Dhoni produced a stunning counter-attacking knock to notch up his maiden double hundred, his sixth Test century overall, while Kohli recorded his fourth in longer format as the hosts reached a commanding 515 for eight at close, on an eventful third day's play.
The Indian captain set the M A Chidambaram stadium ablaze with his amazing strokeplay as he smashed 22 boundaries and five sixes during his 243-ball assault much to the delight of a sizeable Sunday crowd which cheered the Indians as they went about consolidating their position in the match.
The Indians found the going a little tough in the pre-lunch session as the runs dried up but the second new ball ball saw the game slipping away from the Australians as both Dhoni and Kohli attacked the bowlers with an array of shots on both sides of the wicket.
Kohli paid the price for a lapse in concentration as he tried to lift a dlivery from Nathan Lyon over mid-on but could not get the desired elevation and Mitchell Starc latched on to a good catch. Kohli clobbered 15 boundaries and a six during his 206-ball knock.
