THE Blues slumped to a second successive League Two home defeat this afternoon.
Bobby Williamson’s men paid the price for failing to take their chances before the break as second-half strikes from Lee Thorpe and Sammy Moore eased the pressure on Bees boss Terry Butcher.
Brentford, reeling after a three-match losing run, also had plenty of opportunities in a first half to savour.
John Danby produced a double save from Thorpe and Glenn Poole before Poole rattled the bar with a 30-yard drive.
Chester twice went close to breaking the deadlock through Simon Yeo, who saw an effort deflect on to the post before being denied by Simon Brown.
Yeo’s strike partner John Murphy should also have done better after being picked out by star man Mark Hughes, but he could only head straight at keeper Brown.
Thorpe was not as wasteful eight minutes after the restart as he swept in from close range after Moore’s corner was not cleared.
And it was Moore who sealed victory for the Bees a minute from time by slotting past Danby.
