Me thinks that its wrong to look at each and every strategic move made by India as a move against Pakistan. India aspires to be more than just a regional power and perhaps this move is a manifestation of that ambition. Also, as already pointed out it significant from energy security point of view.
I think its unlikely that India would use this base in case of conflict against Pakistan. If 'choking' Pakistan is the aim of GoI, then it would need more than just one air base to do that.
Or maybe it is just an ammunition dump or assembly shop for all the goodies flowing in from Russia.
