Building on their day one advantage, India reached 100 for two at lunch on the second day of the fourth Test against England here.
At the break, Cheteshwar Pujara was unbeaten on 28 runs, while Virat Kohli was batting on 25.
The duo put on 50 runs for the third wicket as India are now adrift by 146 runs in the first innings.
Starting from overnight 19 for no loss, Shikhar Dhawan (23) and KL Rahul (19) made a sedate start. The duo were watchful for any hint of lateral movement, similar to what the Indian pacers generated on the first morning of the match.
James Anderson (0-37) didn't find much movement, while Stuart Broad (2-34) did hit on a troubling length to the left-handed Dhawan whenever he pitched the ball up.
Broad struck in the fourth over of the morning, trapping Rahul lbw in the eighth over of the innings. The batsman opted for DRS, but the decision stayed in England's favour.

The pacer had another appeal against Dhawan turned down, this time for caught behind in the 14th over, and even on DRS, the batsman benefitted as the ball only clipped his thigh pad.
Bowling a lengthy first spell this morning, Broad finally got a second reward for his efforts as he continued to tease Dhawan outside the off-stump. Finally, the edge came in the 18th over, with the batsman caught behind immediately after India crossed 50.
It brought Pujara and Kohli together at the crease, and thanks to the latter, the Indian run-rate picked up once again. Kohli hit four fours during his 40-ball stay thus far, and in doing so crossed 6000 runs in Test cricket, the second-quickest Indian batsman after Sunil Gavaskar to reach the mark.
England's desperation could be seen in that they put both spinner Adil Rashid (0-5) and Moeen Ali (0-0) into the attack just before lunch. Sam Curran (0-16) had earlier toiled hard but in vain, and even Keaton Jennings (0-4) was tried for two overs.
Pujara and Kohli though settled down for what should be a lengthy Indian innings in helpful batting conditions, as the score crossed 100 at the stroke of lunch.
The Indian pacers rattled England and reduced them to 86 for six, before Sam Curran's second Test half-century helped them post 246 runs in the first innings.
England lead the five-match series 2-1, after winning the first two Tests at Birmingham and Lord's, with India pulling one back with victory in Nottingham.
