Unbeaten Queensland mare Chakvetadze has been sent back to the barrier trials following her antics at Doomben on Saturday before her triumphant return.

Chakvetadze extended her winning sequence to seven in her comeback run but her reluctance to be loaded into the barriers attracted the ire of stewards.

Chief steward Wade Birch advised trainer Michael Nolan that Chakvetadze must obtain two barrier certificates or trial to their satisfaction before they would accept her nomination.

Leading jockey Larry Cassidy was having his first ride on Chakvetadze on Saturday and he said she was extremely temperamental before the start.

"She was in a foul mood behind the barriers and I asked for an attendant to stand at her head and that made her worse," Cassidy said.

Despite her barrier behaviour, Cassidy was highly impressed with the mare and declared her a Group One winner in the making.

"It takes a pretty special horse to win seven out of seven and she is a very good mare," he said.

"She's definitely up to Group One class and I'm very happy to be able to get on her."

Chakvetadze hadn't started since she defeated highly-rated Sydney galloper Desuetude in the Gold Coast Guineas in May.

Nolan was full of praise for Chakvetadze but remained adamant there were no immediate plans for his stable star.

"We'll take it step by step with her," he said.

"The only plan I had was her first-up run and I will be guided by her from here on in."

Nolan said he thought Chakvetadze was bound for her first defeat when she missed the start and was caught in an awkward spot behind runners approaching the turn.

"I didn't think she could win from where she was but she's very special," Nolan said.

"She has got a great turn of foot and she's obviously looking for further now."

While Nolan was unsure where or when Chakvetadze would have her next run, he did issue an ominous warning to potential rivals.

"She's nowhere near fully fit yet and there is plenty of improvement in her," Nolan said.

"I think she's at her best when she gets up to 1400 metres."
