 After 9.Qd5 0-0 White has no apparent attacking prospects and move 9.Qd5 is
therefore suspicious. I would think about 9.h3 instead, as now 9...0-0 goes into
10.Qd2 with tactical trouble for Black.

 Yet (9.h3) Black has the more solid plan 9...Qe7 with idea of castling long and
when possible make f6 followed by Nf7.

 Observe that the main reason to think that White has the upper hand is that he
has the bishop pair and dark squares are a bit weak in Black's position. But
those squares may be adequately protected by the formation d6-e7-f5. Then White
should think on pawn advances to open the position, but those advances ruptures
could be risky because his pawn structure is defective.

 For these reasons I wonder if we must talk about any positional advantage for
White in the discussed position. In my view the move 3.Nf3 is no better than the
normal 3.d4.  The main reason -IMHO- for criticizing the exchange 3...Bxc3 is
that Black condemns itself to a purely defensive game.
