The feature race on the third day of the meeting is the Group One Nassau Stakes over 1m2f and Joan Of Arc for Aidan O'Brien looks to have a huge chance.
The three year old daughter of Galileo was seen once as a juvenile when finishing a close second at Dundalk over 7f, but this season she has turned into a top tier Group One filly.
Starting her campaign off in March she landed a 20 runner Maiden over 7f and then went into the Group Three 1000 Guineas trial at Leopardstown and she was a fair sixth in a big field.
She was given another spin in a trial ahead of the big Irish Classic event and she won nicely over a mile this time at Leopardstown.
Primed for a big run at the Curragh, she was bobbed on the line by stablemate Empress Josephine in heavy ground, settling for second in the Irish 1000 Guineas.
O'Brien last time out stepped her up in trip for the Group One Prix de Diane in France and it saw her best performance of the season when taking the 17 runner event.
She will only improve for that run and handling all different conditions makes her one to be on side with.
