"The weight was a key - he hasn't carried 67kg for a couple of years."
The eight-year-old Just Got Home settled behind the pace yesterday before moving into contention across the top.
He neatly cleared the final flight in front and drew clear to score by three and a half lengths to give his Welsh-born jockey Emily Farr her most important success.
"Well done to Emily, that was a perfect ride," Liefting said.
The Grand National and Great Northern Hurdles have already been ruled out for Just Got Home, who is likely to make his next appearance in the Wellington Hurdles, a race he won in 2014, at Trentham in a fortnight.
Race favourite, Ooee, ridden by Aaron Kuru who led two fences from home, finished second for local trainer Paul Nelson.
Wee Biskit made steady ground from the tail of the field for third for Matthew Cropp.
