BEN Davies came to Chester's rescue just when the Deva Stadium fans were settling for a frustrating draw.
The livewire midfielder (left) popped up three minutes into added time to turn home a pass from substitute Steve Brodie to give Chester their second successive home victory and their seventh point of the season.
It wasn't champagne football on another warm afternoon and stand-in skipper Paul Carden was the first to admit it. "We have to be better than that," he said.
"But there will be other games when we will play better than this and lose.'
Manager Mark Wright had planned to name the team which had beaten Tamworth in midweek, but skipper Andy Harris was ruled out with a broken hand and Shaun Carey was called up. He was subbed early in the second half as Chester struggled to break down a Forest Green defence which had conceded five goals at Hereford a few days earlier.
The Gloucestershire side is still looking for its first win, but at least they battled hard and made life difficult for Chester whose best first half chances came when defender Carl Ruffer's early header was saved by goalkeeper Steve Perrin and and when Perrin kept out a Davies shot.
Rovers were always a threat on the break through former Wolves striker Jimmi Lee-Jones who brought a fine save from Wayne Brown just before the break.
Chester were more dangerous in the second half with Danny Collins and Kevin Rapley going close, while Steve Jenkins was close to putting Rovers ahead when a Steve Jenkin shot was deflected wide.
City deserved their winner, but it was a little late for the comfort of Mark Wright.
Rovers' former Sunderland player Gary Owers was sent off after the final whistle for alleged violent conduct.
