Voy Por Ustedes gave trainer Alan King and jockey Robert Thornton their second 2007 Festival success with victory in the Queen Mother Champion Chase.
The duo had combined for a win on Tuesday when My Will de Solzen took the Arkle Trophy and they were celebrating for a second time at Prestbury Park thanks to the six-year-old's lengh and a half success over Dempsey.
The 6-5 favourite Denman was a worthy winner of the Royal & Sun Alliance Chase, racing impressively up the Cheltenham hill under Ruby Walsh for a comfortable success.
Donald McCain got his first Cheltenham winner as a trainer when Cloudy Bay and jockey Richard Burton triumphed in the Fulke Walwyn Kim Muir Challenge Cup while Dr Richard Newland scored with Burntoakboy.

Cloudy Lane gave first-season trainer Donald McCain junior his first Festival
winner with his first runner when taking the Fulke Walwyn Kim Muir Challenge Cup
Handicap Chase for amateur riders.
The well-backed 15-2 favourite was well in touch on the second circuit before leading at the third-last in the hands of Richard Burton.
The seven-year-old, owned by Trevor Hemmings, came home three-quarters of a
length clear of the rest of the field.
"This little horse is the first one owner Trevor Hemmings sent me and he's done everything we've asked. I really fancied him, but I thought I was being a bit naughty fancying him as I was coming to Cheltenham with my first runner."
Winning trainer Donald McCain
1600 Coral Cup (2m 5f)

2. Powerstation (DF O'Regan) 12-1

4. Oscatello (R Johnson) 8-1
28 ran. Dist: 3, 5
Burntoakboy, ridden by Sam Jones and trained by Dr Richard Newland, put in a foot-perfect performance to beat 27 rivals and win the Coral Cup.
The fast-improving nine-year-old, who has found a new lease of life since his move to Newland's stable, was ridden superbly by Jones and they went on to win by three lengths from Irish challenger Powerstation.
But the second-biggest cheer in the winners circle was for Oliver Brady, trainer of third-placed Baron de Feypo, who took off his shirt to reveal the GAA jersey of his native county of Monaghan.
"He travelled so well in the race and he winged everything. He jumps brilliantly and was obviously very well in. I wanted a good jump at the last to seal it and got it. He's not the biggest, but he's got a big heart and keeps on galloping."
Winning jockey Sam Jones
1555: There is a lot of money going on the Nicky Henderson-trained Copsale Lad in the Coral Cup. He started the day at 10-1 but is now down to 6-1.
1515 Seasons Holidays Queen Mother Champion Chase (2m)

Voy Por Ustedes continued a good week for trainer Alan King with a well-earned win in the Queen Mother Champion Chase.
The 5-1 shot gave jockey Robert Thornton his second win of the week after his stablemate My Way de Solzen's win in the Arkle Trophy on Tuesday.
There was drama early on when the favourite Well Chief crashed out at the second fence leaving Newmill and Ashley Brook challenging for the lead.
Thornton started to challenge midway through the race and looked to be travelling well before a mistake at the second last seemed to have cost him his chance, leaving Dempsey in the lead.
But the determined six-year-old showed great determination to overhaul his rival in the final stages for a win by a length and a half with Dempsey and River City filling the other places.
"I'm just speechless. He stayed on so well but I thought he had lost it with the mistake at the second last."
Winning trainer Alan King
1505: Well Chief's owner David Johnson
"I haven't backed him. Denman has set the pace - hopefully we'll follow suit. I'd be happy to win. Maybe the time off has done him good - we'll see. If he stands up, I think he will win."
1455: Denman's co-owner Harry Findlay (who won £2m through betting on his charge to win the Royal & Sun Alliance Chase) on BBC Radio Five Live.
"It's just fantastic but the gambling's not important at times like this. Next year with My Way De Solzen and Denman you'll see the best steeplechasers for 25 years."
1435 Royal and SunAlliance Chase (3m ½f)
1. Denman (Ruby Walsh) 6-5f
2. Snowy Morning (Mick FitzGerald) 10-1
3. According to John (Tony Dobbin) 66-1
17 ran. Dist: 10, 3½
Denman justified favourtism to claim a highly impressive win in the Royal & Sun Alliance Chase.
Jockey Ruby Walsh had the 6-5 favourite at the head of affairs and jumping superbly from the start and he was rarely troubled.
Aces High joined him at the head of affairs for a while but then stumbled three fences from home leaving Denman clear at the head of the field and nobody could challenge.
He ran strongly to the line leaving owner Harry Findley £2m richer after he put a sizable bet on his charge to triumph.
"He's cruised all the way and was foot perfect. For a big horse he is very agile."
BBC Five Live commentator Luke Harvey
"He's a really good horse and we've always known he's decent."
Denman's trainer Paul Nicholls
"Denman did not look anything special in the paddock, but he did his talking on the track - and the roar from the crowd was one of sheer relief. For many shattered punters, this was the big result of the meeting so far."

1400 Ballymore Properties Novices Hurdle (2m 5f)
1. Massini's Maguire (Richard Johnson) 20-1
2. Tidal Bay (P J Brennan) 10-1
3. Catch Me (B J Geraghty) 7-1
15 ran. Dist: nk, 1½
Richard Johnson gave the Philip Hobbs stable some consolation for defeats on Tuesday for Detroit City and Fair Along by winning Wednesday's opener on Massini's Maguire.
Johnson had his mount at the head of affairs from the start and although Catch Me and Barry Geraghty challenged, he powered up the hill to claim victory.
The well-backed favourite Aran Concerto never looked comfortable and made a mistake on landing a couple of fences from home which finished his challenge.
"I knew he would stay well so I just left him to it. It's not been a good week up to now but this makes it worthwhile."
Winning jockey Richard Johnson
"Tony McCoy said the horse just didn't settle and didn't give himself a chance. He's a good horse and he didn't perform to his potential today."
Aran Concerto's trainer Noel Meade
1400: Aran Concerto and Silverburn lead the market as the day's opening race gets underway.
1355: The horses for the Ballymore Properties Novices' Hurdle have left the parade ring and are on their way to the start.
1345: Moscow Flyer, the former winner of the Queen Mother Champion Chase, who was retired after last year's race, is paraded around the paddock on his return to Cheltenham and looks in superb form.
1325: Bookmaker Freddie Williams on BBC Radio Five Live:
"We had a good day yesterday but if the favourites in the first three races win, we'll be penniless."
1300: It's another crisp and bright day at Cheltenham with the second day's racing an hour away and the excitement is building. The ground is good to soft (good in places) after a dry night.
