What I would like to see happen
India bat for 38 overs, score at a rate of 5 rpo ( irrespective of wickets lost), push the total up to 270 and declare. This will give Australia 270 runs to chase in 50 overs on a Day 5 wicket.
What is likely to happen
Australia will throw everything at their disposal at India in the first hour. If they dont make a serious enough dent ( a wicket or two), both teams will resign themselves to the draw. And we will see Australia get their over rate right for the first time in the series ( courtesy the extra work done by the spinners).
Rahul Dravid will get some valuable time in the middle and Gautam Gambhir will consolidate his claims for Man of the Series.
And the Australians will get an additional day of working on their tans.
From left field
India bat at 3-4 runs/over till tea. That pushes the score to 250-270. And then India declares. This will give Australia 30 overs to play for the draw.
And gives India the opportunity to pull the Australians down just a notch ( or two). Or the opportunity to think of the what might have beens if we get 5 odd wickets.
