|Apr-18-06|| ||sneaky pete: 13... fxg5? is a well known mistake.
Theory (analyses by Sakharov and Keres) recommends 13... Bg4 14.Bf4 Kf7 15.Qxc4+ Nd5 16.Nd2 .. (16.Bxc7? Rc8! 17.Bxd8 Rxc4) 16... Be6 17.Bg3 Re8 18.Ne4 .. when white is only slightly better.
Black may try 12... Be6 when 13.Bxe7 Qxe7 14.d5 0-0-0 15.Qa4 Rxd5 16.Qxa7 .. is unclear but probably still favours white and 13.Qe2 Qd5 14.Bxe7 Kxe7 is equal, according to Bogolyubov. Not good is 13.d5? Qxd5 (14.Qd4 Qxd4 15.Nxd4 h6 16.Nxe6 fxe6 17.Rxe6 hxg5 18.Rae1 0-0-0! 19.Rxe7 c3 20.Rc1 c2 21.Ree1 Rd2 22.h3 Rf8 23.f3 Kd7 0-1 Vos vs Elich, correspondence 1985).
|Apr-19-06|| ||tpstar: <sneaky pete> Thank you very much for the analysis. I haven't played the Main Line GP for years, so I have two questions please:|
1) Does Black do better with 8 ... Nxc3 or 8 ... Bxc3 instead?
2) Any recent theoretical updates?
Thanks a lot. =)
|Apr-22-06|| ||Catfriend: <tpstar> I think Opening Explorer can answer your question:) |
8..Nxc3 9.bxc3 Bxc3 is plain bad, allowing 10.Qb3!
9..d5 isn't as losing, but I'd still play 8..Bxc3 as black. Then, 9.bxc3 is met by 9..d5, and I'll let yoo judge;)
So, the main line should be 8..Bxc3 9.d5 with mutual chances.
|Apr-22-06|| ||Averageguy: <tpstar> The line which Greco gave after 9...Bxc3 is 10.Qb3 Bxa1 11.Bg5 Ne7 12.Ne5 Bxd4 13.Bg6 d5 14.Qf3+ Bf5 15.Bxf5 Bxe5 16.Be6+ Bf6 17.Bxf6 gxf6 18.Qxf6+ Ke8 19.Qf7# This is still commonly seen I beleive in junior/scholastic chess when the black player gets to greedy.|
|Apr-22-06|| ||tpstar: <Catfriend> <Averageguy> Thank you for your responses. I was asking about the position after 8. 0-0:|

I used to play 8 ... Nxc3 9. bxc3 d5! (of course Black never captures twice on c3 ;>D) but some disagree that 9 ... d5 truly equalizes for Black. So I wonder if 8 ... Nxc3 or 8 ... Bxc3 gives better chances. Thank you. =)
|Apr-22-06|| ||WannaBe: <tpstar> I'm surprised that you haven't put it through infinite analysis on your computer yet. :-)|
8...Bxc3 9. bxc3 d5 10. Bd3 f5 11. c4 Be6 12. Bxe4 (+1.04)
8...Nxc3 9. bxc3 Bxc3 10. Rab1 d5 11. Bb5 12. Ba3 Qf6 (+1.35)
|Jan-03-07|| ||Infohunter: Enjoyed your analysis, <sneaky pete>. Ever thought about uploading that Vos vs Elich correspondence game to the <cg> database?|
|Aug-02-08|| ||arkansaw: can anyone check the lines after 14...Rf8?

I am really curious to find out what happens after depth 23, as my computer is only good enough up to depth 22 or so:
Rybka 2.3.2a 32-bit : 15. Re5 g4 16. Ng5 h6 17. Nh7 Rf7 18. Rae1 c6 19. Qc5 Qd7 20. a4 b6 21. Qc4 Qd6 [%eval -83,22]
|Aug-10-10|| ||tpstar: "A former suggestion for Black to equalize was 8. 0-0 Nxc3 9. bxc3 d5 attacking the bishop on c4, but here White gets very good play with 10. cxb4 dxc4 11. Re1+ Ne7 (11 … Be6?? 12. d5) 12. Bg5 Leonhardt vs J Perlis, 1908 . Thus the current consensus is that 8 … Bxc3 gives Black better chances than 8 … Nxc3."|

Yes, the kibitzing on this site is very instructive indeed. =)
