Sent off the even-money favourite to beat a deep field, the rain-softened ground suited the Kim Bailey-trained five-year-old as he made all the running.
“I was delighted with him, because we had no intention of making all, as he’s a horse who doesn’t do a whole lot in front,” said Bailey.
“To do what he did, I was very pleased. They looked a really nice bunch of horses in the paddock, so I was delighted.
“I’m happy with him over two and a half miles for now, I’d also have no worries about dropping him back to two miles on soft ground, so we’ve got plenty of options. I’ll just see how he comes out of the race first.
“Today was a big day for him going from being a novice hurdler to a novice chaser, but he did it very well.”
Paddy Power cut Vinndication to 20-1 from 33s for the RSA Chase and 25-1 from the same price for the JLT Novices’ Chase at Cheltenham in March.
And there was a winner of note in the getsbk.com The Super-Price Sportsbook Handicap Chase, with the two-and-a-half-mile contest going the way of the Lucinda Russell-trained Ryalex, who is missing his left ear.
