	Check GM Petr Kiriakovs games. He has played this line for 15 years almost. I call this 'The Kiriakov variation'.

	I played 3...a6 a few times in corres chess tournaments around 2000 and found it to be pretty reliable, drawing most. Here's the one I won, against my arch-rival for the Midlands championship, which gave me a lot of pleasure at the time and which (I hope) is still relevant to the present discussion: [Event "P C Gibbs 1999 corres"] [Site "?"] [Date "1999.??.??"] [Round "?"] [White "McLaughlin, Keith W"] [Black "Adams, Phil"] [Result "0-1"] [ECO "C07"] [PlyCount "102"] [EventDate "1999.??.??"] [EventType "tourn (corr)"] 1. e4 e6 2. d4 d5 3. Nd2 a6 4. Ngf3 c5 5. dxc5 Bxc5 6. Bd3 Nf6 7. O-O Nc6 8. Qe2 Qc7 9. a3 Bd7!? (I remember I did a lot of analysis on this.) 10. exd5 Nxd5 11. Ne4 Be7 12. Rd1 Rd8 13. Ng3 Nf4 14. Bxf4 Qxf4 15. Qe4 Qxe4 16. Bxe4 g6 17. Rd2 Bf6 18. Rad1 Ke7 19. Rd3 Bg7 20. b3 h6 21. Ne2 Bb2 22. Rb1 Bg7 23. Rbd1 Bc8 24. Rxd8 Rxd8 25. Rxd8 Nxd8 26. Nd2 f5 27. Bf3 e5 28. Bd5 Kd6 29. c4 Be6 30. Bxe6 Nxe6 31. b4 e4 32. g3 Bb2 33. Nb1 Ke5 34. a4 Nd4 35. Nf4 Nf3+ 36. Kg2 Kd4 37. c5 Ne5 38. Ne6+ Kc4 39. b5 axb5 40. axb5 Kxb5 41. Nd8 Nf3 42. Nxb7 Kc6 43. Na5+ Kxc5 44. Nb3+ Kb4 45. N3d2 Bc1 46. Nxf3 exf3+ 47. Kxf3 Kb3 48. g4 Kb2 49. gxf5 gxf5 50. Kg3 Kxb1 51. f4 Kc2 0-1 Round about the time of this game I remember being inspired by an article of Daniel King's about how the queenside pawn majority was over-valued in most theory books and how modern praxis was showing how useful Black's beautiful 4-3 kingside majority could be.

	Oh no not a ?. Not even ?! really. Both Pedersen and Psahkis simply seems to feel that 6 .. Nf6 allows white a bit more play than 6 .. Ne7. The knight does tilt at e5/f4 quite usefully from g6 after all. The main line seems to be 6 .. Nc6 7 o-o Nf6 8 Qe2 (a3!?) Qc7 etc. Pedersen gives Kotronias - Del Rio, 2003 as slightly better there. Really though neither book gives anything appraoching conclusive grounds. So if you've looked at 6.. Nf6 and prefer it then I'd play it btw Pedersen also seems to think that 6.. c4 and 8.. b5 is OK. No recent games mind and I don't know if it's ever really been probed in depth with a modern computer. So probably worth some independent work

	Thanks for these. Does anyone know what the problem (if there is one!) with 5 dc Bc5 6 Bd3 Nf6!? is meant to be? I don't really fancy the ...Nge7 stuff ...

	The advantages and disadvantages of these two separate move orders are covered in "Transpo Tricks in Chess" by GM Andy Soltis. Whichever one to prefer is a matter of taste, in my opinion.

	What does author X say about this move? Why doesn't author Y mention that move?

	Well for really new ideas Watson covered this in the recent French dangerous weapons book. However that mostly looks at 4 Ngf3 Nf6 with either an early b5 or an early g5 (move 8 I believe.). Fun but mildly risky of course! I've played the g5 line. It's surprisingly different in it's details when compared to the equivalent Be7 stuff. Not sure quite how trustworthy it is mind (some very dangerous f4 pawn sac ideas for white.). I don't think that the theory of the 5 ed ed 6 Be2 c4 stuff has changed much recently. iirc b5 & dc are both meant to be OK. 5 dc maybe has changed more - I seem to remember Psahkis (the most recent edition) preferring Ne7 -> g6 after 5 dc Bc5 etc. Certainly more recent games in that section.

	I'm wondering if anyone with sources rather more modern than those I have here (the older Psakhis and such things!) can tell me whether there've been any significant new ideas lately in the 3 ...a6 Tarrasch. (After 3 ...c5 4 Ngf3, 4 ...Nf6 and 4 ...Nc6 both leave me dying of boredom -- and in the latter line isn't White better after 11 Bg5 as in Emms-Hansen? -- but 4 ...a6 strikes me as a much livelier option!) Has White got any improvements over those games of Dreev's with 5 dc Bc5 6 Bd3 Nf6 (Smirin-Dreev, Gelfand-Dreev, Campora-Dreev) or is this still OK for Black? And what of the 5 ed ed 6 Be2 c4!? lines? Are 8 ...cb and the sharper 8 ...b5!? both still OK?
