Gran Geste got up in the shadow of the post to deny market rival Cask Mate in the Irish Stallion Owners EBF Maiden Hurdle and make a successful jumps debut at Navan.
Barry Geraghty came with a power-packed finish on Liz Doyle's four-year-old, who also won a Thurles bumper in October, to grab the 6-4 favourite in the final strides and snatch the verdict by a short head on the 9-4 shot.
Doyle said: "He was a bit green up the straight but seems to cope with the ground fine. I think there is a lot of improvement in him.
"He was green in Thurles and on and off the bridle, and the same up the straight today. We like him a lot and hopefully he can go forward from here.
"We are just taking baby steps with him so hopefully he can improve again.
"That's my first runner today for JP (McManus). I don't know where he will go next. Today was nervous enough!"
Diamond Cauchois justified strong support to take the 29,500 euro first prize in the Tara Handicap Hurdle.
The six-year-old had shaped full of promise when third on his first run for Gordon Elliott five weeks ago and showed he had come on for that by asserting in the closing stages.
Pulling clear on the run-in under Davy Russell, Diamond Cauchois (6-4 favourite) went on to score by eight lengths from Fine Rightly with Grand Partner four lengths away third.
Elliott said: "He ran a nice race at Naas, we were hoping he'd come on from that run and he did.
"He'll probably go for the Pertemps qualifier over three miles now at Leopardstown."
