O-O-O { White hopes to gain time to use in the kingside attack by delaying or leaving out the development of the bishop to c4. If Black simply develops as normal this extra time can be very advantageous to White. } 9... d5 { This is what White's last move allows. Now there are some exchanges in the center. } 10. exd5 Nxd5 11. Nxc6 bxc6 12. Bd4 { The positional approach, offering the trade of dark-squared bishops. White can win a pawn here with 12.Nxd5 cxd5 13.Qxd5, but after 13...Qc7 the open files on the queenside give Black plenty of attacking chances. Note that 14.Qxa8 Bf5! wins the queen. After 15.Qxf8+ Kxf8. Black still has a strong attack. } 12... e5 13. Bc5 Be6 { Another typical offer of an exchange sacrifice in the Dragon. } 14. Ne4 { After 14.Bxf8 Qxf8 most experts agree that Black's attacking chances and dark square control more than make up for the slight material deficit. Note that Black already threatens ...Bh6, pinning the white queen to the king. Indeed, Dragon expert and Grandmaster Eduard Gufeld has won at least once in this fashion! } 14...
