Nickname made it five in a row when running out an impressive winner of the An Uaimh Chase at Navan on Saturday.
Martin Brassil's star, who sidestepped Cheltenham due to drying ground, may be put away for the season after the 13-length success over Central House.
Jim opened up a substantial lead in the early stages of the Grade 3 event and only came back to the field three out.
Central House took over with Nickname in close pursuit. Ruby Walsh sent the 4/9f into the lead over the second last and he pulled clear before the last for a convincing success.
'I didn't like to see Jim winging the last ditch and it was only at the third last he came back to them. That type of race is not great to watch,' said Brassil.
'He has a bit of class - he probably wouldn't be mad about that ground and was tiring a bit at the end. It's been a great season and that could be his last run unless the ground was right at Punchestown.'
Walsh was completing a double having scored on Heavenly Blues in the opening novice hurdle for father Ted.
The 4/5f hit the front after Bahrain Storm blundered badly two out and soon asserted. Miss Mason tried hard to peg him back but could only get within two-and-a-half lengths.
'He'll go to Fairyhouse for something, either the winners race on the Sunday or one of the novice races,' said Walsh senior.
Militant looked an exciting prospect when running out an effortless winner on his chase debut in the novice chase.
Andrew Lynch sat motionless on Jim Dreaper's charge as he jumped to the lead three out and cruised to a 12-length success from Glen Harley.
'That was a perfect round,' said Dreaper. 'Throughout his career he had problems with his jumping and the vets diagnosed him as having kissing spines, which he was treated for.
'We ran him in a winners race so he would have room to see his fences. Apart from winning it was the ideal race as the first chase is always important.'
The crowd gathered around to see Oliver Brady in action after 20/1 shot Kenilworth ran out an easy 10-length winner of the Bar-One Racing Handicap Hurdle.
Pat Hughes was 'delighted' with the run of Point Barrow, who stayed on strongly in the closing stages to finish third. He will head straight to Aintree for the Grand National.
Tailor's Hall always had too much in the tank for 2/1f Aitmatov as he stayed on strongly down the straight to run out a five-length winner of the 2m7f novice hurdle.
'I'm delighted with him, he is improving all the time,' said trainer
Jessica Harrington. 'He could go home now and go chasing next year as he is a soft ground horse.'
The biggest pot of the day was for the Irish Stallion Farms EBF Novice Handicap Chase final and Nina Carberry excelled when producing Hold The Pin to lead at the last and score bythree-and-a-half lengths.
