Goals in each half from Tom Whelan and Adi Yussuf gave the Spireites all three points at The Hive.
It was a dominant performance and a perfect way to bounce back after two straight defeats.
Town moved back into the top half of the National League into 11th and are just five points off the play-offs with games in hand.

. Grant Smith 7
Called into action once in the first half after a defensive mix-up but other than that it was a quiet afternoon for the stopper. He was assured in the bits he did have to do. Photo: Dean Atkins
. George Carline 7
Bombed forward in the first half and saw a lot of the ball. Played a good part in Town's opener. Photo: Dean Atkins
. Fraser Kerr 8
Excellent. A surprise inclusion given his injury in midweek. Stepped out with the ball, pinched possession back and was strong in the tackle. Photo: Tina Jenner
. Haydn Hollis 7
Slotted back into the line-up to replace the injured Gunning. Solid. Leader. Photo: Dean Atkins
