Terrefort stamped his class on the Betway Mildmay Novices' Chase at Aintree.
Nicky Henderson's grey progressed from winning a Huntingdon handicap to claiming Grade One glory in the Scilly Isles Novices' Chase at Sandown in February, and was last seen filling the runner-up spot in the JLT Novices' Chase at Cheltenham.
With that form having been well advertised since, Terrefort was the 3-1 favourite stepped up to three miles on Merseyside.
Daryl Jacob, fresh from a Grade One double at the meeting on Thursday, cut a confident figure in the saddle throughout and appeared keen to play his cards late.
Ms Parfois looked likely to prevail when striking on in the straight, but Jacob had not gone for everything on Terrefort and when he did, his mount responded generously to grab the lead and gallop three and three-quarter lengths clear after the final fence.
Elegant Escape was best of the rest in third.
