Great Endeavour and Wymott are next at 6-1, ahead of Michel Le Bon at 7-1.
“The Hennessy looks to have been Aiteen Thirtythree’s long range target since his novice chase success at the corresponding meeting twelve months ago, and with the Paul Nicholls yard in top form, punters are banking on more big race Saturday success for the champion trainer,” said Coral’s David Stevens.
Elsewhere, Binocular is Coral’s 4-5 favourite for the Fighting Fifth Hurdle, ahead of Celestial Halo at 5-2 and Overturn, 3-1.
