Second Test, Chittagong, day one (stumps)
India 334-2 v Bangladesh
Gambhir's stroke-filled century was the first of his Test career
Gautam Gambhir and Rahul Dravid hit a century apiece as India gained a strong position after the first day of the second Test against Bangladesh.
The hosts endured another woeful day as India racked up 334-2 with Gambhir hitting 139 and Dravid 145 not out.
They put on 259 for the second wicket in 68 overs as Bangladesh's inexperienced bowling attack wilted.
Sachin Tendulkar, after a double-ton in the first Test, clubbed three fours in an over to be 36 not out at stumps.
Tendulkar will now facy his chances of scoring a world record 35th Test century on Saturday.
India, leading the two-Test series 1-0, won the toss at Chittagong's MA Aziz Stadium and elected to bat first.

But before he was settled, the dashing opener then chased a wide one from Mashrafe Mortaza, Habibul Bashar taking the catch in the slips.
Bangladesh's promising start, with India 14-1 in the fifth over, proved to be a red herring as Gambhir and Dravid booked in for lengthy stays at the crease.
The limitations in the hosts' bowling were quickly
