Class of the race doesn't really matter to me... the challenge is to pick the winner at decent value out of a group of race horses that are similarly graded due to class... ie open class horses race in open class races... maidens run in maidens, class 4 horses run in class 4 races , group horses run in group races.... no matter what the class the challenge remains the same...... it can be just as difficult to pick a winner in a group 1 race (EG FIELDS OF OMAGH 20-1 cox plate; DELTA BLUES 16-1 MELBOURNE CUP or even DANDY ANDY at 200-1 in an Australian Cup) AS IT IS TO PICK A WINNER in a maiden..... MY EXPERIENCE IS THAT LOWER CLASS races especially in country areas in distances from 1300 and above offer the best betting opportunities.....
