The Queen Mother Champion Chase revolves around Jonbon this season as Nicky Henderson's star finally looks set to earn his Cheltenham Festival stripes.
The JP McManus-owned Jonbon heads a field of eight runners gunning for the two-mile Championship event.
Henry De Bromhead's defending champion Captain Guinness joins two-time former winner Energumene for Willie Mullins amongst the opposition.
The latter proved no match for Jonbon in the Clarence House at Ascot in January, while Captain Guinness was perhaps fortunate to win 12 months ago and hasn't sparkled since on home soil.
Former Festival winners over hurdles, both Marine Nationale for Barry Connell and De Bromhead's Quilixios have stood their ground following final declarations.
Last year's Arkle second Found A Fifty and smart handicapper Libberty Hunter for Gordon Elliott and Evan Williams respectively are in the mix, alongside the surprise package of the season so far in this division, Joseph O'Brien's bold frontrunner Solness, who is bidding to make it three straight Grade 1 wins.
There are eight confirmed runners for the Champion Chase at Cheltenham.
