 Will any one plzz help me what are Black's positional inferiority and how will White take advantage of it: Sorry i can't insert the image here.

Black gave up the two bishops to white without creating any weakness in white's pawn structure. White took two extra moves to save his pawn structure. Having castled, black has a slight lead in development.  

I don't think that white has much of a positional edge in the short term.

As White, I recapture the Bishop with the b-pawn in this position. The pawns are not effectively doubled, since ...d5 has been played, White could recapture at any time and undouble his pawns. It looks more accurate to first play e3 before a3, allowing your Bishop to defend c4 from the d5 pawn.

White has some positional advantage. One being the Bishop pair. You exploit this by placing your dark-squared Bishop on an active diagonal, which Black cannot contest, because he has no counterpart to it. The other being a little more central control due to his c4-pawn. There isn't a whole lot to say about it. White needs to catch up in development, Castle Kingside (almost certainly) and decide where he would like to play--probably either in the centre or on the Queenside, and position his pieces to generate play there.

I will tell you that the only strong moves for White at this point are Bf4, Nf3 and e3.

Thnx guys i got it . I wish i can crush Carlsen sooner
