Races don't come much weaker than a Class 5 maiden fillies' handicap, so Sir Michael Stoute has identified a golden opportunity for DUBIOUS AFFAIR to make a winning handicap debut. She took a marked step forward over this trip (third) in a Chester novice recently and arguably has most to fear from the admittedly more exposed Vindolanda, who was in contention until very late on at Newbury (fourth) eight days ago.
