Tisadream made the perfect start over fences, as she made all in the Pickardstown Rated Novice Chase, completing a double for Darragh O'Keeffe.
Successful over flights at the venue in June, the Henry de Bromhead trained six-year-old since disappointed at Cork.
Sent off the 11/10 favourite this afternoon, the chestnut daughter of Dubai Destination was sent straight to the front by O'Keeffe.
She wasn't fluent at the sixth and again four out, but maintained her advantage at the head of affairs. Pressed from the second last, she was ridden on the run-in and came home with two-and-quarter lengths to spare.
Chesterville (5/4) filled the runner-up spot under Jordan Gainford for Gordon Elliott, with Kilkeaskins First another six lengths away in third.
de Bromhead said: "She is a fine big mare. I'm delighted for the Byrne's, John owns her and his uncle Paddy is here today representing the family.
"She was really good and Darragh was brilliant on her. We will look for something similar for her now, another rated novice would be ideal. She probably likes that ground and we will see how long more we have it for."
