Clan Des Obeaux wins King George VI Chase for Paul Nicholls as Verdana Blue ends Buveur D'Air's unbeaten rum
Clan Des Obeaux provided provided Paul Nicholls with a 10th win in the 32Red King George VI Chase at Kempton.
In an incident-packed renewal, for a brief moment it looked as if the 2016 winner Thistlecrack was about to roll back the years when he hit the front, but he ultimately had no answer after the last to a rival four years his younger.
Harry Cobden - in his first full season as stable jockey to former champion trainer Nicholls - was determined not to hit the front too soon and had the confidence to take a pull alongside Thistlecrack.
A fine leap at the last sealed it and while the Colin Tizzard-trained Thistlecrack gamely stuck to his task for Tom Scudamore, he was beaten a length and half by the 12-1 winner, who is part-owned by Sir Alex Ferguson.
Tizzard's Gold Cup winner Native River was under pressure for much of the race and stuck on for third, passing the winner's stablemate Politologue for minor honours.
There had been drama at halfway, when Bristol De Mai fell at the fence in front of the stands, badly hampering Waiting Patiently, who unseated Brian Hughes.
Coneygree ran well for a long way, but Might Bite looks a shadow of the horse he was when winning the race 12 months ago.
Clan Des Obeaux is now 12-1 from 50 for the Gold Cup with Betfair.
Earlier, Verdana Blue ended the long unbeaten run of dual champion hurdler Buveur D'Air in the Unibet Christmas Hurdle at Kempton.
Both horses are trained by Nicky Henderson, and they had it between them from the second-last, where it looked like 1-4 favourite Buveur D'Air was always just going to do enough to hold on.
He had made a terrible blunder at the third-last, hardly taking off, although it barely checked his momentum and Barry Geraghty seemingly had everything under control as he took up the running from Global Citizen.
However, Nico de Boinville had yet to ask the mare Verdana Blue (11-2) for everything and she was gaining with every stride after the last.
Buveur D'Air had not been beaten over hurdles since the Supreme Novices' Hurdle in 2016, and while he continued to respond for Geraghty, Verdana Blue had too much speed for him this time, providing Henderson with an eighth win in the race.
Henderson said: "It is a little bit (strange feeling). You don't want him beaten. Barry is very good. You say you are sorry and I mean that, I will say that to JP (McManus), too. But I know he will say all is fair in love and war.
"Thank goodness it was one of our own. Barry didn't think it made a whole lot of difference (mistake at third-last). It didn't stop him. He galloped merrily on. It is the second time he has gone through a hurdle. He said 'no excuses'.
"She is a very good mare and she always has been when you get her on decent ground, as she is no good on soft ground. Unless you can promise it will be good to firm it will be a waste of time (training for Champion Hurdle).
"The plan was to go for the £200,000 stayers' race (on the Flat) at Lingfield on Good Friday, as my jockey that day (when winning on the Flat at Kempton), Luke Morris, said that is what she will win."
He added: "Buveur will go to either Sandown (Contenders Hurdle) or Wincanton (Kingwell) as they are the only two you have got. Barry is not worried as he said he has won his race. Round here on that ground she is very good."
