After four day-night Test matches at the Adelaide Oval, the behaviour of the pink ball still remains a mystery. It is supposed to swing and seam under the floodlights, but as Pakistan discovered last year, it is no certainty.

Back in 2017, England's James Anderson bowled around the wicket to right handers to control the extent of his swing. Such are the uncertainties that it is difficult to plan precisely for a day-night encounter. India captain Virat Kohli was wary of the pink ball challenges and accepted the fact that his team will need to react to different situations to the best of their abilities.
