Kohli leads India's record-setting day
Virat Kohli struck his fourth double century as India declared on 6-687 and demoralised Bangladesh further by taking a wicket on a record-filled day two of their sole Test.
Bangladesh reached 1-41 in 14 overs, losing Soumya Sarkar to an edge on 15 two overs before stumps on Friday.
Bangladesh trail by 646 runs, with Tamim Iqbal on 24, and Mominul Haque on 1.
Kohli, resuming from 111 overnight, scored 204 from 246 deliveries, and hit 24 fours. He became the first batsman in cricket history to post double hundreds in four consecutive Test series.
He scored 200 against West Indies in Antigua, 211 against New Zealand in Indore, and 235 against England in Mumbai, all last year. He surpassed Donald Bradman and Rahul Dravid, who achieved double hundreds in three successive series.
He was finally dismissed in the 126th over, as Taijul Islam (3-156) trapped him lbw.
"I have seen him on television so many times, but this was a different experience bowling to him in a Test. Obviously, I got to learn a lot," teenage Bangladesh offspinner Mehedi Hasan Miraz said.
"The pitch is quite flat but the odd ball was spinning, and they were uncomfortable against those deliveries. We have scored nearly 600 in New Zealand, so we need to believe."
India resumed at 3-356 and shortly after lunch registered the highest innings at the Rajiv Gandhi International Stadium, beating their own 503 against Australia in 2013.
In passing 600 in the 147th over, India became the first team to record 600-plus totals in three successive innings after scoring 631 and 7-759 declared against England in December.
After tea, Wriddhiman Saha (106 not out) and Ravindra Jadeja (60 not out) looked for quick runs. They put on 118 for the seventh wicket, and India declared when Saha reached his second Test hundred.
Saha, who survived a stumping attempt early on as wicketkeeper Mushfiqur Rahim fumbled, got to his hundred in 153 balls.
"Virat always backs everybody and tells you to play your natural game," Saha said. "That's why I tried playing that shot (the stumping chance). But Virat said that it's not a problem, if you again get a chance, hit it."
