Winning the toss would be the key in the third cricket one-dayer between India and the West Indies to be played on Saturday.
The southern metropolis has been witness to unusually high amount of dew in the past month and that factor is bound to make batting second a difficult proposition at the MA Chidambaram stadium.
"The team winning the toss and batting first will call the shots mainly because of the dew in the evening. It has not been predictable though," said K Parthasarathy, curator of the Chepauk pitch.
"Some days it begins to fall at 6.30 pm and for the last two days it is being experienced only around 9.00 pm. Everything will depend on the day of the match."
"The team batting second will also have to put up with the slowing down of the surface which will make shotmaking difficult," Parthasarathy added.
India have an unassailable 2-0 lead in the four-match series.
