Big Buck's: Extended winning sequence to 13 races.
Big Buck's extended his winning sequence to 13 in the Sportingbet Long Distance Hurdle at Newbury on Saturday
The 1-8 favourite was matching the feat of Bula and as the market suggested was never in any danger of defeat.
He was far from fluent at the third last but Ruby Walsh was soon able to look around for non-existent dangers.
He was allowed to coast home from the last to beat stablemate Five Dream (25-1) by five lengths.
Sparky May travelled well for a long way but was quickly beaten from the second last.
Nicholls said: "He had a gallop with Kauto Star after racing at Exeter the other day, and we've left plenty to work on as obviously we want him at his best in the spring.
"He pulls himself up and does just enough. If he does that he will last, as he is never going to do too much.
"He's got more speed than the rest, he stays better than the rest and he's just better than the rest, it's as simple as that."
Walsh said: "He's just an incredible horse, he's never out of second gear.
"He's a good, safe jumper touch wood, and he goes on every ground. He's just perfect.
"He's better than any pension at the moment isn't he?"
Winning owner Andy Stewart was relieved to see his star performer maintain his brilliant record.
He said: "I was more nervous today than I think I've ever been in my life, especially as I kept getting text messages from people saying 'unlucky, it's 13' and things like that.
"It was lovely to see him do that and it's great for racing.
"He will now go to Ascot for the Long Walk and then hopefully to Cheltenham for a fourth Ladbrokes World Hurdle.
"We've no intention to go chasing at the moment but after he finishes his season at Aintree, we will have a discussion but there are a lot of good chasers around at the moment."
Sky Bet left the winner at 4-7 to win the Ladbrokes World Hurdle for a fourth time in March.
