CSK have made a comeback in the cash-rich league after serving two-year suspension for spot-fixing.
Choosing to bowl first, the Super Kings got their first breakthrough on the ninth ball of the match as Knight Riders opener Sunil Narine was dismissed by Harbhajan Singh for 12.
The cash-rich T20 tournament returned to Chennai after a two-year ban handed to the Super Kings for illegal gambling expired.
Chennai now have two victories after they defeated defending champions Mumbai Indians in their opening match. CSK played their first match at home nearly after two years, which they won by five wickets.
The threat of more protests prompted police to step up security for the cricketers, including during their journey to the stadium from their hotel.The CSK team suffered a slight delay on its onward trip to the stadium for the match due to the disruption.
Kasi Viswananthan, Super Kings' chief executive officer, met the Chennai police commissioner on Wednesday afternoon and was advised to "reschedule" the matches in the wake of the ongoing protests in the city over the Cauvery river water issue, a long-standing dispute between Tamil Nadu and its neighbouring state Karnataka.
Earlier, After Dhoni won the toss and chose to put KKR in to bat, KKR started off on a positive note.
Unlike last match, this time CSK came together as a team and everyone tried contributing.
According to a report in Financial Express, the decision was taken by BCCI after the CSK vs KKR match at Chepauk on Friday.
KKR lost two wickets in the form of Sunil Narine (12), and Chris Lynn (22) who failed to make the most of a reprieve when Deepak Chahar grassed a hard catch off Harbhajan's bowling.
Billings, one of the two changes made by Chennai, blazed 56 off 23 balls to carry Chennai to 205-5 with a ball to spare. I somehow still feel KKR scored more than us because of all those sixes.
Cometh the hour, cometh the man: Shane Watson and Ambati Rayudu provided just the right kind of start the CSK would have visualized, raking up 75 runs in just six overs before Watson (who hit 3 fours and 3 sixes) holed out. Dhoni, as usual, took his time but the required rate was climbing all the time and with Suresh Raina struggling with his fitness at the other hand, CSK were heading for a loss.
