I tried to analyse the position after 19. ...a5, but this is really a jungle with no clear compass - no surprise - but what I noticed, that Rc1 should go to c6 and provoke a sacrifice, in best case against Bc8.

By the way, this line is seen in a game Ragger-Grischuk from the latest KID update.

Yes, thanks for the reminder.  Thinking about it, it may have been Amet's initial post in that thread that got me to first look at this line.  But, since I decided not to play it with either color, I didn't keep up with the subsequent discussion.  I guess you could say "I lost my interest."

Vigorito does indeed do a great job here, but I was referring very specifically to this thread, which covers this line and the evolution of it's ideas in fairly excruciating detail:

KID Bonanza

Not sure about how much of the analysis meshes with this specific sub-variation, but there's only one way to find out!

Most importantly, have you checked "the thread" here on ChessPub?  Cheesy


I finally got a chance to check the Chess Publishing archive.  Was happy to see that David Vigorito analyzes all the key games in this line.  Great stuff!!

@gewgaw -- I last looked at this line a few years ago, so my knowledge may be out of date, but AFAIK, 18.Be1 is considered the strongest move for the reason that you state.  White obviously wants to play Nd3-b4-c6 if possible.  Black's 18..a6 is theory and now you want to play 19.Nc3 rather than 19.Na3.  The idea of 19.Nc3 is to protect the e4 pawn so as to hold up Black's ..g4 advance (which after Nc3 could be met simply by fxg4).  After 19.Nc3, 19..a5 is theory, preventing the Nd3 from getting to c6.  Your 20.Qb3 and 21.Nc4 are a bit unusual, I think.  In most of the games I looked at in this line, White puts the Knight on b5 and his heavy pieces on the c-file.  Generally, the set up is Rc4/Qc2/Bf2/Rc1.  See, for example, Gyimesi-Polzin, Bundesliga 2010.

Thanks a lot @LeeRoth, very helpful. I a few days, I'll post some lines to this variation - at least I'll send them to you  Wink

Oops, what I said indeed pertains to 19. Nc3, not 19. Na3.  Regarding the continuation of Gyimesi-Polzin, the article only mentioned 20...g4 21. Rc6 Bf8.

Speaking of NIC and 19...a5N, I recalled a Yearbook article by IM Erik Hoeksema in which that was considered a good novelty, but that was back in 2010.

(Even more historical:  18. Be1 was mentioned as deserving attention by R. Byrne and Mednis in ECO in 1978.)

Hi all,

I was in the mood to play the classical KID with white and this is what happended:
1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 0-0 5.Nf3 d6 6.Be2 e5 7.0-0 Nc6 8.d5 Ne7 9.Ne1 Nd7 10.Nd3 f5 11.Bd2 Nf6 12.f3 f4 13.c5 g5 14.Rc1 Ng6 15.Nb5 Rf7 16.Ba5 b6 17.cd6 cd6 18.Be1 a6 19.Na3 a5N 20.Qb3 Bf8 21.Nc4 Rb7 22.a4 h5 23.Bf2 Nd7 24.Qc3 Nc5 25.Ra1 Bd7 26.b3 g4 27.Rfb1 Qg5 28.Be1 h4 29.Nc5 bc5 30.fg4 Bg4 31.Bg4 Qg4 32.Qf3 Qg5 33.Kh1 Rba7 34.Qh3 Qf6 35.Ba5 Ra5 36.Na5 Ra5 37.b4 cb4 38.Rb4 Ra7 39.a5 f3 40.Qf3 Qf3 41.gf3 1-0

Of course, I've checked my game with an engine, but he can't help me around move 18 and so forth, so I write my thoughts and hope for some help by the forum.

18.Be1 - "some years ago, I read an article by Giri in NIC, that square b4 belongs to the knight, so I played it"

18. ...a6 - "oh dear, he really knows his stuff and I've no real idea, what to play"

19. Na3 - what to play, 19.Nc3, 20.a4, 21.Nb5, rooks on c-file, this takes ages, Black will wrap me on the kingside, so let's try 19.Na3, maybe I can put some pressure on the b6 pawn.

19. a5N - my opponent wants to controll xb4 to limit my Nd3, so far 19. ...b5 and Bb7 was played

20. Qb3 - I was impressed by Black's set-up; not really sure what to play, so I sticked with my plan to play against b6

20. Bf8 - overprotects d6, Rg7 is possible to play g5g4

21. Nc4 - I've nothing, except of this lousy attack against b6

21.Rb7 - Black protects everything, rolls with his pawns on the kingside and in the right moment, he swaps back with his rook to g7; actually, he can even play on the queenside with b6b5 in the right moment - I'm lost.

22. a4 - yes, this pawn can even be a weakness (Bd7,Qe8), but I've to stop b5 somehow

22. h5 - I'd have played g4, without h4, maybe xh5 can be used by a piece, but okay, I still have nothing

23. Bf2 - arg, what a move, I invite him to play g5g4g3, but I see nothing better

23. Nd7 - yes, heading for c5, I've nothing, my pieces are somewhat misplaced

24.Qc3 - maybe b4 can work for some day

24. Nc5 - as expected, Black controlls the board, someday he'll finish me of on the kingside

25.Ra1 -so painful
25.Bd7
26. b3 - sooo painful
26.g4
27.Rfb1 - preparing b4, protecting b3, maybe ra2, King gets some luft to escape
Qg5 - okay, g4g3 and this horrible game is over, what to do
28. Be1 - hm, strange, without g4g3 he has nothing, what can he play?
28.h4 - wait a minute, this doesn't really work, can I really survive this horrible position?
29.Nc5 - the so forth

I wasn't in the mood to celebrate after the game, I had the feeling, I understand nothing about the KID and my whole setup, which looks so straightforward (c5, Rc1, Nb5, Ba5) leads to nothing.

Who can help me to understand this line better?
