Don't worry.pitch is perfect for india.india batting decision is good.even if rain comes it will haunt australia's batting.it will be difficult to play in this pitch after rain.just 30 or 40 overs is enough to finish aus 2nd innings.400 target will be enough for india.
The current situation reminds me another MCG test (2003-04)! India was cruising along after winning the Adelaide Test. From nowhere, Australia came back after Sehwag fell to part-timer Katich on 195 and we lost the match.
