9. c3
[edit | edit source]9. c3 makes an escape square for White's bishop, so that ...Na5 or ...Nc5 no longer threatens to trade it off.
Next for Black is to develop their final minor piece and make way for castling, 9...Bc5 or 9...Be7.
9...Bc5 increases the pressure on f2. White plays 10. Nbd2 O-O 11. Bc2, the St. Petersburg variation, a threat to take twice on e4, removing Black's difficult advanced knight and winning the pawn. The old move is 11...f5, to defend the knight, but better is the surprising Dilworth variation, 11...Nxf2! 12. Rxf2 Bxf2+ 13. Kxf2 f6. Usually the trade of two minors for a rook and pawn is a bad deal, but here it works out and Black has a strong initiative with the f-file about to open.
9...Be7 is the classical defence, a more conservative developing move intending 10. Nbd2 O-O 11. Bc2 f5. Another line is 10...Nc5 11. Bc2 d4 12. Nb3, whereby Black can answer 9. c3 and 9. Nbd2, the Bronstein variation, in the same way.
