Last season's Lowther Stakes winner Queen Kindly will face ten rivals in Saturday's Dubai Duty Free Stakes at Newbury, her first attempt at seven furlongs.
Owner Jaber Abdullah will be on hand to see if the daughter of Frankel can extend her brilliance over an extra furlong, while her chief rival in what is still widely referred to as the Fred Darling Stakes, Dabyah, is already proven over a mile, having finished third to Wuheida in in the Prix Marcel Boussac at Chantilly on her final start at two.
Dabyah carries the red and white silks of Abdullah Saeed Al Naboodah, whose Daban struck at Newmarket on Wednesday.
Bruce Raymond acts as racing manager to both men and believes Queen Kindly is not guaranteed to appreciate the extra distance.
Raymond said: "She's done exceptionally well. She was always a big filly but is much stronger, and Richard [Fahey] says she's working very well. It's just debatable whether she'll get the distance."
Queen Kindly was sent off a well-backed second favourite behind Lady Aurelia in the Group 1 Cheveley Park Stakes at Newmarket but was unable to land a blow behind Brave Ana and her Lowther victim Roly Poly.
"I think she may have gone off a bit by the time of the Cheveley Park," said Raymond. "She sweated a bit that day, which is unlike her, and I felt it wasn't her running. We feel she has definitely trained on and it is just a matter of whether she stays."
Raymond has already visited the winners' enclosure on behalf of Alboodah once this week and is hopeful Dabyah is capable of emulating the form of Daban, who struck in the Nell Gwyn for John Gosden and Frankie Dettori.
While the Boussac winner Wuheida is curretly on the sidelines, fourth placed Senga advertised the form in the Group 3 Prix de la Grotte on Sunday.
"Dabyah is working exceptionally well, as was the filly who won yesterday [Daban], though they don't work alongsides," said Raymond. "She has already shown her qualities at Chantilly last time and we're very hopeful for her. She is assured of getting the trip whereas with Queen Kindly it is debatable."
Four colts were vying to head the market after ten were declared for the JLT Greenham Stakes.
Autumn Stakes runner-up Zainhom brings the best pattern form and faces two promising Godolphin maiden winners in Barney Roy and Dream Castle, while Aidan O'Brien sends over recent Dundalk winner War Secretary.
Simon Dow has not enjoyed too much pattern success in recent seasons but will be represented by the progressive Mr Scaramanga, who landed a big pot over a mile in Qatar before going down by a neck to Law And Order in a Lingfield Listed race earlier this month.
"It is a big ask but we felt we would like to have a go at level weights in a race on a flat track over seven furlongs before we finalise our summer plans," said Dow, who enjoyed one of his biggest career successes at Newbury over the round seven furlongs when Young Ern dead-heated in the 1994 Hungerford Stakes.
"It seems a lifetime since that but at least we are going back to the scene of our former glory," he said. "While Mr Scaramanga is fit and bright and in great order, we thought we would make the most of our opportunities, especially with the fast ground, which he will love."
A stone's throw from Dow's yard in Epsom, John Gosden is reponsible for four of the 17 entries in Wednesday's Investec Derby Trial, with Frankie Dettori's name already appended to that of Cracksman, the general 16-1 third favourite for the Classic.
