The Queen's Indian, a principled fight for the e4 square. White wants to play it (e2-e4); black tries to prevent it. If that's the main criterion of this opening, it will quickly become clear that Black quickly gets a great game here.

Preventing the doubling of the c-pawns, but in this variation at least, how to play e2-e4?

Black looks fine here. The black bishop is far better than its light-squared counterpart on f1, and white remains less developed.

Closing the lid on the box. How can white untangle the kingside mess... even the slow plan with e2-e3, Bd3 hangs the g2-pawn so white would need to prepare that plan with Rg1... it's all much too slow.
