Big O'Brien team set punters a tough poser at the Curragh

Multiple representation for Aidan O'Brien is one of the complications for punters attempting to get to grips with the Pick Six at the Curragh.

The Ballydoyle trainer saddles four of the eight runners in the Irish 1,000 Guineas (3.25), with Winter at the head of the market, having leapfrogged several stablemates with her victory in the Newmarket equivalent.

The first five fillies home in last month's Group 3 trial at Leopardstown renew rivalry and that form gives a chance to the Joseph O'Brien-trained Intricately, who failed to make any impact at Newmarket. Easing in the ground should suit last year's Moyglare Stud Stakes winner.
