Tillie may have crafted his most gorgeous collection of bunkers at this low-key Bay Area hideaway that avoids publicity as steadfastly as its neighbor — The Olympic Club — embraces it. The highlight is the drop-shot par-3 7th, Tillie's favorite of all the holes he ever designed. Called the "Duel Hole," it was the site of the last legal duel in United States history, when State Supreme Court Justice David Terry shot and killed U.S. Senator David Broderick.

Given the edict to "build us a man-sized" course, Tillinghast did just that, creating a stern test for the ages with lengthy par-4s and frighteningly deep bunkers guarding imaginatively contoured, pear-shaped greens. Among its five U.S. Opens, Bobby Jones's miraculous downhill, 12-foot, left-to-right breaking putt in 1929 to earn a playoff stands out, although Fuzzy waving the white flag at Greg Norman in 1984 is a Hall of Fame moment as well. Geoff Ogilvy, left, got up-and-down to par the 18th on Sunday en route to his 2006 Open win.
