With Woods stellar performances, it's perhaps more telling as to the noteworthy courses where he has either elected to not compete, did not comport with his major-centric schedule(s), has not experienced significant rotation or where has not performed well:
Kapalua Plantation
Riviera
Colonial
Harbour Town
Oakland Hills (DNP 2008, missed cut as amateur in 1996)
Shinnecock (WD as an amateur, t-17 in 2004)
Winged Foot (1997 t-29, 2006 -first tournament after Earl died, 1st Major missed cut)
Whistling Straits - Non-Factor in 2004 & 2010
Atlanta A.C. (t-29 in 2001, 3rd missed major cut in 2011)
Oak Hill (poor showing in 2003)
Carnoustie (a T7 and T12 isn't awful)
Turnberry (2nd missed major cut in 2009)
Troon
St. George's
Finally, I have to note that in general Woods is far, far from a mudder...his 3 Open Championships have come in the midst of comparatively benign conditions and has been decided blown off course when foul weather has reared...this is also true on USA where you never have seen Woods hoist a trophy with so much as a windbreaker on.
