Funny you post this now, I just read that piece you wrote prior to you posting this.
I think "gimmick" holes have gotten a bad name over the years. Too often now I think people see holes that are not pan flat with all possible options laid out in front of them like a giant, green buffet as gimmicks. You named some of them in your piece, but I should say that several of the holes at any of the Bandon courses are "gimmicks" for those who do not understand options and thought on a golf course. Same with Pebble Beach, I guess 6, 8 and 9 are gimmick holes...
In truth though, I suspect that what we are really looking at here is another form of variety and simplicity. Sure, Mr. Doak and the rest could have gotten enough earth moving equipment to knock down the dunes on #3 at Old Macdonald but why? That adds another form of variety to the golf course.
I do think Mike Strantz went a little overboard with blind shots, Tobacco Road has maybe 11 or 12 depending on the lines you take, Tot Hill Farm has 7 or 8, Royal New Kent has 5 or 6, and Stonehouse has a few as well. But those just add to the variety and fun of those golf courses. Who says you have to be able to see the ball land every time?
