Qxd4 { A rare sideline. Playable, and a nice way to avoid theory. } 5... e6 6. Nf3 Nc6 7. Qe4 f5! { But Black was booked up! This is the best way to ensure that Black does not end up cramped, as it neutralizes White's threats on the h7-square after Black castles. } 8. Qe2 Be7 9. g3 O-O 10. Bg2 Qc7 11. O-O b5 { Energetic play. Maybe Black does not have compensation, but he has room for the pieces to breathe, at least. } 12. Qxb5 a5 13. Re1?! (13. Qe2! Ba6 14. c4 Rfb8 15. b3 a4 16. Qd2! axb3 17. axb3 { is good for White, as Black has to worry about the d5-knight and thus cannot capture on b3. }) 13... Ba6 { Now, Black controls the c4-square, and accordingly White's queenside remains underdeveloped. } 14. Qa4 Rab8 15. Nbd2 Bd3 16. Qd1 f4 17. g4 Bg6 18. a3 Qa7 19. c4?? { White did not ask what the purpose behind Black's last move was. } 19... Ne3! { And Black is happy to show the grandmaster! } 20. fxe3 fxe3 21. Kh1 { Any knight move allowed ... e3-e2+ winning the queen. } 21... exd2 22. Qxd2 { Black has regained the piece, opened more lines, and is now ready to crash through before White even connects his rooks. } 22... a4 23. b4 axb3 24. Bb2 Na5 25. Rac1 Rfc8 26. Bd4 Bc5 27. Bxc5 Rxc5 28. Nh4 Rxc4 29. Nxg6 hxg6 30. Be4 Qd4 31. Qxa5 Rxc1 { 0-1 Black wins. } 0-1
