Only four teams have chased more than 400 in the fourth innings to win a Test. Opener Tamim Iqbal was unbeaten on 23 at close with Mohammad Ashraful on 16. Indian paceman Zaheer Khan had Imrul Kayes caught behind in his second over before Ishant Sharma dismissed Shahriar Nafees (21), with stand-in captain Virender Sehwag taking a low catch at gully. Nafees failed to make the most of the chance he got on five when he was dropped by Venkatsai Laxman at second slip off Zaheer.
Left-handed opener Gambhir (116) earlier became the fourth batsman to smash a century in five successive Tests as India declared their second innings at 413-8 shortly after tea. Australian Don Bradman holds the world record of making hundreds in six consecutive Tests. South African Jacques Kallis and Pakistan's Mohammad Yousuf are the others to have made centuries in five consecutive Tests.
India added 291 to their overnight total of 122-1, with Gambhir, Laxman (69 not out) and night-watchman Amit Mishra (50) the main contributors. Left-arm spinner Shakib Al Hasan finished with 7-174, the best by a Bangladeshi bowler against India in a Test. Gambhir completed his hundred in style, hoisting Shakib over long on for a six. He also hit 10 fours in his 129-ball knock. His last four centuries came against New Zealand (at Napier and Wellington) and Sri Lanka (at Ahmedabad and Kanpur) in 2009.
