Yeah, I'd be very surprised to see an England declaration before lunch. I'm sure we'll just go for big biffing shots and super-aggressive cricket and see how long it lasts. If it does last until lunch then, yes, I imagine we'd put the Indians in with an unrealistic target.
Oh, and then there's the potential psychological impact of three declarations in four innings. I remember how demoralising it was to face the Aussies in their pomp, with the thought going around "we just can't get 20 of their wickets over a match".
