Black Creek's Biaritz is the most fun golf hole I have ever played. From the back tee (Messrs. Stein & Wicker buy their clubs from NASA)on a wet day this spring I had to take a 3-wood to try to reach the back tier. Fortunately, I hit a career shot. Unfortunately, it needed to carry one yard further or ten yards less! From the swale, it was an easy three-putt for bogey.
My home course has what I'd call a "stretch" Biaritz with a fairly broad but shallower mid-section that is most frequently pinned - similar to the modern biaritz described by Les Claytor. The mid-section is level with the fairway with the front and rear sections slightly elevated. A false front of only a couple of feet makes the front section the most difficult to hold since it is also the narrowest from front to back. It's fun to see if the ball reappears on the back shelf to a rear hole location, but just as much fun to hope it doesn't disappear over the front shelf when the pin's up front. Since the hole is a 580 yard par five, the third shot, typically from 110 yards, can either be played with a wedge or low runner regardless of the pin location.
GCA darling Todd Eckenrode was a member of this club during his stint with GR Baird so I'd welcome your insight here or via e-mail.
While the biaritz has been traditionally designed to receive a lengthy approach, I think it would work well on a short par four. Imagine a narrow strip of pinnable green in front of the Valley of Sin for example.
BTW, Doug and Scot were gracious hosts and are justifiably proud of Black Creek. GO!
