Nbd2 Nbd7 6. b3 {The cagey play continues, neither side seemingly ready to commit to castling or engineer a break on the c-file.} c5 {And so, with White turning down the chance to make a c4 pawn advance herself, Black decides to take the plunge.} 7. Bb2 cxd4 8. exd4 O-O 9. O-O a6 10. Ne5 g6 $6 {Weakening the dark squares around the king and, as every black pawn now sits on a white square, the future looks bleak for the queen's bishop.} 11. Re1 Nh5 12. c4 dxc4 13. bxc4 Ndf6 14. Qf3 {A multi-purpose move that brings the queen into play, prevents the knight on the rim from accessing the f4-square and hinders Black's queenside development.} Ng7 15. Rad1 Nf5 {Regrouping has hardly improved the situation and White soon consolidates her positional advantage.} 16. Bxf5 exf5 17. Qh3 ({Better is} 17. d5 Re8 18.
