Dinoblue came out on top after locking horns with stablemate Allegorie De Vassy in the BBA Ireland Limited Opera Hat Mares Chase at Naas.
Both horses are trained by Willie Mullins and were joined by only one further rival as Thomas Gibney’s Must Be Obeyed completed the trio for the Listed event.
Allegorie De Vassy was the 5-6 favourite and Dinoblue an 11-10 chance, but it was the latter mare who took first place in a battle to the line.
The outsider was beaten when the first two home began to race, and they were split by the width of the track as they took the last obstacle almost in unison.
Dinoblue landed marginally in front, however, and stuck to the task under Mark Walsh to remain in the lead by neck at the line.
