Insider knowledge helped Cheltenham see off League Two basement club Barnet.
Substitute Jeff Goulding scored the game's only goal 10 minutes from time but assistant manager Neil Howarth admitted it was former Barnet midfielder Sam Deering who helped secure the points.
The struggling visitors were awarded a penalty for handball midway through the second half but Robins keeper Scott Brown went the right way and palmed away Mark Byrne's spot kick.
"It was an excellent save [from the penalty] and the kid took it well," Howarth admitted. "Sam Deering in the dugout knows where he normally puts them and we managed to get a message out. It was a good save.
"I couldn't see if it was handball or not, it was one of those where I would be certain it wasn't a deliberate handball. I thought we had one at the other end that the linesman gave but the ref overruled.
"It was a tough game, coming off the back of two defeats and two poor performances on our behalf. Being back at home and playing a team at the bottom of the league is a tough ask when your confidence levels can be a little bit low.
"I thought we did all the pressing for the majority of the game. We just didn't test the keeper enough and couldn't get the goals we wanted to make the game safe. Jeff came on and scored a great goal and when that went in I felt we could go on and win it.
Barnet player-coach Edgar Davids admitted he was disappointed by the result.
"We have to take the defeat on the chin and try and play better next time," he said. "We have played against a top side and you only have to slide a little bit and you can see why they are a good side.
"You can see positives but you also have to see your own mistakes and have to work on them because at the end of the day they are getting a bit annoying."
