Wasim Jaffer completed a double-century to put India in a commanding position in the second Test against Pakistan at the Eden Gardens here on Saturday.
The opener cracked a solid 202 as the hosts reached 449-4 in their first innings at lunch on the second day after resuming at 352-3. Sourav Ganguly (62) and Venkatsai Laxman (41) were batting at the interval.
Jaffer, 192 overnight, reached his second double-hundred in 24 Tests in the morning's second over, when he drove paceman Shoaib Akhtar through the covers and then steered him past gully for two fours.
He was just 10 short of his career-best 212, made against the West Indies at Antigua last year, when he edged left-arm seamer Sohail Tanvir's first delivery to wicket-keeper Kamran Akmal.
Jaffer struck 34 fours in his 274-ball knock.
Pakistan then struggled for wickets on a placid track as left-handed Ganguly and Laxman gave no chance to the rival bowlers and fielders during their unfinished 74-run stand for the fifth wicket.
Ganguly, 17 overnight, grew in confidence as the match progressed and executed some fluent shots in front of the wicket. He reached his 30th half-century when he turned part-time spinner Yasir Hameed for a four.
The left-hander, playing on his home ground, had so far struck nine fours in his 98-ball knock.
Akhtar, who passed a fitness test on Friday after suffering from a chest infection, bowled in short spells for a second successive day but failed to get a wicket.
He tested the Indian batsmen, especially Ganguly, with short-pitched deliveries. He has so far conceded 52 runs off 14 overs.
Tanvir was again punished by the batsmen as Ganguly and Laxman took four boundaries off him in an over. He has so far given away 152 in 34 overs.
India lead 1-0 in the three-Test series following their six-wicket victory in the opening match in New Delhi on Monday.
