Big Buck's has extended his winning streak to 15 races after a hard fought win in the Cleeve Hurdle at Cheltenham.
Starting the race as 1/4 favourite, the majority of people expected Paul Nicholls' legendary horse to record a routine race win.
However, Dynaste led by five lengths at one point and Ruby Walsh was forced to ask a big question of Big Buck's.
A trademark jump at the last saw Walsh ride him into the lead and complete his 15th straight win.
Nicholls said: "If we won today it was great, but if we lost I was the one who was going to get shot.
"He switches off in his races. Ruby said he was going to play it late today.
"He's such a class horse, he's get to the last, pricks his ears and goes."
Nicholls will be hoping for a simliar performance from Big Buck's in the World Hurdle at Cheltenham in March.
