On one of the more obvious angles in handicapping involves a positive trainer or rider switch.
It makes all the sense that a horse who was ridden by a jockey with winning percentage of 5 percent in its previous start deserves increased attention when the circuit’s leading rider hops aboard.
Unfortunately, simply playing every horse that makes such a switch may not be profitable in the long run.
In this case, finding another reason or two to like that horse can increase your chances of cashing your bet.
