Overturn turned in another superb front-running display to keep his unbeaten record over fences intact in the Scottish Arkle Novices' Chase at Musselburgh.
Donald McCain's dual-purpose performer, sent off the 1-5 favourite following impressive rounds of jumping at Sandown and Doncaster, was soon adopting his customary trailblazing tactics and even with a circuit to go it was clear main rival Tetlami was struggling to keep tabs on him.
Jason Maguire continued to wind up the tempo heading down the back, with some fine leaps keeping the pressure on, and by the time he rounded the final turn Overturn was well clear. He safely negotiated the remaining obstacles in the straight to score by an emphatic 29 lengths.
Tetlami was the only other finisher, with Asaid refusing to start and rank outside Next Sensation falling when well beaten at the second-last.
McCain said: "We had a hunt round Sandown and then two-miles-three round Doncaster, and we have had to be fairly sensible in waiting for today. That's what he's been waiting for.
"He was smashing and Jason said he was magic. He's been waiting for the day when Jason jumps out of the gate with him.
"We always looked for a reason not to send him chasing. If he'd made one mistake at home we wouldn't have done it. He enjoys it, that's the main thing - from the first day he's schooled, he's done what he did here.
"He will go straight to the Arkle, I wouldn't put myself through that again! He's won on three different types of track now and that will stand us in good stead for a month's time.
"We've been second in a Champion Hurdle and we jump fences like that. I have respect for Simonsig, you have to, but we don't have to be scared of him. He may well beat us, but he'll know he's had a race, that's for sure."
Paddy Power trimmed Overturn to 7-2 from 4-1 for the Arkle Trophy at next month's Cheltenham Festival, a race for which Tetlami's stablemate, the Nicky Henderson-trained Simonsig, is 4-6 favourite.
