I know Tizzard has more-or-less ruled the race out, but it would be verging on criminal not to let Cue Card take his chance, imo.
Connections might be comfortably categorised as "Please, anyone but that pair", but there is very little to dislike about Cue Card's overall form last season. He was as highly-tried as any novice chaser, and the list of horses he was beaten by is pretty impressive.
Accounting for a reasonable degree of progression, his OR of 160 might not be quite so harsh as it once looked, and with no problems on track, trip or ground front, I think he could go well in the race.
Connections won't find out much in the Haldon, and are planning to step him up anyway. Concerns about how 'hard' the race is are a bit bogus, imo - and a thoroughly genuine and consistent sort like Cue Card shouldn't have any problems giving his running.
I've had a small dash at 30 in the miniscule hope that connections reconsider.
I've also backed Al Ferof for similar form reasons; though given he's 120 on Betfair, I can only assume he is either OFS or a different target has been declared (I honestly don't know).
