I have a theoretical articel about this line. Shredder analysed some critical positions. One example: [Event "?"] [Site "?"] [Date "2003.09.15"] [Round "?"] [White "?"] [Black "?"] [Result "*"] [PlyCount "30"] [EventDate "2003.09.15"] 1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nd7 5. Ng5 Ngf6 6. Bd3 e6 7. N1f3 h6 8. Nxe6 fxe6 9. Bg6+ Ke7 10. O-O Qc7 11. Re1 Kd8 12. c4 Bb4 13. Bd2 Bxd2 14. Qxd2 Nf8 15. Bc2 Bd7 * Shredder 7.04 likes to play a4-a5-a6 here for a long time.
