Chacun Pour Soi resumed winning ways in the Ladbrokes Dublin Chase at Leopardstown.
Willie Mullins' lightly-raced eight-year-old looked a potential superstar when beating Defi Du Seuil at Punchestown last spring.
He did not reappear until Christmas, when he was surprisingly beaten by Henry de Bromhead's A Plus Tard and a rematch was on the cards.
However, A Plus Tard was a late absentee as De Bromhead felt the ground was too quick to run his charge and when Mullins' Cilaos Emery departed at the first fence, Chacun Pour Soi's task was further eased.
His main danger was stable companion Min, winner of the race for the past two seasons, but Paul Townend's mount breezed past him at the second last before keeping up to his work for a three-and-three-quarter-length win as the 6-5 favourite.
Latest Exhibition relished the step up in trip to win the Nathaniel Lacy & Partners Solicitors "50,000 Cheltenham Bonus For Stable Staff" Novice Hurdle at Leopardstown.
Always highly thought of by trainer Paul Nolan, the seven-year-old had run against some of the top novices this season and Nolan always suggested he would come into his own when faced with a proper stamina test.
Racing over two and three-quarter miles for the first time, he was the first of the fancied runners to come off the bridle turning into the straight, but he kept on responding to Bryan Cooper's urgings.
When Cooper asked him for a big leap at the last, his mount responded in fine fashion and the 7-2 chance powered away from the front-running Cobbler's Way to win by two lengths, with Longhouse Poet third.
Nolan was winning his first Grade One since Defy Logic took the Irish Arkle in 2012.
