The 2nd test affected by rain was heading towards a draw but India wanted to do something different and get a result. India did tried to have a large score in short time and they did scored quick but also lost wickets. Now they'd be hoping to all out Bangladesh in a short total and chase the target quickly. All Bangladesh had to do tomorrow is to hold onto the wicket. If they lost all their wicket before the last session, India would try to chase it provided rain don't affect tomorrow.
In the genre of Test cricket matches, India is a super team and Bangladesh has almost no chance to win in any match though few matches they may win by the favor of luck and abandon a match or draw a match. If it is a draw match then that will be the loss of as they could win easily if there is no issue.
