Tarla readily justified odds-on favouritism on her return to fences at Limerick.
Willie Mullins' prolific seven-year-old struggled in a Grade One over hurdles at Punchestown on her last start, but was an entirely different prospect here.
Despite having fallen on her last two outings over fences, the Emmet Mullins-ridden Tarla made all of the running in the Irish Stallion Farms EBF Mares Chase to win by nine-and-a-half-lengths from Caheronaun.
Willie Mullins' son, Patrick, said: "Emmet deserves a lot of credit for that. She has fallen twice for Ruby (Walsh), but Emmet obviously gets on well with her.
"She is a dinger of a mare and has won 10 races now.
"She'll be kept on the go in mares' races over the summer now and she might even go back to the Flat."
