Nc3 Nc6 6. Be3 Nf6 7. Be2 O-O 8. f4 d6 9. O-O Ng4 {Black hopes to simplify away White's attacking potential, but trades off his best defensive pieces in the process.} 10. Bxg4 Bxd4 { 10...Bxg4 loses a piece.} 11. Bxd4 Bxg4 12. Qd2 { White won't give up the a1-h8 diagonal without a fight.} 12... Be6 { This loses a tempo, since White was going to play f5 and Rf3-h3 anyway.} 13. f5 Bc4 14. Rf3 Nxd4 15. Qxd4 Ba6 16. Nd5 Rc8 17. f6 Rc4 18. Qd2 exf6 19.
