Flooring Porter wiped the floor with his Paddy Power Stayers' Hurdle rivals as he made all to clinch back-to-back wins in the Grade 1.
Gavin Cromwell's seven-year-old took up the running and never relinquished it in the face of such class competition as Willie Mullins' Klassical Dream and Nicky Henderson's Champ.
4/1 chance Flooring Porter made all last year in the Stayers' Hurdle and was able to take on similarly brave tactics, with no horse looking likely to catch the Irish raider.
Philip Hobbs' 11/2 shot Thyme Hill stayed on for second and 10-year-old Paisley Park ran his heart out to finish third at 17/2.
The Flooring Porter syndicate from Galway will be sinking a few jars in celebration on St Patrick's Day.
Winning jockey Danny Mullins told ITV Racing: "Everything went to plan. Big credit has to go to Gavin Cromwell - I love the horse but he's quirky. His training is the reason we're back here today again, Gavin's done a fantastic job with this lad all year."
"I wasn't too worried about the preliminaries, the more he gets into the season, the less gas is in his system. Gavin brought him over a few days early, he was a little bubbly one or two mornings but this morning we were very happy with him. He was relaxed and showing a spark again.
"It's funny going into a race at Cheltenham with such confidence in the horse, but we believed in him."
