Ubak returned to the scene of his most significant success after claiming his first win of the season in the Gaskells Waste Management Handicap Hurdle at Aintree.
Although pushed along for a stride or two mid-race, the Gary Moore-trained eight-year-old appeared to appreciate every yard of the step up to the extended three-mile trip.
Having shown a return to form back over hurdles on his last two starts after failing to fire over fences earlier in the campaign, the 16-1 shot, winner of the 2013 Mersey Novices' Hurdle at the National meeting, moved through to pass long-time leader Rock The Kasbah between the final two flights.
While favourite If In Doubt flashed home under Barry Geraghty, having hit a brief flat spot, he could not make up the ground required to catch Ubak and Josh Moore, with a length and three-quarters splitting them at the line.
