Jockey Chris Munce's first winner since he returned from cancer treatment could be a horse to give him more success through the Brisbane winter carnival.

All carnival options are on the table for in-form gelding It's On The Pocket who scored his fourth win in a row in the Queensland Day Plate at Doomben on Wednesday.

The Lindsay Gough-trained It's On The Pocket ($11) edged past Carmora to win by a long neck.

Munce said It's On The Pocket's win was a timely one, coming just a week after he made his comeback at Eagle Farm after undergoing treatment for throat cancer.

"I'm feeling 100 per cent and it's obviously good to ride any winner but being the main race of the day and for Lindsay makes it that little bit more special," he said.

"I rode that horse early days when he was a colt and he probably didn't measure up but they gelded him and he's living up to their expectations."

The three-year-old is undefeated since Gough had him gelded at the end of his last racing campaign.

"He's going to keep improving with racing because he's still green and giggly headed but he's slowly getting there," Gough said.

Gough has a number of options to consider with It's On The Pocket for the remainder of the carnival.

"He's a lightly-framed horse and I'll make a decision where to head with him in the next few days after I see how he pulls up," he said.

"Whether we go to the Gunsynd Classic at Eagle Farm in ten days or freshen him up for the Fred Best Classic here next month I'm just not sure right now."

Jockey Michael Cahill said runner-up Carmora, who was heavily backed from $6.50 into $4.60 cost himself victory by racing greenly under pressure.

Jason Taylor who rode the $2.10 favourite Ninth Legion said the colt simply failed to handle the heavy going when he finished 10th, beaten more than eight lengths,.
