England took a lead of over 310 runs but after taking two early wickets from India, England were unable to take any wickets from India for a long 54 overs. England scored 669 runs due to the batting pitch but India scored a comparatively low 358 runs in the first innings. That is why India is currently under pressure for runs. India will have to bat for the whole day tomorrow, so if India's batting fails for any reason, then India's defeat will be inevitable. At the moment, the playing conditions in India are very good, so they will remain unbeaten today and tomorrow India will get a chance to bat for a full day.
I would still like to speak for England. It may be possible for India to draw the match but it is absolutely impossible for India to win now. The chances of India winning from this situation of the match are less than 0.001%. But they can turn the match into a draw if they want. But I think the match will not be drawn, rather England will win. Because it will not be possible for India to bat the whole day tomorrow. Maybe they will be able to play maximum 2 sessions, but setting a big target is very difficult for them now. Only 1 session will be enough for England to meet that target. Now it is easy for India to lose the series and draw or lose the fourth match. Keeping the dream of winning the series alive is very difficult now.
India still have one more day left and are 137 runs behind, so they will not want to give England a target. They will want to bat defensively and get through the day. However, if India are all out, then if the target is very small, then England will take a chance to win, but in that case I don't think India will give that chance. Since the wicket conditions are batting-friendly, India will decide to bat in all three sessions today. The first session of the fifth day is 137 runs behind, and it will take two more sessions to make up for that run. No team will want to take risks with these two sessions, so it is likely that this Test will be a hundred percent draw.
