Albert Einstein and Charles Darwin are Aidan O'Brien's main Commonwealth Cup hopes on the penultimate day of Royal Ascot.
O'Brien has surprisingly only been victorious in this contest once and also chucks in Brussels for good measure in an attempt to double his winning tally.
The Ballydoyle trio will have their work cutout, however, with Goldolphin's Wise Approach and impressive Sandy Lane winner Venetian Sun also bidding for Group 1 glory.

Just two months ago, Albert Einstein was shortened into favourite for the 2000 Guineas off the back of flattering comments made by O'Brien with regard to his ability.
Not only did he fail to line up in the opening Classic of the season, he has been defeated on all of his three starts this season.
However, the neck he was beaten by last time shows that he might just be delivering on his promise just at the right time.
Improve he must, though. The standard set by Venetian Sun is extremely high and on the evidence of her Sandy Lane win, she may be extremely difficult to defeat, especially in receipt of the 3lb fillies' allowance.
Wise Approach is not without a chance either, but he will have to show his absolute best (and maybe a little more) if he is to give Charlie Appleby a first winner of the week.
He was just touched off by Charles Darwin at this meeting 12 months ago and has lengths to find with many of his rivals when they go to post at 15:05 BST on Friday afternoon.
