Junior Agogo bagged a second-half brace as Nottingham Forest beat Chesterfield to boost their promotion hopes.
After a lifeless first half, Ghanaian Agogo opened the scoring by confidently slotting past Barry Roche having been put in by Jack Lester.
Agogo doubled the lead from the spot after Roche fouled him in the area.
Aaron Downes headed home an Alex Bailey cross to set up a tense finale and David Prutton cleared a Paul Shaw volley off the line as Forest held on.
