Tidal Bay got up in the final strides to land what looked an unlikely victory in a thrilling renewal of the Lexus Chase at Leopardstown.
Ruby Walsh got an amazing run out of the Paul Nicholls-trained gelding to pass several rivals on the run-in to give owner Graham Wylie a second Grade One on the card after Back In Focus took the Topaz Chase.
In a bunch finish, Tidal Bay (9-2) snatched the spoils from First Lieutenant with Flemenstar and Sir Des Champs just behind.
