India speedster Mohammed Shami said altering length to keep the batsmen guessing would be key when India take on Bangladesh in their maiden Pink-ball Test, starting from Friday in Kolkata. Shami, who has been in terrific form, returned with the figures of 3/27 and 4/31 in the first Test at Indore to achieve his career-best ranking, said he intends on keeping things simple for the historic Test.

"What one thing bowlers should do is keep an eye on the wicket and how is it behaving, so what I do is as the pitch gets slower I keep pushing myself and when I notice that the batsman is uncomfortable I go over the top... so the length has to keep changing," Shami said on Nerolac Cricket Live on Star Sports.
