Ali Carter has revealed the impact Peter Ebdon is having on his mission to win the Betfred.com World Snooker Championship.

Essex potter Carter was a finalist in 2008, losing to Ronnie O'Sullivan, and his prospects of becoming champion at the Crucible looked doomed earlier this season when his battle with Crohn's disease became increasingly agonising.

But Carter, 32, has changed his diet and is back to feeling well again, as he demonstrated in beating Judd Trump 13-12 on Monday, and he said of Ebdon's support: "He knows what it's like to be world champion. He's been there and done it. I haven't and nor have a lot of players. He's got some invaluable advice for me and I respect Peter."

Ebdon was present in support of Carter, which 22-year-old Trump called "a bit strange". But Carter said the advice from the 41-year-old, who won the 2002 world title and lost in the first round to Ronnie O'Sullivan this year, had paid off.

"It's all very well having these sports psychologists. But they don't know what it's like to be out there playing under pressure. Peter does and that's why I respect him," Carter said.

"In the dressing room he's just giving me some words of advice and words of wisdom, and telling me a few things that might help in the tight situations, and sometimes any little edge you can get can be enough."

Trump said: "A lot of players enjoy me losing. Ninety-nine per cent of people are on my side and I take no real notice of any other players."

Last year's runner-up also said Carter was "childish" for applauding sarcastically at one point, as Trump laid a snooker with what appeared to be a huge slice of luck.

Carter, who will on Tuesday begin a quarter-final against Welsh surprise package Jamie Jones, claimed Trump had all the luck until the final frame, but repeatedly failed to apologise.

"Now he can know what it feels like to have a nasty scar in your career and it's not easy to get over," Carter said.
