4 Winning Chances here makes it $4 the Field by my reckoning.
And the one to back is the one that will be up front early.
I guess with all the room outside it , the Red must be most likely, but with all the room available to drift in, then the Blue is also a possibility.
Whichever of the 2 is available at over $5 will be the win bet here for my $10.
