Newmill takes honours.
John Joseph Murphy's eight-year-old, who is also entered in the Smurfit Champion Hurdle, took up the initiative from runner-up Mossy Green at the final fence to score by four lengths.
"He settled and travelled well and I was happy with the way things panned out," said Murphy.
"He is best fresh and better ground would also be appreciated.
"The Champion Chase could now be the plan without another run beforehand.
"The owners are keen to run him more often but that would be my plan anyway.
"He's probably best at two miles and though people have said he is soft in the past, he is actually as tough as nails."
In contrast to the 5-1 winner, Queen Mother Champion Chase contender Hi Cloy, who was sent off the even-money favourite, was struggling a long way from home and finished well adrift of the principals.
However, his trainer Michael Hourigan felt the testing conditions had gone against his runner.
"The ground was a bit gluey and he ran a bit flat on the ground," said the County Limerick trainer.
"Andrew (McNamara) said he never really carried."
