It was a case of brotherly love and keeping it in the family at Cheltenham as Jamie Moore replaced his jockey brother Josh on Baron Alco before making all the running to win an incident-packed BetVictor Gold Cup.
Jamie had been due to ride Benatar, who like Baron Alco is trained by his father Gary.
But when he was pulled out, Jamie, who has ridden Baron Alco in most of his races, switched mounts.
After a two-length victory from Fridon in a chase where only six of the 18 starters finished, Jamie said: 'He's a horse I always ride and once Benatar was a non-runner it was always going to happen.
'Josh had a fall yesterday and is a bit sore anyway. It's worked out well for me but Josh will be delighted.
'The race went pretty smoothly. We went quite quickly over the first three fences and I was always in my comfort zone.
'His jumping has probably won him the race, there was plenty of carnage in behind. He is a tiny horse but very genuine.'
Baron Alco had some useful novice chase form, including a second place in the Brown Advisory & Merriebelle Plate Handicap Chase at the 2017 Cheltenham Festival. But a ligament injury then kept the gelding off the track for almost 600 days.
Baron Alco had made his comeback at Chepstow last month when a decent second to Charbel but, not surprisingly given his injury, Moore snr had been reluctant to run him on the unseasonably quick going and had only been persuaded to do so by the 8-1 shot's owner John Stone.
Paying tribute to his father's efforts in getting Baron Alco back into top shape, Jamie added: 'My dad is a mustard trainer. You don't need me to tell you that. Flat horses or jump horses, he can train anything.
'He'll have winners all through the winter months and has had winners at Royal Ascot.' Bryony Frost-ridden Frodon also raced prominently but, while he was eating into Baron Alco's lead, he never looked like catching him.
Favourite Mister Whitaker finished fourth but only because so many others fell by the wayside after struggling to go the pace from midrace.
Rather Be, his chief market rival, was still travelling well when brought down four out when Willie Boy fell.
King's Socks was still in with a chance when falling three out while Movewiththetimes would probably have been placed but for overjumping and coming down at the last.
Gary Moore added: 'It's massive for the yard. He is all heart and just does what you want him to do. He has got a great mind as well and if you saw him standing in the saddling box he was as solid as a rock.
'He could get an entry in what was the Caspian Caviar (Gold Cup, at Cheltenham in December) as the entries close next week. That would be the obvious thing to do.'
The BetVictor Handicap Chase was won by Philip Hobbs-trained Rock The Kasbah, in the hands of champion jockey Richard Johnson.
He has the Grand National as his long-term target, possibly via the Becher Chase at Aintree next month. But much of the credit from the race was heaped on 2015 Cheltenham Gold Cup winner Coneygree.
The injury-plagued 11-year-old was racing for only the sixth time since his glory day but he raced prominently over the marathon 3m 3f trip and carried top weight of 11st 12lb into third place, sticking on well after being headed.
Sara Bradstock, who trains Coneygree with husband Mark and said a ruin in the King George VI Chase at Kempton on Boxing Day would be considered, added: 'He is a proper competitor who wants to be out there beating people. The engine is still there.'
The day started well for trainer Paul Nicholls, who won the JCB Trial Juvenile Hurdle with Quel Destin and the mallardjewellers.com Novices' Chase with Ibis Du Rheu. Both were ridden by Harry Cobden.
Ibis Du Rheu won the Martin Pipe Conditional Jockeys Handicap Hurdle at the 2016 Cheltenham Festival and the four-mile National Hunt Chase back there in March is what Nicholls is eyeing for the his winner,.
