Southfield Theatre just held on in a photo from the fast-finishing Polly Peachum to land the bet365 Select Hurdle at Sandown.
Paul Nicholls' consistent six-year-old cut out the running under Sam Twiston-Davies but his sizeable lead was worn down in the closing stages by Nicky Henderson's in-form mare.
Barry Geraghty, on a high after landing the bet365 Gold Cup, got a great tune out of Polly Peachum up the hill but she couldn't quite get to the Pertemps Final runner-up.
A short-head was all that seperated the pair at the line.
Nicholls said: "Sam said there was no pace in the race so he was going to pop him out in front, so I was very worried because he tends to idle but the plan worked out well.
"He's an exciting horse, he jumps well and will be an interesting one for next year. He jumps for fun and he's an improving horse.
"He will want three miles - that's his trip. He stays well and I can see him as a RSA horse."
