India opener Gautam Gambhir felt a selective approach against the new ball was the key to his century against England in Mohali.
The 27-year-old overcame the early loss of opening partner Virender Sehwag to put the hosts in a strong position at the end of the opening day to the second Test.
When bad light ended play early India were on 179-1, the left-hander on 106 not out. Rahul Dravid was alongside him, unbeaten on 65.
Gambhir's fourth Test ton was his second at the PCA Stadium. He made 104 against Australia at the same venue in October.
"Every Test hundred is special to me," he told Sky Sports.
"This is a much better hundred than the one I scored against Australia because the ball was doing a little bit, and we lost 'Viru' (Sehwag) very early.
"It was important for me and Rahul to have a partnership. They were coming really really hard at us and the way we handled the fast bowling in the first session was critical.
"Initially I was telling myself to be selective. It was doing a bit so it was important to see out the new ball until lunch. I always knew that if I could get through to lunch it would get easier."
While Gambhir's innings saw him continue his fine run of form in Test cricket, Dravid's 205-ball knock came at a crucial time in the career of the former captain.
The right-hander had not scored a half-century in his previous nine innings and was under intense pressure to find some form to keep his place in the side.
"He's a great player - getting 10,000 runs in Test cricket is not a joke," Gambhir said of Dravid. "He's a legend in Indian cricket.
"We always knew he was just one innings away, that once he got a good score under his belt his confidence would go up."
