Frankie Dettori can look towards Guineas weekend with a positive feeling about at least one Classic ride after the courageous performance of Sandiva in the Lanwades Stud Nell Gwyn Stakes at Newmarket.

Starting his first full season as the retained jockey of Sheikh Joaan's Al Shaqab Racing, Dettori has many fine horses to choose between on both sides of the Channel and even treated Rowley Mile visitors to a flying dismount, with the broken ankle from last October firmly healed.

Richard Fahey had already prepared Sandiva to win a Group Three in France as a two-year-old, and while bookmakers were not falling over themselves to cut her in 1000 Guineas market, she closed strongly to finish half a length up on Euro Charline and Majeyda when plenty went against her.

"I've got about 35 unraced three-year-olds to ride and there's a lot of travelling, but I'm enjoying it," said Dettori.

"We haven't seen the main ones yet, like Rizeena and the [Aidan] O'Brien ones, but at least my filly has come and done it.

"Where she was drawn [four] was a one- or two-length disadvantage and there was no cover, so it was a good performance. She is entitled to go to the Guineas with a good chance."

Sandiva is still as big as 25s with Betfred for the main event and could yet be joined by Marco Botti's Euro Charline, who also looked like she would appreciate a little further than this seven furlongs.

Barry Irwin, who runs the owning Team Valor syndicate, said: "She was finishing very fast and I very pleased. Marco wants me to supplement her for the Guineas.

"I will think about it but she is also in the Irish Guineas, so we will see."

Charlie Appleby will delay a decision on whether Majeyda joins her on 4 May.

Dettori's ex-employers Godolphin, and Appleby's colleague Saeed bin Suroor, could have a legitimate Investec Derby colt on their hands as True Story (5-2) mauled his opponents in the ebm-papst Feilden Stakes.

The July course maiden winner stretched seven lengths away from 15-8 favourite Obliterator, who showed great promise himself to finish well ahead of the remainder.

Now just 14-1 for Epsom with Ladbrokes and Coral, the son of Manduro will take in a Derby trial.

"I think a mile and a half will be his best trip and he will go to the Dante at York, or Lingfield," said the trainer. "For the future, I think he is a Derby horse."

Ger Lyons said of Obliterator: "He was first off the bridle but we never have them fully revved up first time out and I am expecting him to come on bundles for the run.

"His next run will be in the Derrinstown and then I would have thought the King Edward VII at Royal Ascot."

Richard Hannon hopes Shifting Power can prove the exception of the fairly ordinary rule of recent winners of the CSP European Free Handicap.

The 13-8 favourite had a size advantage over his rivals but proved determined to get past Mushir and Aeolus by a head and a neck.

"He is a big horse and will have needed that. He wants a mile," said the trainer. "He is in the Guineas and will go for one of them. But which one I am not sure yet."

It had already been a good day for Hannon, who collected his biggest winner since taking over from his father in the £100,000 Tattersalls Millions 3-Y-O Sprint.

Magnus Maximus (25-1) raced prominently under Pat Dobbs and galloped to the line three-quarters of a length to the good.

Hannon said: "That was a pleasant surprise as I thought six furlongs would be too sharp for him. He has won a very nice race there and we can diversify with him a bit."

David Brown has been supplying Sheikh Fahad with sharp two-year-olds since Frederick Engels won at Royal Ascot three years ago and Mind Of Madness (13-2) looked one out of the same drawer as he sprinted four and a half lengths away in the Horsesource Seabuckthorn Conditions Stakes.

"I did think he'd win, he's very, very nice," said Brown. "He will go to the National Stakes at Sandown and then to Royal Ascot."

Further victories for unexposed three-year-olds from the seemingly endless John Gosden production line came from Provident Spirit (4-5 favourite) in the Alex Scott Maiden Stakes and Munjaz (11-8 favourite) in the NGK Spark Plugs EBF Stallions Maiden Stakes.

There are no firm plans for either.
