Big Zeb won the Paddy Power Dial-A-Bet Chase at Leopardstown for a third time when getting the better of Noble Prince.
Colm Murphy's top-class two-miler took this prize in 2008 and 2010 and obliged again with Robbie Power in the saddle.
The 8-11 shot powered past Noble Prince on the run to the line to score by a length and a quarter, with Forpadydeplasterer third.
Forpadydeplasterer made the running from Noble Prince, with Golden Silver and Big Zeb together in third and Scotsirish last of the quintet early on.
Tony McCoy made his move on Noble Prince about three fences from home but it was covered by Power on Big Zeb.
The pair jumped the last together, while Forpadydeplasterer made a mistake which put paid to any chance he might have had.
Noble Prince battled hard, but Big Zeb held all of the aces.
There was a nasty incident at a fence down the back straight when Golden Silver, the winner in 2009 and runner-up 12 months ago, took a very heavy fall.
