Jaffer brought up his hundred with a boundary through mid-wicket

Wasim Jaffer bounced back from a pair in the opening Test with a century as India totally dominated the opening day against Bangladesh in Dhaka.

Put in by home skipper Habibul Bashar, they reached 326-0 despite Jaffer (138) and opening partner Dinesh Karthik (82) both having to retire because of cramp.

Skipper Rahul Dravid took over and was 88 not out at the close, with Sachin Tendulkar unbeaten on nine.

India added 151 in the final session as the Bangladesh attack tired.

Both sides made changes following the drawn first Test in Chittagong.

Bangladesh brought in Syed Rasel and Mohammed Sharif to replace Shahadat Hossain and Enamul Haque Jr, while India gave a debut to teenage pace bowler Ishant Sharma.

The Tigers could wasted an early opportunity for a breakthrough when Karthik, on 10, edged a ball from left-arm seamer Rasel to second slip, where Saqibul Hasan failed to hold the chance.

Jaffer also had a let-off in the first over after lunch, when spinner Mohammad Rafique was unable to hang onto a waist-high return catch.

Karthik made the most of a let-off early in his innings

Those were mistakes the hosts could ill afford on a pitch offering nothing to their bowlers.

Jaffer and Karthik accelerated during the afternoon, although TV replays suggested the latter was fortunate to escape on 74 when keeper Khaled Mashud confidently appealed for a catch off Sharif's medium pace.

After that both looked well set for centuries but Karthik failed to re-emerge following tea and it was left to Jaffer to make his way to three figures off 185 balls with an elegant flick for four off Rafique.

The 29-year-old celebrated with two further boundaries in Rafique's next over but the stamina-sapping conditions eventually took a toll and with the total on 281-0, he was unable to continue.

It did not disturb India's momentum as Dravid batted fluently against spin and seam alike, collecting a six and 11 fours.

Paceman Mashrafe Mortaza shook up Tendulkar with a couple of well-directed bouncers but India had the final word as Dravid cut him square for four in the last over of the day.

Afterwards, Bangladesh coach Dav Whatmore admitted they had made a big error at the toss.

"We misread the wicket," he said. "We were taken in by the overcast conditions and believed the track would do a lot more and fetch us some quick wickets.

"It was not my decision alone to field first. It was a decision taken jointly by the captain, vice-captain, the selectors and me.

"But we also hope to bat well because the wicket is unlikely to change much so soon."

Jaffer, meanwhile, was relieved after his failures in the opening Test.

"I was obviously under some pressure after Chittagong and was very determined to come good," he said.
