I have a bit of experience playing, caddying, coaching, etc. on Pete Dye courses.
I think one of the things you can say about Pete Dye courses is that they're not just one thing.
For example, the two I might know best are the course in French Lick and Avalon Lakes in Warren, OH. The course in French Lick was difficult, and often in ways I thought were kinda silly. For example, on the par five third, the fairway maxes out at 25 yards wide with a 45° huge slope on the left and bunkers right, and at driver distances the fairway is under 15 yards wide, sloped at about 20° to the huge hill on the left, and… it just feels unfair. You can hit a drive up the right-hand side and roll it three yards into the left rough with the ball 18 inches above your feet.
And yet, Avalon Lakes is very playable. It's the kind of course where you can take on a lot more than you should and wreck your card in a hurry, or if you're on, really separate yourself from the field by pulling the shots off.
Kiawah Island isn't "too tough" unless the wind is just hammering you all day: solid strikes get through the wind okay and even if you stray a bit, the ball is often playable. Like Avalon Lakes, IMO, if you take on more than you're capable you can wreck your card, but if you're on top of your game you can separate yourself and score quite well. Like Rory at the PGA.
Sawgrass, we've seen some good scores. Great scores. We've also seen some train wrecks.
I don't think Pete Dye courses fit into one box.
But I'm still new to all this, so what do I know?
