There's a children's rhyme which goes:

Piggy on the railway,
Picking up stones,
Along came an engine
And broke poor Piggy's bones.

"Oh" said Piggy, "That's not fair"
"Oh" said the Engine, "I don't care"

The Indian team finds itself in a similar situation. After an insipid performance in the opening game against Pakistan, India faced a must win game against Australia. The bowlers performed quite well, except when Michael Clarke showed why he must be in the test team ahead of jokers like Elliott. Getting 175 in 32 overs (or whatever the Duckworth-Lewis adjusted target would be) would definitely not be a walk in the park, but India had given themselves a chance. However, the rain came down and this effectively mean that India would pray for Pakistan thulping Australia such that Australia's net-runrate drops below -2.0 (which is what India's is currently). Assuming that the rainy conditions persist and the game is a 35-a-side one, this'd require Pakistan to bat first and make say 200 and Australia making less than 130. Alternatively if Australia made first and made 200, Pakistan would need to get the runs in 26 overs.

Why would Pakistan do India a favour after what happened at the Asia Cup? Yet, when Pakistan fails to ensure that Australia doesn't make it to the final, Indians will keep harping on the fact that there was a conspiracy afoot to keep India out and gain valuable psychological points before the two teams clash in the ICC Champions Trophy. As if Pakistan didn't have enough of a psychological edge already - they've now beaten India twice in a row. Pakistan really dont care, even if what they do isnt fair. That is why India is the piggy and Pakistan is the engine.
