Ok I've just joined BF, and from a quick look it seems its either win or lose bets. I can't bet to place, you see I'm a cautious, conservative and positive type. So I like to back a qualified Fav to place.

If the fav wins approx %32, it must lose approx %68.
So if one were to lay the fav one would have a %68 S/R, yes?
Or
If one were to lay the field, 10 runners and only one can win....

Surely its not that simple.
