Indian captain Virat Kohli struck his fourth double-century in four series, as the hosts took full control of their one-off Test against Bangladesh in Hyderabad.
Kohli put England to the sword before Christmas and picked up where he left off with a superb innings of 204 to break a Test record.
The 28-year-old has notched double tons against the West Indies, New Zealand, England and Bangladesh in the past seven months - surpassing Don Bradman and Rahul Dravid who went beyond 200 in three successive series.
India eventually declared at 6-687 to leave the Tigers trailing by a mammoth 646 runs at the end of Friday's second day.
Kohli began the day on 111, with India 3-356, and wasted little time in extending the stranglehold at the Rajiv Gandhi International Stadium.

The right-hander added 121 runs alongside Ajinkya Rahane in the morning session and put on a fourth-wicket stand of 222 before the latter was dismissed.
Rahane managed 11 boundaries in his knock of 82 but Mehedi Hasan Miraz caught him off the bowling of Taijul Islam in the 114th over.
Kohli kept his cool and continued to toy with Bangladesh's attack and successfully reviewed a lbw decision on 180.
The skipper managed to rack up 24 boundaries in 246 balls before he finally fell lbw to Taijul (3-156) with India well in command at 5-495.
Ravichandran Ashwin added a brisk 34 before Ravindra Jadeja and Wriddhiman Saha took the hosts to 6-620 at tea.
Saha (106no) went on to complete his century, while Jadeja was also unbeaten on 60, before a demoralised Bangladesh were forced to bat out the final 14 overs of the day.
India's declaration paid dividends when Soumya Sarkar (15) was dismissed by Umesh Yadav after a review to leave the visitors 1-41 heading into day three.
