Matt: If I thought I was the best player in the world, there are 10-15 courses in the USA where I would want to play so the pretenders would be found out. In geographic order:
Brookline, Shinnecock, Bethpage, Winged Foot
Oakmont, Pinehurst No. 2, Kiawah, Augusta National
Oakland Hills, Butler National, Southern Hills
Riviera, PGA West
I'm sure I left out a couple because I did that much too quickly. The Golf Club might be one; Stonewall is relentless for scratch golfers, but it's not long enough for Tour pros. And Sebonack is going to be in there someday, too. It's tough as nails from 1 through 18.
