War Of Attrition made it two from two since returning from injury with an authoritative display in the Thurles Chase under Davy Russell.
The 2006 Cheltenham Gold Cup hero, who scored at Punchestown last month on his first start for almost two years, travelled strongly in second place under Davy Russell before taking the lead four fences from home.
From that point, the result was in very little doubt and the 2-7 favourite only had to be pushed out to score by eight lengths from Carrigeen Kalmia.
Victor Chandler were suitably impressed and cut the nine-year-old to 16-1 from 25-1 to regain his Gold Cup crown next March, with Blue Square offering the same price from 20s.
Totesport have held their price of 20-1, while William Hill are unchanged at 25s.
