The Amazing Race 15

Maria Ho and Tiffany Michelle

Ages: 26 and 25
Hometowns: Arcadia, Calif., and Los Angeles
Occupation: Professional poker players
Relationship: Best friends

If Maria and Tiffany bluff about their profession as planned, the other teams may end up underestimating them -- a mistake! ... more The best pals play a man's game for a living and dominate, each having won the honor of being the last woman standing in the World Series of Poker's main event.

Not only are they smart, successful and highly competitive, they are used to pressure and cameras and are in good shape. They also hope to cash in on their celebrity with any poker fans along the way. Tomboy Tiffany is prepared to jump off buildings and eat anything, while girly Maria is efficient and a great negotiator. Maria's choice to bring a curling iron may be cause for concern, but these two instigators still rank as a pair the other teams should watch out for.
