Resuming at an overnight score of 78, Tiwary cracked 128 to guide Bengal to 419 in their first innings. Profligate with the new ball initially, India pacer Mohammed Shami (2/74) got his sting back when the ball got old and ended Priyanshu Khanduri's 120-ball vigil at the crease for 52 runs.
In space of two balls, Ashoke Dinda (2/39) removed the in-form Nikhil Gangta for a cheap 24 before bad light stopped play at 39.3 overs with the group D leaders trailing by 256 runs.
Resuming the day on 306/5, Bengal made steady progress as Tiwary notched up his 24th first-class century and first of this season. Tiwary took 167 balls to get to the mark and found a fine
support in Shreevats Goswami as the duo looked in control in their 64-run partnership till the latter was trapped by Pankaj Jaiswal (3/83).
Bengal innings folded just after the lunch break as Rishi Dhawan (4/86) and Jaiswal wipped the tail but not before they crossed the 400-mark with Mohammed Shami hitting a 22-ball 26 that included two fours and two sixes.
"I'm disappointed because I could not make it bigger. We had time in our hands," Tiwary said.
In reply, Himachal were reduced to 9/1 with Dinda dismissing Prashant Chopra (6) in the third over but after that skipper Sumeet Verma (64) and Khanduri looked in control to lay a solid foundation.
Bengal bowlers struggled to get any help from the wicket as Verma and Chopra added 92 runs for the second wicket before Mukesh Kumar gave the breakthrough dismissing the Himachal captain caught-behind.
Shami looked lacklustre and got his first wicket -- Paras Dogra (7) -- in the ninth over and conceded 74 runs in his 13 overs. But Khanduri looked dogged in his approach and completed
his fifty in 107 balls with a fine support from Gangta, fresh from his consecutive centuries against Services and Goa.
The duo, however, could not consolidate as Shami trapped Khanduri before Dinda swung the match in their favour. "They were in a comfortable position at one stage but bowlers did well to fight back. I'm really happy at getting five wickets at the end of the day. We are in a good position, the first aim is to secure three points then we will see how the match pans out," Tiwary said.
He further backed Shami and said: "He struggled initially with his rhythm but happy that they fought back. We hope to get early breakthroughs in the morning session tomorrow."
