Bd3 Bb4 7. O-O O-O 8. Qc2 Bd6 {Black plans to challenge the White center by playing 8...Bd6, dxc4 and e5. However, a better move order was to start with 8...dxc4. As played White is able to give support to his c-pawn.} 9. b3 {White plans on answering 9...bxc4 with 10. bxc4. Thus lending support to his central pawns. While, at the same time allowing both his bishops to aim at the Black kingside.} 9... dxc4 10. bxc4 e5 11. Bb2 Re8 12. Ne4 {White offers Black an exchange on e4. Which will remove an important defender from the Black kingside.} 12... Nxe4 13. Bxe4 h6 14. Rad1 exd4 {A mistake which opens up the position for the White attack. 14.. .Qe7 Trying to keep the position closed should be preferred.} 15. Bh7+ Kh8 16.
