	hello, for 6. Be3 you can see this old thread: http://www.chesspub.com/cgi-bin/yabb2/YaBB.pl?num=1104416123/30#30 i watched aeroflot live online yesterday, and saw this amazing game : [Event "Aeroflot Open 2007"] [Site "Moscow"] [Date "2007.??.??"] [Round "8.15"] [White "Kurnosov, Igor"] [Black "Volkov, Sergey"] [Result "0-1"] 1. e4 e6 2. d4 d5 3. Nc3 Nf6 4. Bg5 Bb4 5. e5 h6 6. Bd2 Bxc3 7. bxc3 Ne4 8. Qg4 Kf8 9. Bd3 Nxd2 10. Kxd2 c5 11. Nf3 c4 12. Be2 b5 13. a4 bxa4 14. Rxa4 a5 15. Qf4 Nc6 16. g4 Ke8 17. h4 Ra7 18. h5 Qe7 19. Rg1 Rf8 20. g5 hxg5 21. Nxg5 f6 22. Nh7 Rf7 23. Qe3 fxe5 24. dxe5 Qh4 25. Rg4 Qh2 26. f4 d4 27. cxd4 Ba6 28. Kc3 Bb5 29. Nf6+ gxf6 30. Rg8+ Rf8 31. exf6 Rxg8 32. Qxe6+ Kf8 33. d5 Nd8 34. Qd6+ Kf7 35.

	About Janowski variation (6.Be3) I recorded recent games in the line 6.Be3 Ne4 7.Qg4 g5!? (Shirov-Volkov,Rethymon2003) After 7..g6 8.a3 Bxc3+ 9.bxc3 Nxc3 10.Bd3 leads to games: Klovan-Makarichev,URSS 1978 (ECO); Shirov-Brynell,Rethymon 2003; Romanishin-Bronstein,URSS 1978 (ECO) but two recent game with 10..b6 and 10...Nc6 11.h4 Ne7!? 12.h5 g5 13.Ne2 are Naidijsch-Stellwagen,Corus 2006 and Najer-Nepomniaschcky,Moscou 2006 One point to note is why Black doesn't play 7..g6 8.a3 Bxc3+ 9.bxc3 Nxc3 10.Bd3 and now 10...c5 ? Maybe the answer is in the game: 11.dxc5 Qa5 12.Qb4 (12.Bd2 Qxc5 Dom and not 12...Qa4? 13.Qb4! (Suetin)) Qxb4 13.axb4 Nc6 14.Rh3 Iordachescu-Foisor, Medoc wine open 2002 Need some analysis: 7..g6 8.a3 Bxc3+ 9.bxc3 Nc6!? (Dom) One idea is 10.c4 Nxd4! 11.Bxd4 c5 12.Bxc5 (12.Be3 Qa5+ 13.Ke2 Qc3) Nxc5 13.cxd5 Qxd5 14.Nf3 Bd7 = (silicon monster) or 10.Nf3 Ne7! 11.Bd3 Nxc3 12.Bd2 (12.oo Qd7 13.Bd2 Qc6) Na4 13.oo Nb2!? long ride for the horse from g8 to b2 After 7...g5!? A) 8.a3 h5! (given only in Psakhis's book) Govedarica-Ruckshloss,Trnava 1990 (Psakhis) or Belov-Alavkin,Sochi 2004 or Veselovsky-Glek,Moscou 1984 (MCO) ...maybe 9...h5! is a good surprise weapon B) 8.h4 h5 9.Qd1 (the queen sacrifice hxg5 leads only to a draw in Shirov-Volkov,Rethymon 2003) Lanin-Skorchenko,Russie 2006 (Lanin)

	Many thanks for these responses. I'll make another post myself as soon as I feel I'm in a position to say something useful!

	I saw that game live with great interest. Shirov-Volkov in the same event was also very interesting. The Mac had a period when it was thought respectable (which depressed me: I always liked its slightly louche air), of which 2003 was about the high-water mark. I think it might have gone a bit backwards theoretically since then. Still more respectable than in my day, I dare say.

	Hmm, after seeing the following game a few years back I assumed that the MacC was regarded solid as rock nowadays. Albeit based on the sole assumption that Stellan wouldn't have played it otherwise... Shirov,A (2730) - Brynell,S (2510) [C12] ECC, Rethymnon GRE (1), 2003 1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Bb4 5.e5 h6 6.Be3 Ne4 7.Qg4 g6 8.a3 Bxc3+ 9.bxc3 Nxc3 10.Bd3 Nc6 11.h4 Qe7 12.Nh3 Bd7 13.h5 gxh5 14.Qf3 Qh4 15.Qf4 Qxf4 16.Nxf4 0-0-0 17.Rxh5 Ne7 18.f3 a6 19.Kd2 Na4 20.Rah1 Bb5 21.Rxh6 Rxh6 22.Rxh6 Bxd3 23.cxd3 c5 24.dxc5 d4 25.Bf2 Nc6 26.Bh4 Rf8 27.Ne2 Nxc5 28.f4 Rg8 29.g3 Kd7 30.Rh7 Ke8 31.Ng1 b5 32.Nf3 a5 33.Ng5 Rf8 34.Rh6 Kd7 35.Nh7 Rb8 36.Nf6+ Kc7 37.Rh7 Rf8 38.Bg5 b4 39.Bh6 Ra8 40.Rxf7+ Kb6 41.axb4 axb4 42.Nd7+ Nxd7 43.Rxd7 Ra2+ 44.Kc1 Rg2 45.f5 Nxe5 46.Rxd4 Nc6 47.Rc4 exf5 48.Be3+ Kc7 49.Bf4+ Kd7 50.Rc5 b3 51.Rb5 b2+ 52.Rxb2 ½-½

	Personally I think 6 Be3 is a very critical line (I used to play the Mac with great enthusiasm and fair success a long time ago, and still would do if it weren't for 4 e5, 3 Nd2 3 e5, etc.). I found the game Cuijpers-someone very hard to improve upon. Sorry: imprecise and unhelpful I know. Moro's ...Nd7 idea is known but perhaps not in this position. Usually the idea is ...b6 ..Ba6 and perhaps ..Qa3 while guarding f6. I suppose that Leko's queen capture on d4 was a reaction to these ideas, since once f6 is defended the queen is less use on f4.

	"brief" I will try, but I don't know where are clouds... I will only give some variations I recorded with starting moves of the recent Leko-Morozevich,Linares 2007 game (www.chessbase.com), with few comments: 1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.Bg5 Bb4 (McCutcheon) 5.e5 h6 6.Bd2 (6.Bh4!? Bernstein attack ; 6.Bc1 Dr Olland = Dutch variation ; 6.Be3 Janowski variation) Bxc3 7.bxc3 Ne4 8.Qg4 g6 (8..Kf8) Lasker variation and now: 9.Bd3 (8.h4!? is maybe used to transpose in Marockzy attack with h4, but Black can try 8...Bd7 to play Murey idea Bd7 which occurs in other lines) Nxd2 (9...Bd7!? Murey idea ; Murey showed me the idea in Condom july 2004 after one of my McCutcheon game..but there are two lines annoying me: 10.Bc1 and 10.Ne2) 10.Kxd2 c5 11.h4!? (Marockzy attack ; one of the sharpest lines in McCutcheon) Qa5 (novelty in the game Seirawan-Makaritchev,Reykjavik 1990 ; I feel the old line with 11..Nc6 is better but it's difficult to prove this feeling) 12.Nf3 (12.Rh3 Nc6 13.Bxg6 Nxd4!) and now Morozevich played 12...Nd7 (novelty?) but I don't know why he didn't play 12..Nc6 13.Qf4 (13.Rhe1 cxd4! Hebden-Vaiser,Bern 1992 (NIC YB 46) ; 13.dxc5 Bd7 followed with ooo (Suetin)) b6!? (13...cxd4 14.h5 when White is better is better in all lines, with the sacrifice 14...g5 15.Nxg5!! hxg5 16.Qf6 Marockzy 1921 ; 13...Bd7 14.Qf6 and small advantage to White) 14.h5 gxh5!? (14..g5 15.Nxg5 or 15.Qf6) 15.Rxh5 Ba6 Kovalek-Glek,Allemagne 1994 (NIC YB 46)

	Can anyone give me just a brief indication of current MacCutcheon theory, especially in the 6 Bd2 line? Is 4 ...Bb4 currently under something of a cloud, or not? Thanks in advance!
