Btw, yesterday I found this game in my database:
[Event "XIV It"]
[Site "Pamplona ESP"]
[Date "2004.12.23"]
[Round "2"]
[White "Naiditsch, A."]
[Black "Mamedyarov, S."]
[Result "1/2-1/2"]
[ECO "C80"]
[WhiteElo "2611"]
[BlackElo "2660"]
[PlyCount "56"]
[EventDate "2004.12.22"]
[EventType "tourn"]
[EventRounds "7"]
[EventCountry "ESP"]
[EventCategory "16"]
1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Nxe4 6. d4 b5 7. Bb3 d5 8. dxe5
Be6 9. Nbd2 Nc5 10. c3 d4 11. Ng5 dxc3 12. Nxe6 fxe6 13. bxc3 Qd3 14. Bc2 Qxc3
15. Nb3 Rd8 16. Bd2 Qxe5 17. Re1 Qd5 18. Qg4 Nd4 19. Nxc5 Bxc5 20. Qxg7 Rf8 21.
Bxh7 Rd7 22. Qg6+ Kd8 23. Bh6 Nf3+ 24. gxf3 Qxf3 25. Qg5+ Kc8 26. Qxc5 Qg4+ 27.
Kh1 Qf3+ 28. Kg1 Qg4+ 1/2-1/2
15...Rd8 16.Bd2 Qxe5 17.Re1 is just a transposition, so 15...Qxe5 can not be
regarded as "Novelty".
The new move was 17...Qf6 instead of 17...Qd5.
