joeydb, If you're interested in betting quinellas, you might take a look at an article I wrote in 2002, "Getting More Bang for your Quinella Buck"
http://www.blackjackforumonline.com/...t/Quinella.htm
The idea is that when quinellas and exactas are offered in the same race, you're presented with 2 different ways to bet a quinella: You can either make a quinella bet, or you can make 2 exacta bets in a proportion so that it acts just like a quinella bet.
The article explains how to determine which way will give the bigger payoff.
