India need another 100 runs with six wickets remaining after a shaky start to their chase in the second Test against Bangladesh.
The hosts were dismissed for 231 in their second innings on day three at the Shere Bangla National Stadium in Mirpur, setting India a target of 145.
A devastating spell from Mehidy Hasan (3-12) gave Bangladesh hope of levelling the series, reducing India to 45-4 at the close.
Bangladesh began the day on 7-0 but struggled early as Najmul Hossain Shanto (5) and Mominul Haque (5) fell to Ravichandran Ashwin and Mohammed Siraj respectively.
When captain Shakib Al Hasan was out to Jaydev Unadkat, Bangladesh were in trouble at 51-3, though Zakir Hasan followed up his debut Test hundred in Chattogram with another half-century, before getting out for 51.
After Zakir and Mehidy (0) had gone, Bangladesh were struggling on 113-6, though Litton Das (73) produced much-needed partnerships with Nurul Hasan (31) and Taskin Ahmed (31 not out) to make India's eventual chase more challenging.
There was an early wobble for the tourists as stand-in skipper KL Rahul (2) edged Shakib to Nurul at the start of the third over, before the wicketkeeper also stumped Cheteshwar Pujara (6) off the bowling of Mehidy.
The same duo combined to dismiss Shubman Gill (7) before Virat Kohli was Mehidy's next victim, out for just one from 22 balls after his inside edge was caught by Mominul at short leg, leaving Axar Patel (26no) and Unadkat (3no) to return on what promises to be a gripping day four.
Mehidy puts India in a spin
Having only taken 1-61 in the first innings, Mehidy came into his own in the second as he dragged his team back into the contest.
The 25-year-old claimed three big wickets to give the Tigers a fighting chance of pulling off a victory.
Axar also finds his rhythm
It was a good day for spin, with Axar also taking three wickets for India, having not managed any in the first innings.
Axar trapped both Mushfiqur Rahim and Mehidy lbw, before claiming a stumping when he outfoxed Nurul to end with figures of 3-68.
