Thankfully for Bangladesh, their partnership ended early in the session.
Pant edged the ball from Mehidy Hasan Miraj to wicket-keeper Nurul Islam, who took the catch safely to break a huge and potentially match-turning partnership of 159 runs between Pant and Iyer.
Shakib then joined the party, dismissing Axar Patel (four), Iyer and Ravichandran Ashwin (12) in quick succession to take India to 286-8.
Umesh Yadav and Jaydev Unadkat then added 14 runs each to take India’s total past 300, before Taijul and Shakib both claimed their fourth wicket of the innings to dismiss India.
