India still have the upper hand in the match if they are able to take quick wickets on third day in the morning. Usually when such a big partnership is broken, the rest of the teams get out cheaply. India would be hoping that NewZealand does not take lead in the first innings.
You are expecting 500 runs. This is a huge run. It is unthinkable that a team like Bangladesh will score this run against Pakistan. If Bangladesh can play well in the first session tomorrow, and the liton-mushfik pair is not out then I think Bangladesh will be able to collect about 450. However, if this partnership will be broken at the beginning of the first session, then Bangladesh will not be able to collect more than 370-380. The new batsmen will be out quickly.
I am saying 500 runs for Bangladesh because this is their only chance. They won't be able to score big in the 2nd innings and if Bangladesh score under 350 runs, then Pakistan can still win it.
