The Spireites huffed and puffed and took 86 minutes to get past Walsall, eventually claiming all three points at the Proact to bolster their promotion push.
Match-winner Sam Hird spoke to Spirieites Player after scoring the only goal of the game, explaining that the team had always hoped to capitalise on their height advantage at set pieces.
Hird said: "We'd been saying since the beginning of the game that they weren't the biggest side and we knew that we could cause problems from set plays today - we didn't cause as many as we would have liked but I did fancy myself.
"Nobody likes to blame the weather, it was a bit windy today and it was hard to play our own game today. Walsall are a footballing side as well and it was a bit of a scrappy game for the fans to watch.
"At the end of the day we went to Peterborough last week, played well but lost 1-0, today we've come away and won 1-0 and that was the main aim."
The defender also talked about the change in set play strategy that lead to his late headed winner.
"We said at half time that instead of whipping balls in we were going to start drilling it," he said." I just thought I'd come in late round the back, it fell to me and I attacked it well."
The weekend victory sets up a huge play-off tussle for the Spireites on Tuesday night when they travel to Bradford City for a re-arranged match that could go some way to determining both sides' end of season run.
Hird said: "It's going to be a great game, probably another scrappy one after seeing their pitch on TV. You know what to expect at Bradford, it's going to be tough but we're confident of going there and getting three points.
"We'll still approach it trying to play football. The pitch here at the Proact's as good as it can be but it's still not brilliant at this time of year, it never is.
"We play football but we always know when to go long and when mix it. We've got players we can bring on to change the way we play so we'll be well prepared and confident."
