Muraaqaba stayed on best of all to come out on top in the German-Thoroughbred.com Sweet Solera Stakes at Newmarket.
Winner of her maiden on the July course in June, the Mark Johnston-trained filly returned to Headquarters on the back of a perfectly adequate fourth place in the Princess Margaret Stakes at Ascot.
Trying seven furlongs for the first time, Dane O'Neill had her settled nicely in mid-division and got a lovely tow into the race at the perfect point as Calypso Beat attempted to make all.
There were five in a line with a quarter of a mile to run, but Muraaqaba (7-1) got to the front around the furlong pole and put the race to bed from there.
The gallant Calypso Beat was a length and three-quarters back in second, with favourite Winters Moon third.
