Hey Ranch, in addition to the answer M & P gave you above, there is an option that you can select once you have made a bet that will give you the SP if you bets unmatched at the start of the race. If you click on the "My Bets" tab you should see it, although it does not always appear as an option...
Just been looking through the various posts. Impressive tipping MJA. well done !!
Nor me but I'm gettin a smile. Should get back on topic I suppose.
