Tamim Iqbal survived a testing spell from Ishant Sharma to keep Bangladesh afloat for almost the whole session but he wasn't pardoned his one big indiscretion eight minutes before lunch and his dismissal put India ahead again.
Mohammad Ashraful and Raqibul Hasan, unlike Tamim, didn't provide much resistance, failing the early thorough examination given by Ishant and Zaheer Khan.
Like Tamim, who lacked support from his team-mates in the first half of the session, India's two best bowlers gave way to ordinary back-up bowling: Sreesanth struggled for rhythm, bowled three no-balls, and couldn't get any disconcerting movement; and Amit Mishra looked innocuous against two left-hand batsmen who were ready to step down to him and sweep.
Mohammad Ashraful started the day playing ordinary cricket: after surviving two slashes and edges in the first three overs, he drove on the up at an Ishant delivery that held its line enough to take an edge. Raqibul showed the willingness to fight, even taking a blow on the elbow, but Ishant's re-found offcutter proved to be too good for him, trapping him plumb in front.
Tamim, at the other end, was concentrating hard. Except for one loose drive in the second over, he resisted the cover drives that come naturally to him. The way he tried to open up against Sreesanth and Mishra showed the concentration had taken an extra effort. From 27 off 81 balls, when the back-up bowlers were introduced, he moved to 50 off 106, bringing up the milestone with a reverse-sweep.
But Virender Sehwag replaced Srresanth and, in his second over, Tamim went for a big booming drive when he was close to neither the line nor the length of the delivery. The outside edge was snapped up by an alert Rahul Dravid, and India were sensing victory.
