A steady start by City saw near total domination of possession for the opening minutes and it was over 5 mins before Martyn Margetson touched the ball.
Chesterfield came more into it and in fairness created several chances and Martyn Margetson was in excellent form and was my man of the match for City.
The Bluebirds were a class above though and the quality showed through when Graham Kavanagh scored direct from a free kick, his first goal since his FA Cup free kick against Tranmere at Prenton Park last November.
Alan Mahon was tripped on the edge of the box and Kav placed a perfect free kick past former City loan keeper Carl Muggleton (in his 80's style tight shorts).
Chesterfield tried hard but City doubled the lead when the entertainer, Gareth Ainsworth (worth the entrance money on his own) crossed low and Earnie bravely dived it. Muggleton saved the header but Thorne the poacher was on hand to fire in the rebound.
From then it was game over, City were at ease and when Chesterfield did attack anything that beat the back line was comfortably handled by Margetson. Chesterfield's best chances flew high and wide.
The icing on the cake came in the last 10 mins when Thorne turned in a low cross to give a fair balance between quality and quantity.
So we have 5 games to go. Crewe are 1 point ahead, the least we have to do is match their next 4 results to make it a winner takes all finale at Gresty Rd on May 3rd. It could change in midweek though. Crewe play Bristol City, the only other real threat for automatic promotion on Tuesday. A draw must be the best outcome for City but we have to win at Peterborough on Wednesday.
Well done to Cardiff today, following last Tuesday at Wycombe we have played two on the road, scoring 7 and conceding none. The games come thick and fast, Peterborough on Wednesday, home to Colchester on Saturday, away at Bristol City next Tuesday. There are clubs in the Nationwide league with nothing to play for, mid table obscurity assured, not for us, we are in the thick of a promotion battle and it's awesome
