J.J.S.E
I think you are generally right about the lack of R&R on most Open courses, at least with today's technologies and today's championship set-ups. I personally think that Carnousite is at least as good as TOC in this category (2, 6, 17, 18, for example), and Hoylake used to be (haven't seen the new holes). Even Troon, with 1 and 11 (and who knows, maybe 2, 3 and 7 will be driveable when they go there next year. Maybe even 18, if the ground is hard and the wind is right......).
What slightly disapointed me in watching this Open (and the US one too) was that there didn't seem to be much thinkng involved by the pros off the tee. Rather, they agonised in terms of finding a club that would be more likely to hit the semi (god forbid that a "drive" should end up on the fairway!). No sense that IF they hit it consistently to certain places they would gain a series of fractional advantages which would allow them to triumph, if they converted. More a case of birdie/eagle the two par 4.25s (4 and 7), survival and hope for a few good bounces on the rest.
My take on Curtis, just from watching him, is that he played a "hit it, find it and hit it again" strategy. And, just as it usually does with us hackers (you are exempted form this statement, being a county player...), it actually worked! While Tiger struggled to find the green with wedges (shades of 1997-1998) Ben just moved forward, clamly and effectively. A very deserving winner.
