After going through the form for this Saturday, and finding multiple chances in each race, I have decided the best plan of attack for me is to have multi trifectas .
The guarantee of a wet track makes it even more difficult to find standout selections, and hopefully some roughies can fill the placings, or even win, and make the trifectas profitable .
I am basing the price of each trifecta on a 10% cost of the full price. Of course this could change slightly if there are scratchings, which I expect there to be.
Some of the trifectas I have selected are extremely wide, but with so much uncertainty, I feel they have to be, to try and snare a result.
I also realise that with so many selections in each race, that I am not going to get rich by betting this way, but that's not the purpose of betting this way. The purpose is to try and get some results, hopefully all of them, and look for some rough results.
