I would play 2. ...e6 instead. White is weakening the e1-h4 diagonal, and it's nice to be ready to take advantage of it if the opportunity arises.
Besides, Black usually develops the queen's knight to d7 in d4 openings, and when it does come to c6, the c-pawn is normally on c5, not c7.
is ther a better way to play tghis fore black?
