The seven-race card begins at 1.53pm, with Sisterandbrother, Yokkell and Ottoman all heading to The Roodee after being successful last time out.
The William Haggas-trained Al Maslool was a beaten odds-on favourite at Nottingham recently and will be hoping to make amends here.
Eight runners take their chances in the extended seven furlong handicap at 2.28pm.
Highland Olly kept on well to score at Beverley earlier in the month but a rise in the weights may hinder his chances.
Others to consider include the Ruth Carr-trained Woodstock and Supreme Clarets who has been knocking on the door of late.
The Hugo Palmer runner Velociraptor looks the likely victor in the seven furlong maiden at 3.10pm.
The Malpas runner made a sound start to his career at Newmarket a fortnight ago and this looks an easier assignment. The main threat looks like coming from the Sir Mark Prescott representative Sea Idol.
Seven runners race over six furlongs at 3.48pm and Tricky Tel has shown a liking to Chester and has collected a handful of wins over the last couple of seasons.
The three year old finished down the field in a twenty seven runner handicap at Ascot on a recent start, but he will find this contest more to his liking. Calico Blue and Grasmere Boy look the best of the rest.
An ultra competitive five furlongs handicap is due off at 4.23pm.
Secret Mistral made all last time out here and connections will be hoping for more of the same.
Right And Exact is out for the hat-trick after wins at Edinburgh and Thirsk respectively while Aces Wild and Rosenpur both have ability but have been poorly drawn in the race.
The penultimate affair is a 10-furlong handicap at 4.48pm.
Seven Sisters obliged at odds on at Doncaster on her last start and the three year old filly made headway to lead over a quarter of a mile out and stayed on gamely to win. Break The Bank is also worthy of consideration.
The finale at 5.33pm is another difficult puzzle to solve.
J Street has chances after wins at Southwell and Doncaster this season but a hike in the weights and being drawn in stall nine are negatives.
Stable companion Knicks could be a better betting proposition. The five year old has been running pretty consistently all season but has yet to put his head in front as of yet where it counts.
The mid-season highlight takes place at Ascot with the running of the King George VI and Queen Elizabeth Stakes (3.35pm).
This year’s renewal has all the makings of a high-quality contest, with Calandagan aiming to cement his reputation as the standout older horse following another outstanding campaign.
He is set to face a formidable field that includes Irish Derby hero Benvenuto Cellini, Japanese raider Masquerade Ball, and the classy mare Kalpana, creating the prospect of a compelling tactical battle.
