The Nicky Henderson-trained eight-year-old was a brilliant winner of the blue riband at the Cheltenham Festival in March, but was beaten out of sight on his seasonal reappearance in the Betfair Chase at Haydock last month.
Kimmins said: “Thankfully he got to the track in one piece, despite all the awful weather.
“I think it is a big ask, but this was the obvious race for him to go for and that’s where we are.
“The vibes are good and Nicky is happy with him.
“It’s a very tough race and we’ll just have to wait and see what happens.”
Bobs Worth is not the only runner in the 10-strong field with questions to answer as Gold Cup runner-up Sir Des Champs suffered a heavy fall on his return in the John Durkan Memorial Punchestown Chase.
Jockey Davy Russell said: “We’ll make amends for the last day hopefully and get a clear round and we’ll see what way we’re going for the rest of the year.”
Gigginstown House Stud are also represented by the Mouse Morris-trained First Lieutenant, who ran a blinder to finish second in this race 12 months ago but performed well below par in the JNwine.com Champion Chase at Down Royal in November.
Morris said: “I’m hoping that we’ll see a different horse to the one we saw the last day.
