Checkandchallenge is our selection at Nottingham, and the case rests on a progressive profile that suggests there is more to come, even though he is rated 4 lb below the top-rated Centigrade. That gap is modest, and a rising type can close it in a Class 1 contest over eight furlongs on heavy ground, where stamina and improvement often count for more than a small difference on paper. Centigrade is the chief danger, with Ebt's Guard and Room Service both rated 104 and just a couple of pounds behind him, so this is a tight, competitive renewal and not a confident call. Even so, Checkandchallenge is the one to side with.
