Zaidpour dug deep to claim the Bar One Racing Hatton's Grace Hurdle at Fairyhouse.
Ruby Walsh's mount showed a great attitude in going past fellow joint-favourite Voler La Vedette going to the last, after the star mare had moved smoothly to the lead two out, where long-time leader So Young made a mistake.
The Willie Mullins-trained Zaidpour soon mastered Voler La Vedette, who lost second on the run to the line as Monksland finished well.
A clash with Big Buck's looks in the offing for Zaidpour at Cheltenham in March.
Mullins said: "I think he's improved so we'll go along those lines (Ladbrokes World Hurdle).
"I doubt he'll take on Hurricane Fly next but he'll be entered in all those races.
"He has enough speed for two miles, but he has plenty of stamina, too."
"He's good enough to run in a Champion Hurdle but the obvious thing would be to go over a longer trip" - Willie Mullins
Mullins added: "It was a fantastic result and he's stronger this year.
"He's good enough to run in a Champion Hurdle but the obvious thing would be to go over a longer trip.
"It depends on what runners we have but I'd imagine he'll go further - over two and a half or three miles. Himself and Thousand Stars fall into the same kind of bracket.
"I have to give a lot of credit to Virginie who rides him out all the time.
"She does a lot of slow work on him and keeps him right as he had shoulder trouble when we got him."
