Re: 1st test...Pak Vs India at Mohali
Given the weather and bad light etc, I don't think we can count on more than 2 more days of play, if that.
Scenario 1: Indian batsmen go too defensive or Pakistan bowlers come up with a great performance - either case, India will get another 200 runs for a total of 380, leading by 60 runs - Pakistan can simply play out the other 1 day for a draw.
Scenario 2: Indian batsmen play aggressive and pile up 300 runs on day 3 for a lead of about 175. Indian bowlers then have to get the Pakistan 2nd innings wrapped up in a day - with very little pressure to score, Pakistan certainly can bat to a draw for a day
Scenario 3: Indian batsmen play extreme aggression and score an additional 350 runs by tea time! Then there's a chance of a decision since Indian bowlers will have about 230 to bowl to and there will some pressure on the batsmen - one or 2 early wickets and who knows!
Senario 4: Something crazy happens, Indian batting collapses for an addition of 100 more - it still doesn't give sufficient lead to pakistani batsmen to play an aggressive 2nd innings and so draw is the fate
All said, draw is the likely outcome, because of so much loss of play time. If the bulk of 3 remaining days remain available for play, then a couple of centuries (or close) from India will be required to win.
Pakistanis will be praying for rain and louds; Indians will be praying for nice weather, Sehwag charm to hold and Tendulkar's elbow
