Maybe the question should be, why bet these big races at all when they are just a Bookies benefit?

Sure, if your lucky on the odd day it can be a good earn, but a quick look at the outcomes from the comp. shows that the bookies are doing nicely thank you and the punters in the comp. are not covering their outlay, In fact most [including me] would be losing heaps if it was real money we were betting. Plenty of zero outcomes too.

I'm very wary of the big races [and any country Cups] and keep my bets interest only mostly. Lining up form is a nightmare and form reversals seem the order of the day.
