular set of greens. I agree with what others have already written about the width and penal nature of some holes. Marginal misses can easily result in lost balls or chip outs, which is frustrating. The course was a lot easier on the second round, because I knew where I could miss, where the ball would bounce, where I didn't need to hit driver, etc. Nonetheless, there are several holes that lack strategy and just require two straight shots. In my mind, this is probably the one factor that leaves this course slightly behind the very best courses. Among other Doak courses, for me, it's in the same league as Streamsong and Stone Eagle (pretty good company!) but behind Pacific, Ballyneal, and Barnbougle. Its high notes are as good as anywhere and there are no bad holes, but there are also too many unmemorable holes.
On the 10th in particular, I have to disagree with the criticisms. Perhaps it's lame to say that you love the one hole that runs along the ocean, but it's one of the best holes that I have ever played. Not only is the hole as scenic and dramatic as you find anywhere, but the hole exemplifies strategic golf.
Think about the 5th hole at Merion, one of the greatest holes in the world and often lauded on this site for its strategic merits. If you hit to the left side of the fairway, challenging the creek and taking a risk, you get a shorter approach from a flatter lie and a better angle into the severely sloped green. If you bail out to the right, you get a longer approach with the ball above your feet and a worse angle into the green. Unfortunately, Merion has diminished some of this hole's strategic value by narrowing the fairway and pushing the tee back to 500 yards, but the concept is still a great one. In my view, the 10th hole at Renaissance executes this concept even better than 5 at Merion, and instead of a little creek, you have to worry about a cliff edge and an ocean!
Sean and others criticized two features of this hole: the left side of the fairway is blind from the tee and the green is too severely sloped. Personally, I think these are great features. The rewarding, left side of the fairway is supposed to be hard to hit, and the partially blind tee shot adds to the challenge and excitement. Furthermore, the severity of the green is essential for the strategy of the hole to work out. You want it to be very difficult for the player who bailed out to the right to be able to hold the green with his/her approach. In my second round, I bailed out way too far to the right, and I was left with a 170 yard approach with the ball way above my feet, a rock-hard right-to-left sloping green, and a terrible angle. I hit the best shot I could and had to watch it roll off the back-left corner of the green, but I loved it. That's precisely the penalty I deserved for flailing my tee shot to the safe part of the fairway. In order to fully embrace the strategic merits of the hole, I think you have to accept the severity and accept that fact that a mediocre shot or a conservative line off the tee will force you to face a much more difficult approach.
I should also say that I spent some extra time chipping and putting around this green, and I found it to be tricky, challenging, exciting, etc. but also playable. While there are no dull putts or chips on that green, and while you certainly don't want to be in the junk to the right of the hole, you still have a decent chance at saving par from anywhere within reason.
On the walk back to the tee, I would say that, in general, I don't like walking back to tees but I'm happy to make an exception in this case. First, the walk is beautiful and serene. Second, the walk gives you a chance to see the fairway so there are no surprises even though the tee shot is partially blind once you get back there. Third, the hole is good enough that the backtrack is worth it.
For all of these reasons, I'm willing to say that #10 at Renaissance is one of my favorite holes. Maybe it's cliche to love the dramatic, beautiful ocean hole, and you'll have to take my word for it that it's not just the eye candy that's making me say this. I look forward to more discussion.
