Taquin Du Seuil found the quickest route through desperately muddy ground at Newbury to give trainer Jonjo O'Neill and jockey Tony McCoy their fourth Betfred Mobile Sports Challow Novices' Hurdle in 11 years.
The 13/8 favourite managed to finish nine lengths clear of Easter Day despite flattening the final flight.
Only beaten once in four starts since arriving from France, he looks likely to be rested until the Neptune Investment Management Novices' Hurdle at the Cheltenham Festival. "You'd have to be looking that way," said O'Neill. "He doesn't mind that ground, but I'd say he'd be as good a horse on better ground."
The well-fancied Clondaw Kaempfer dropped away in the home straight and was brought to a halt by Jason Maguire.
My Tent Or Yours had inflicted Taquin Du Seuil's only British defeat at Ascot in November and he was in action in the Betfred Mobile Lotto Charity Introductory Hurdle.
However, the 4/11 favourite finished four-and-a-half lengths adrift of his Nicky Henderson-trained stablemate Chatterbox (5/1).
Charlie Longsdon's Pete The Feat's continued his progress since arriving from Anna Newton-Smith's yard as the 15/8 favourite rattled off a five-timer in the Betfred Mandarin Handicap Chase to finish five lengths clear.
Luck was on the side of Module (7/2) in the Betfred "The Bonus King" Novices' Chase as Tom George's French recruit won by six lengths as McCoy was forced to perch uncomfortably aboard the runner-up Colour Squadron after his saddle slipped.
Philip Hobbs's Pistol (4/5 fav), which was unable to win on the Flat, bettered himself in the Betfred Hat Trick Heaven Juvenile Hurdle.
African Gold (4/1) maintained his pleasing profile for the Twiston-Davies family in the Betfred Goals Galore Handicap Hurdle.
Arbeo (4/1) won the Betfred Double Delight Novices' Handicap Chase for trainer Diana Grissell.
