Danny McIntosh hopes to propel himself back into title contention by winning Prizefighter on Saturday night.
McIntosh is a former European light-heavyweight champion, but he steps up a division for this weekend's cruiserweight tournament at York Hall in Bethnal Green, live on Sky Sports.
The Norwich man is determined to get back on track after suffering three straight defeats and is fully aware that victory in Prizefighter can transform a fighter's fortunes.
Past entrants such as Martin Rogan, Ovill McKenzie and Audley Harrison landed big fights after winning the competition and McIntosh hopes to follow a similar path.
"It's just a case of taking a chance when it comes along," he told skysports.com. "These guys I'm fighting at Prizefighter, they are former British title level, but I believe I'm past that level.
"I don't believe I'm better than any of the guys there. I'm just going to say, I'm in it to win it.
"If I win this, I want the British title. I think when I'm on form, I'll beat all of them. That's not being big-headed, I just believe that."
McKenzie won the cruiserweight contest in 2009 after stepping up in weight and McIntosh believes he can repeat this feat if he sticks to his strengths against naturally bigger men.
He said: "A few of the guys there are pretty heavy-handed being cruiserweights, but I'm going to have speed, agility, accuracy all on my side and I'll be fleet of foot.
"It worked for Ovill McKenzie when he won, the speed of his hands and his feet."
Former British title challenger Shane McPhilbin is also targeting the trophy along with Wadi Camacho, who suffered his first defeat against China Clarke in March.
Neil Dawson enters the tournament on a high after blasting out the previously unbeaten Tony Conquest in a round, while Nathan Owens and Conall Carmichael are yet to suffer a defeat.
Hari Miles and Martyn Grainger complete the field at the famous London venue.
