Pebble Beach has hosted the Open three times:
1982 - Tom Watson defated Nicklaus
1992 - Tom Kite won
2000 - Tiger won in record fashion
and Pebble Beach is hosting again in 2010
Riviera hosted is 1948 I believe...
the biggest question heading into Thursday is the state of Tiger Woods' left knee...
If he's one-hundred percent he's the man to beat. I think we may have another obscure player a la Cabrera coming out of the pack though. The course has been set up extremely long - over 7600 yards - so look for the big hitters to come to the fore!

Sorry for the confusion. I got ecited, Lucy.
