Karun Nair turned his maiden Test century into a triple as India earned a 282-run first innings lead over England, on day four of the fifth Test.
Click play on the video above to see the best of the day four action as Nair ran the tourists ragged, reaching 303no - India declaring on 759-7, their highest Test score, the instant he reached the milestone.
The hosts began the day on 391-4, trailing by 86, and motored on before Nair guided the ball to the third man boundary to bring up his first hundred in Test cricket.
There was another first in the next over as Liam Dawson pinned Murali Vijay (29) plumb in front to claim his first Test wicket.
Nair moved past 150 in the afternoon session as Ravichandran Ashwin went to his 10th Test fifty and Keaton Jennings was possibly England's most dangerous bowler, the opener bowling four overs at the end of the session.
He looked to have Ashwin (54no) lbw, only for the Indian to review and ball-tracker to show the ball was sliding down leg - much to England's disbelief.
Ravindra Jadeja smashed a quick fifty but the evening session was all about Nair, who reached his triple century when he cut Adil Rashid past Alastair Cook for four.
Cook and fellow opener Keaton Jennings then safely negotiated five overs before stumps, which arrived with England on 12-0 - 270 runs behind.
