England may declare and have a brief bowl, Tests get called off at the final hour do they not if the captains agree? Really can't see India getting 270 off 1.5 sessions let alone whatever they might have to get if/when England decide enough is enough.
Sehwag might offer India a theoretical chance of winning, but I can't see a slog lasting long enough. Sides chasing mammoth totals in very short periods of time generally call the chase off after losing a few wickets anyway, England have had a few like that in recent years if I'm not mistaken.
India either aren't up to scratch or their pitches have made life harder for them, or a bit of both. Some of the England players have played well, the bowlers have done well, but India should have made life a lot lot harder than it proved. Had this been England you could have seen it, but in India..........!?!??!
