Can anyone tell me:

(1) After 7 ...Nh5 8 Nh2, [i]is[/i] [u]8 ...a5[/u] inferior? [i]NCO[/i] (p. 524, n.38) gives [u]9 Be2[/u] Nf4 10 Bf3 as a small White edge, but is this so? ChessPublishing seems to give only 9 g3 Na6 10 Be2, as transposing to the 8 g3 a5(!) 9 Nh2 Na6 10 Be2 line, which is surely fine for Black.

(2) After 7 ...Nh5 8 Nh2 Qe8, what does theory say about [u]9 g3[/u]? Usual now seems to be 9 ...f5 10 Be2 (10 Bg2!?) and here 10 ...Nf6 has been seen twice with the continuation 11 g4 Ne4 12 Ne4 fe 13 Be3 (or 13 Nf1), with some sort of light-square grip (though not necessarily an advantage?). Instead of 10 ...Nf6, [u]10 ...Na6[/u] has been seen twice (via the move order 8 Nh2 Na6!? 9 g3 Qe8), Hoi-Bronstein continuing 11 ef Nf6 12 Ng4 and Krasenkov-Xie Jun 11 ef Nf6 12 fg. What's going on here, and what's Black's best tenth move?

Annoyingly my CBM#133 is faulty so I'm going to have to wait until I can get it replaced to see Krasenkow's analysis.  But this looks very interesting.  I had been looking at precisely that 13.Qf3 line myself but had missed the idea of Nf1-e3.

Whilst not a subscriber to Chessbase Magazine, after reading that the man himself: Krasenkow was doing a survey on the Makogonov system in three parts in  issues 132 - 134, I decided to fork out the money to check it out. Krasenkow calls it the Bagirov system. So now we have three names for the system!

I was most interested to see that Krasenkow has to say about the 7...Nh5 line in view of Marko's analysis on 8. Nh2. In Krasenkow's own words, 7...Nh5 is "a playable but strategically risky line".

The key is that Markos missed 14. Nxe4!(instead of 14. Qxf7?!) as played in a correspondence game:   Jensen,J - Fernandez Ballon, 2005. Curiously, engines don't see White's advantage until some six move later when this position is reached.

Me thinks me like White here too.  Grin The question remains, does Black have better moves from moves 14 to 20

Ender, have you found something against 7...Nh5? I'm finding 8.g3 more interesting then 8.Nh2

Forget Rb1 - analysed a bit deeper - no problems for black at all

What about playing a semi-wating move like 8.Rb1  with the idea to follow with Bd3
f5 Bd3 Nf4 Bxf4 ef ef Bf5 Rf5 00
If black plays Na6 b4 is coming; after a5 white can play a fast a3/b4 as the rook on a1 is no longer pinned
The knight c3 gets mobil as b2 is additionally guarded;
some of my opponents played c6, then Bg5 f6 Be3

I play this for some time now with good results; but only in blitz games. No tournament games so far.

May be another route to a slight but steady advantage ??!

Greetings

Only detailed analysis can decide if 15.Ng5 or 15.0-0-0 is to be preferred. The latter might be the more sensible according the principle to include a maximum of pieces in the attack. After eg 15.0-0-0 Nxe2+ 16.Qxe2 Bf5 17.Rg3 Bg6 18.Ng5 or 18.Rh1 White must have fine compensation. Another line of defense is 15...Qe7 16.Rg3 Bf5 17.Ng5 Bg6 18.Rdg1 Rae8 19.Nce4 and nothing is decided yet, though I'd rather have White.

Hi Nelson!
How about 8 g3 a5 9 Be2 Na6 10 Be3 f5 11 ef gf 12 Qd2 f4 13 gf Nf4 14 Rg1 Bh3 15 0-0-0  ?
Isn't this improvement over Your variation? I think white may be slightly better here. He is pawn down but with big pressure on g and f files.

8 g3 a5 9 Be2 Na6 10 Be3 f5 11 ef gf 12 Bg5!? is also interesting.

Regards.

Hi MaSu,

Not sure why you posted this.
We've moved on from this Markos analysis which is not so far in dispute.
Please read the previous posts and comments on subsequent analysis would be appreciated.

[quote author=Ender link=1231803683/0#0 date=1231803682]Hi folks!
I have new GM. Markos book, where he states that after 1. d4 Nf6 2. c4 g6 3. Nc3 d6 4. e4 Bg7 5. Nf3 O-O 6. h3 e5 7. d5 Nh5 !? 8. Nh2
Qe8 9. Be2 Nf4 10. Bf3 f5 11. g3 Nxh3 12. Bg2 Qf7
black have equal game. And i tend to agree.

12.--Qf7 is a forced draw.
13.Bxh3-fxe4
14.Sg4! (other moves are good for Black)-Bxg4
15.Qxg4-Qxf2+
16.Kd1-Qd4
17.Ke1-Qf2+
draw

21.Rg6 iso 21.Bxh6 looks pretty good to me. In general I would say that this line is very worth trying. What I see after 14.Rg1 is open lines and diagonals vs. Black's King. There are no immediate threats, but that won't last long. White very quickly can direct all his pieces towards the right upper corner. Maybe I should try this attacking system as White myself. Am I right that 12.Qd2 is a novelty?

Hi Ender,

Just got back from business trip and have managed to track down some old notebooks from 2007 with some analysis as follows (to be honest I think some of it was computer generated/checked but it still seems reasonably valid.

After your worries about "losing the exchange and pawn just to get equal game" which is an improvement on your prevuius comments but what about the following:-
15...Ng2+ 16 Rg2 Bg2 17 0-0-0 Qd7 18 Rg1 Bh3 19 Bd3 h6 20 Ne6 Rf7 21 Bh6 Be6 22 de Qe6 23 Qg5 Nc5 24 Bh7+ Kf8 25 Bg7+ Ke8 26 Qh5 or Bg6 and white is better but perhaps you play too high level to agree with this.

After 14...Kh8 which I admit is a safer try I still offer 15 Ng5 which I labelled += but I would also like to add that It's no less a playable position than many other white tries against the KID and is relatively unexplored.

My analysis stopped here as I obviously spent more time on the less materially balanced positions. I will however investigate and report back in due course.

In the meantime I would welcome any improvement on blacks play in the 15...Ng2+ line from yourself or anyone else who is interested.

Regards,

Hi Enders,

Why don't you investigate 8 g3 a5 9 Be2 Na6 10 Be3 f5 11 ef gf 12 Qd2 f4 13 gf Nf4 14 Rg1 Bh3 15 Ng5 !?

What's you view on this continuation?

Nelson Smiley



1.d4 Nf6 Book 2.c4 d6 3.Nf3 Book g6 4.Nc3 Bg7 5.e4 Book O-O 6.h3 e5 7.d5 Book Nh5 8.g3 a5 9.Be2 Na6 10.Be3 f5 11.exf5 gxf5 12.Qd2 f4 13.gxf4 Nxf4 14.Rg1 Kh8 !   looks ok for black since h-file is locked.

1.d4 Nf6 Book 2.c4 d6 3.Nf3 Book g6 4.Nc3 Bg7 5.e4 Book O-O 6.h3 e5 7.d5 Book Nh5 8.g3 a5 9.Be2 Na6 10.Be3 f5 11.exf5 gxf5 12.Qd2 f4 13.gxf4 Nxf4 14.Rg1 Bxh3 15.Ng5 Ng2+ 16.Rxg2 Bxg2 17.O-O-O Qd7 18.Rg1 Bh3 19.Nxh3 Qxh3 20.Bh6 Rf7 21.Qg5 Qd7 22.Bh5 Kh8 !  is also ok for black.


And I don't want to sacrifice exchange and a pawn just to get equal game. I play on too high level to do it (1900-2300 sometimes 2400). Most of my oponent play this Nh5. This is logical move since white wasted time on 'stupid' moves like d5 and h3. So logical try is to open position, black has advantage in developement. I really don't want to test such sacrifices in games agains 2300 player. Plus black can play something else earlier and don't go for wild complications.
I can play something like d4 Nf3 Bb5 Nbd2 e4 and I'm also equal.

Hi Ender,

That's why I asked you to give me the next few moves indicating the lack of compensation rather than looking at the position in front of you statically and material biased.

If you were to give me the next few moves (from blacks point of view to indicate no compensation and I could find nothing wrong with your moves/assessment then I will bow down to your superior chess judgement but this has not been forthcomming.

If your not prepared to do some objective analysis then go and find another line that fits in with your subjective assessments.

I'ts just when You sacrifice exchange and a pawn you need to have threats, and what the threat here? For me white is material down for nothing.
