Excellent decision by captain and coach to declare so late. They learn from 1st innings they can get maximum wickets only with the new ball ( maybe till 30 overs) so, they have to give maximum over to siraj and akashdeep. Now, tomorrow they can take 2-3 wickets in first 10-15 overs of morning session. Had they bowled 30 overs today with prasidh and jaddu they most likely have gone wicketless and the ball would be too old to have any swing left. India were not batting for 600+ score they were consuming more overs for this reason. They also successfully bluffed team England in believing India is playing for a draw. Now India has more chance to win this match.
