Cadmium gained revenge over old rival Ornua, as he landed the Grade 3 Buck House Novice Chase at Punchestown.
Ornua, as he had done at Roscommon recently, set out to make all the running, with Ruby Walsh settling just behind the leaders on the Willie Mullins trained Cadmium.
Walsh became more animated with two to jump, but his mount responded and he edged into the lead approaching the final fence.
A safe jump saw Cadmium home and on the flat he pressed on to score by five lengths from Ornua, with Cubomania back in third.
“There is a fair chance that I’m blowing harder than the horse!” said Walsh.
“He did it well. It was hard to see how he would reverse the form with Ornua but I suppose a more galloping track, the two furlongs extra and the 3lb swung it in our favour today.
“That’s twice he’s won here. He’s a novice for another six weeks so you’d imagine he’ll come back here in a month’s time for the Craddockstown all being well.”
On his comeback, Walsh added: “I feel like coughing up half a lung at this minute in time but other than that we’re all right.”
