Big Chase Double Market

William Hill have launched a winning double market for this weekend's Betfair Chase and the William Hill King George VI Chase on Boxing Day.

As a previous winner of the big race at Haydock and the reigning William Hill King George champion, Silviniaco Conti is the shortest in the double market at 15-1. Cue Card and Dynaste who fought out first and second in the Betfair Chase last year are 18-1.

"There's very little between Cue Card, Dynaste and Silviniaco Conti so we're happy to lay them as singles for the weekend or as doubles with the King George," said William Hill spokesman Jon Ivan-Duke.

Taquin Du Seuil could be an intriguing outsider to win both races at 28-1, while Charlie Hall chase victor Menorah is 50-1 to add the feature races at Haydock and Kempton to his seasonal tally.
