why not just beat WI and Aus both emphatically
WI has the advantage of an extra game in hand - let them figure it out themselves 
Nah, if we are in a chase tomorrow and in a comfortable position with wickets in hand, I would prefer the guys take it till the end and achieve the target with just an over or 2 to spare, as opposed to accelerating and hurting the WI NRR. Doing so would really put severe pressure on Australia in the final encounter to not just beat us, but beat us by a good margin, provided WI beat Eng by a good margin.
i think you are reading this wrong. us playing slow and not hurting WI's NRR would be silly. if you do a quick calculation, a net runrate difference of 1.2 is not impossible to catch up. rather than worry about who comes with us to the final, the nature of this knockout means look out for yourself - it aint over till its over.
WI's net RR is on 0.2 and Australia's is 0.5, ours is 1.7
assuming a close victory tomorrow, if aussies thrash us and WI thrash england, we could find ourselves sitting out! a quick look at some of the one-sided matches in this tournament is proof that this is a real possibility.
this is a moot point if we lose tomorrow.
anyways, after seeing the SA vs SL match at Ahmedabad, I would like India to bat first. The new ball was swinging and seaming like crazy under lights. Seam more than swing actually. Munaf will be good to watch in those conditions. And there was not much dew at all till the 30th over.
