The Super Kings were steered to a win again by Aussie opener Mathew Hayden who remained unbeaten on 70 off 49 balls, with six fours and three sixes, along with captain M S Dhoni who was not out on 43 off 27 balls, with three fours and two sixes. The unbeaten stand between Dhoni and Hayden was worth 86 runs off 58 balls.
Chasing an easy target of 148 in 20 overs, the Super Kings were helped along by the two South paws former India stumper Parthiv Patel and the in form Aussie Mathew Hayden who was the man of the match in the last game here.
The Riders hopes of forcing an early breakthrough from their strike bowler Ishant Sharma, the new pace sensation in team India, did not come off as he conceded eight runs in his first spell of two overs and Ashoke Dinda too failed to achieve it.
And as David Hussey came on to bowl spin at the pavilion end, Hayden hoisted him over long on and the Super Kings were 54 without any wicket in 6.4 overs, Patel on 19 and Hayden on 25.
Hayden raced to 33 off 23 balls with two sixes, both over long on. The Kings posted the best opening stand of 64 for in the IPL matches so far. They emulated the 61 run stand between Ganguly and McCullum at Kolkata.
But needing 82 from 71 balls, the Super Kings lost their first wicket when Parthiv Patel pulling medium pacer Ajit Agarkar was caught by Ishant Sharma on the fence for 21 off 27 balls, with three fours.
The wicket fell off in the second ball of the ninth over of the Kings innings.
Skipper M S Dhoni promoted himself up the order to keep the scoring momentum up.
The Kolkata Knight Riders had their cheer leader in Bollywood star Juhi Chawla, to try and turn the heat on the Super Kings. After the first 10 overs the Chennai team required 70 runs from 57 balls to win. Knight Riders captain Sourav Ganguly placed an attacking off side field for Dhoni. Left arm spiner Murali Karthik came on at the Northern end in the 12th over as the Super Kings needed 63 runs from 54 balls.
Dhoni drove Murali to the fence and then ran a single. The Super Kings were 90 for one in 12 overs and had a battle on their hands.
Dhoni posted the 100 of the innings for Super Kings with a big hit over long on for a six off Karthik. The Super Kings needed 48 off 42 balls. The 100 came in 18.2 overs.
Karthik conceded 11 runs in the 14th over. Hayden completed his 50 in 39 balls, with five fours and two sixes. Hayden and Dhoni also posted a 50 stand off 39 balls when the latter hit two fours in the 15th over.
Five overs remaining, the Super Kings needed 18 runs from 28 balls. Hayden, who is to return back to Australia after the Super Kings next match, moved on as the home team needed a mere nine from 24 balls at 2.3 runs an over. There were 12 fours and three sixes in the Super Kings innings at that stage.
Needing four from 21 balls, Dhoni stole a single off Murali Karthik. On 146 for one, Dhoni finised the match pulling the left arm spinner over long on for a huge six as the full house cheered wildly.
While the Kolkata Knight Riders suffered their first defeat, Chennai Super Kings registered their third win on the trot to remain unbeaten. They have eight points from three matches and take on Delhi Dare Devils in their next match here on May two.
