You are right that India should bat in two sessions today. Batting slowly will not be appropriate for India at all. And India should be given a target of at least 450+. If India is given a target less than this, it will be difficult for India to win.
Don't forget that India's opponent England is very experienced in the Test format. Even if India gives a target of 450+, England will try to win. So my guess is that India will not take any risk. They will want to give a target of 500+. If the batsmen can bat well, India will declare the innings with a lead of 500+. Otherwise, India will continue to bat until all the wickets are gone.
KL Rahul is batting on 46 runs and he should get his half-century soon. Shubman Gill has started the innings and is on 7 runs. India is in a good position to make runs quickly without thinking much about the wickets loss. Maybe they will play a bit normal till lunch today and they go for all hitting in the 2nd session. Batsmen to follow Rishabh Pant, Ravindra Jadeja and Washington Sundar can all hit good big time. I think India have more chances of winning his game or if the England team batted well, we can see a draw too. A lot depends on how the English batsmen take this pressure.
The Indian batsmen are in great form. India have given a huge target of 607 runs . After scoring 587 runs in the first innings, the batsmen performed well in the second innings as well. The team has scored 427 runs for the loss of 6 wickets. Shubman Gill scored 269 runs in the first innings and 161 runs in the second innings. Besides , Pant and jadeja scored 65 and 69 runs respectively.
It is very difficult to win the target of 607 runs . England will probably try to draw the match. However if England loses even one wicket today, then the chances of winning this match will decrease. England's top order batsmen will definitely have to play well to avoid defeat in the match.
The second Test, which is being played over four days, has given India and England a huge target of 608 runs. England have lost two wickets for 30 runs after batting first. We have seen the proof in the previous three innings that runs are made on this ground. I think if England cannot win, there is a possibility of a draw. Although they can bat well.
