[edit | edit source]

Black prepares to fianchetto the queen's bishop.

White's best move is 3. d4 which continues 3...cxd4 4. Nxd4 Bb7.

Once fianchettoed, Black must be mindful of the danger to their weak light squares. They may be exploited by a well-timed Bb5 or Nb5, especially should Black play ...d6. e.g. 5. Nc3 Nc6 6. Be3 Nxd4 7. Bxd4 d6??, White can win a queen with 8. Bb5+! (see diagram).
