Beantown produced a game front-running performance to claim the Joseph O'Reilly Memorial Hunters Chase.
Declan Queally 's mount was headed three from home but plugged on well down the straight.
He got back to the lead at the last as Private Developer fell and had too much in the locker for Hi Cloy who chased him home by three lengths.
"Some of his form in the past is very respectable. His run here last year behind Forest Leaves was good enough. He seemed in good form coming here," said winning trainer Sean Aherne.
"He was also second at Cheltenham a while ago (National Hunt Chase). Instead of blinkers we tried cheekpieces and it might have helped."
