Threeunderthrufive took his stalking record to three wins from four attempts as he landed in the Class Two Novice chase in Doncaster for Paul Nichols and Adrian Heskin.
Six-year-old El Khaid prepared for the jump job with a final round of fencing, finishing off Fantasticas’ lead to win by seven lengths, with second-tier winner Emitom back in third place.
His early jump was slightly below par, but he quickly improved and had the row sailing the lead and pulling back between the last two lengths of the McNeill family.
It was cut to 10/1 at the National Hunt Chase in Cheltenham, a race that Champion Trainer Nicholls has yet to win.
Jockey Heskin felt the horse had improved further to open after the race, saying: “Maybe it’s the least good of the jump, but it’s a tough fence in Doncaster.
“You’re always in his turn a bit and he gets lethargic very easily so I think he just drifts and puts on a single medium jump.
“He’s pretty good at jumping but he’s never going to be that impressive and it looks like he keeps winning.
“I don’t think we saw him at his best today – there is more to come.
“If he’s running 20 straight lengths on the bridle, you’ll know what you’ve got but we’ve never really gotten to the bottom of this horse.”
