Chesterfield manager Paul Cook hailed his side as they capitalised on Scunthorpe United's draw on Monday night to move top of Sky Bet League 2 following a 2-0 win at York City.
The Spireites made the best possible start and took the lead after two minutes through Eoin Doyle before Gary Roberts doubled the lead six minutes before the interval.
Cook is refusing to get carried away with his side's position and insists his side are focusing on one game at a time.
"We started well like we did at Northampton and Eoin Doyle's goal was top draw," he said. "We looked bright and the game got a bit easy for us to be honest as we did get a bit sloppy and make a few mistakes.
"You've got to give the lads credit for two tough fixtures and to get two wins because we're playing on heavy pitches at the moment. To come away from the disappointment of Southend and Rochdale, I think the lads have responded magnificently.
"We're down to 18 games now and all we want to do is gain promotion if it's possible. We've a good group of lads here who work very hard and tonight they deserve a lot of plaudits. It's another game gone and three more points to where we want to be. There's nothing won or nothing lost, there's a long way to go."
York boss Nigel Worthington admitted his side were second best all over the park.
The Minstermen never recovered from going one goal down after two minutes with Lanre Oyebanjo's first-half effort the closest they came to reducing the deficit.
Worthington believes his team were far from their best and their sloppy start ended up costing them dearly.
"After two minutes we go a goal down, not through good play by them, and it puts us on the back foot from the start," he admitted. "Following the second goal we were all over the park. There was a lack of life and brightness and that's unusual from us.
"The second goal was our corner and they score. That's not supposed to happen in football, but if you're not on the front foot then you pay the price. At two goals down you're not out of it but we found it difficult to get a goal.
"The game on Saturday we performed but it was a disappointing result that probably flattered Hartlepool. You've got to be ready for every game in any league.
"If you start slow, like we did here, it's like pushing water uphill and in the end it overpowers you. We were second in every challenge and that's far from a winning recipe."
