Hello John,

>>9...dxc4 and 9...Qc7 are the most popular moves.

9... Ne4 isn't a novelty...

[Event "?"]
[Site "Paris op ch A"]
[Date "1993.??.??"]
[White "Laurain,D "]
[Black "Khaznawi,F "]
[Result "1-0"]
[ECO "A13"]
[Round "6"]

1. c4 e6 2. Nf3 Nf6 3. d4 d5 4. Nc3 Bb4 5. e3 c5 6. a3 Bxc3+ 7. bxc3 O-O 8. Bd3
Nc6 9. O-O Ne4 10. Qc2 f5 11. Ne5 Nxe5 12. dxe5 Qc7 13. f3 Ng5 14. cxd5 exd5 15.
c4 Qxe5 16. f4 Qxa1 17. Bb2 Qxf1+ 18. Kxf1 dxc4 19. Bxc4+ Ne6 20. Qb3 Re8 21. g4
Kf8 22. gxf5 Nc7 23. Qc3 Re4 24. Qxg7+ Ke8 1-0

Nevertheless more important than the question "theory?" is the "positional
sacrifice by Rybka".

Kind regards
