Kerry Lee once again showcased her abilities at training staying chasers when Goodtoknow led home stablemate Mountainous in the 188Bet Handicap Chase at Hereford.
Last season alone Lee won the Welsh National, Warwick's Classic Chase and the Grand National Trial at Haydock.
The two stable companions were cut in the betting for that marathon event on Merseyside later this month by Bet Victor, with the winner now 10-1 from 16s and former Welsh National hero Mountainous 16-1 from 25s.
Lee also has another string to her bow for that race in the shape of last year's winner Bishops Road.
Having hit the ground running in her first season last term, this campaign has been slower to get off the ground but since the turn of the year there have been signs of a return to peak form.
Goodtoknow (4-1 favourite) was last seen finishing second to Grand National candidate One For Arthur in the Classic Chase and was was never far from the pace-setting Federici, who went plenty fast enough given the extremely testing conditions.
Mountainous, for whom it can never be soft enough, was under pressure from some way out and was never really a threat to the seven-length winner.
There may have been 11 runners, but the conditions took their toll and only three finished, with Streets Of Promise a distance back in third.
"I'm absolutely thrilled and they've both run to their best form," said Lee.
"Both jockeys (Jake Greenall and Richard Patrick) were excellent, they were given very clever rides.
"I had no idea which one would win as they had both been in good form at home, working nicely.
"I was asked this morning which one I fancied the most and because I couldn't choose I told them to do a reverse exacta!
"Goodtoknow will hopefully go up enough now to get in the Grand National, that's where I'd like to go with him."
The winner was cut to 66-1 from 100-1 for Aintree by Paddy Power.
