Chicago Grey was given a fine waiting ride by Derek O'Connor before coming out on top in the 141st Year of National Hunt Chase at Cheltenham.
The 5-1 favourite jumped accurately throughout the four-mile contest but still had plenty of work to do as the field skipped on down the hill for the final time.
Beshabar was the first to commit for home and the two of them approached the final fence as one.
But it was Gordon Elliott's Chicago Grey who got away from it the faster and he charged up the hill to secure a four-and-a-half-length victory.
O'Connor said: "John Earls, the owner of this horse, Gordon Elliott, and Paul Carberry have instilled faith into me the last two months.
"I'm just delighted to be here and I thank them all very much.
"He's an out-and-out stayer and jumps from fence to fence."
