A Quinella is a good bet to take when there is a reasonable sized π field ( i.e. 10 runners or more) and you are undecided about a couple of horses. The expected dividend in π a Quinella is generally bigger than taking those same runners in a Win or Place bet. For R$3 you can π pick 3 horses to run 1st and 2nd in any order.
