India look set to make a huge total in the 1st innings of 600+ runs if Kohli can stick around and make 100+. WI really need to come out on day 2 and bowl well to keep India under 600 runs because if they get 600+ runs its all over as the WI batting hasn't been performing well in recent times so it would be tough for them. India need to bounce back from their poor test series with England which they look to be doing even though its against a weak test team.
Indians are always good at playing on home pitches but do totally opposite on other countries. India already reached 649 runs and last wicket left and Jadeja is in good form so if Shami give him some support. But the current total is already good enough for this WI to put under pressure and win this match since WI players are not good form. But as you said this huge win may give a very good confidence to Indian players to go to the next match.
India declared 649/9 and west indies lose 3 wickets for 25 runs, Mostly this match india will win with an innings if they all out west indies in low score and give them follow on. West Indies are not playing with their big players so india are having double advantage of home ground and Weak west indies players.
At the end of days play WI are 94/6 and India will force them to play follow on and make WI bat again. So chances are that if WI loose quick wickets game can get over tomorrow or max next day. It is turning out to be one sided match and also Kohli and Jadeja did made the century today.
A totally one-sided game it is and also it turned out to be pretty boring now. A quite predictable game as they already lost their 6 wickets and they will surely be followed on and with this performance by WI, I predict India will win without even batting for 2nd Innings, and it is quite possible.
Indian Cricket team's real challenge will be against Australia, though their 2 best players being out of the game, I believe Aussies will still give some tough fight. Before that in October, we will get to see some good ODI matches, South Africa Tour of Australia, 3 ODIs and 1 T20.
