if the forecast is ok for the next 3 days and I was flower, I would be telling all the batters to bat as long as possible. End of the 3rd Day at least, if not to lunch on the 4th Day. I dread to think what England might score by Saturday evening - 700?. Anyway, firstly it wins the series by making the game safe and secondly India will have to survive on a deck that should be getting worse. If India bat 5 sessions to secure a draw then they'll deserve it.
