King Yao

King Yao is the author of analytical gambling books. He keeps a Weighing the Odds blog (inactive since February 2009) and is a regular poster on Internet forums for sports bettors. He also writes a monthly sports betting article for the Two Plus Two Internet Magazine. Yao's books are published by Pi Yee Press, run by Stanford Wong. His two books are titled Weighing the Odds in Sports Betting and Weighing the Odds in Hold'em Poker. Since Yao left his trading position at Susquehanna International Group in 2000, he has been playing poker and betting on sports. Yao uses his experience in financial derivative markets and translates it into gambling for both his personal betting and his writings.

From 1992 to 2000, King Yao worked for Susquehanna International Group as a financial derivatives trader. His experiences includes trading equity options on the American Stock Exchange, currency options at the Bank of New York (in partnership with Susquehanna at the time in currency derivatives), crude oil and gasoline options at the New York Mercantile Exchange and CMO (collateralized mortgage obligation) derivatives for Susquehanna's proprietary account.
