If I back a horse to win and the 'public' is also selecting that horse as the winner and there is a sudden track downgrade due to rain to 'dead' and I notice the horse easing on the market quickly and another firming, then turning to my selections form I see 'DEAD 6-0-0-0', The horse duly runs 2nd. last so boy-o-boy are track cond't. important !!
