A Chance to Prepare Like a Grandmaster

In the next round of the Twin Cities Chess League, I am scheduled to play George Binger on Nov 18 2011. He is an Expert with a bit of history. He played Aleksander Wojtkiewicz in 1999 in Reno. That game is a treatment of the finachetto variation of the KID, that I have only seen once before when  IM Sean Nagel destroyed me in the June 2011 Rochester Summer Open: The Kavalek Defense (ECO E62). George Binger has another Kavalek defense game out on the web. Though both of Binger's E62 published games were losses for him, it is still a good opening for an above 2000 player against a class player, so I hope he is still playing it. I am going to take this opportunity to prepare against it anyway. After all, I may play IM Nagel again. I found Binger's games on the internet on 11/6 and started my preparation and this blog post subsequently. I will outline my preparation then finish and post after the game with the results. This is likely to be a mega post, or maybe I will cut it up into several, when I am done.

I do not recommend spending this kind of time to prepare an opening in normal circumstances. This is a special case. I know who my opponent will be, and I have published games (though a decade old) to work from. I do not think this is a good idea even in this case, really, because the games are too old, but I want to do it. It is a chance to play pretend.

There is a chapter on the Kavalek Defense in Wojo's Weapons vol 2. This book covers the fianchetto variation of the KID from a white perspective. I had not started this book, because I have done a lot of work on the KID before, and I have larger holes in my repertoire to fill in the symmetrical English. So, this chapter will form the backbone on which I will construct my preparation.

The Fianchetto Variation:

I began though with the chapter on the fianchetto variation from Starting Out: The King's Indian by Gallagher. Most likely, if Binger has abandoned the Kavalek defense, he is still playing the King's Indian, and I will choose the fianchetto variation. Gallagher's other KID book Play the King's Indian focuses on the black side of the Gallagher attack (6...Nbd7 7.Nc3 e5 8.e4 exd4) and the perhaps more precise (6...Nbd7 7.Nc3 e5 8.e4 8...a6), which can easily slip into the Gallagher attack, but is not as committal as 8...exd4. ST:TKI also focuses on these, but has two games plus a bit on the Panno variation (6...Nc6 7.Nc3 a6). All of these focus on attacking the c4-pawn, which is weaker than if the white light square bishop was on e2, and the danger to white along the a1-h8 diagonal if he plays b2-b3 to support the c4-pawn, or the weakness of f3 if the bishop returns to f1. White can easily misstep and lose a pawn, the exchange, or a whole piece, but if white can weather the storm, he should have at least a slight advantage going into an endgame.

The Kavalek Defense:

In my game against Sean Nagel, I played the silly 8.Bd2 not realizing that black's ideas here focus on attacking the d4 pawn and the rest of the a1-h8 diagonal by exchanging or pinning the Nf3. The main line goes 8.e4 Bg4 9.h3 Bxf3 10.Bxf3 which George Binger faced in his game against Wojo. 10.Qxf3 is an alternate main line that George Binger faced in 1997 in another game.

Here in Wojo-Binger, Binger played the best move for black, 10...Nfd7 opening up pressure on the d4 pawn and the a1-h8 diagonal. Wojo replied with the tricky 11.Rb1 c5 12.d5 and Binger took the apparent pawn sacrifice with 12...Bxc3 13.bxc3 Qxa2 14.Bh6 Re8 not realizing that 15.Rxb7 Nb6 does not really trap the rook.
Wojo-Binger after move 15...Nb6
16.Qa1!? Qxc4? 17.Rxb6 because the a7-pawn is pinned 17...axb6 18.Qxa8 Qxc3 and white is up a piece for two pawns, has the two bishops and will be able to pick up the b-pawn. After a few more moves Binger decided that that was enough against a grandmaster. 16...Qxa1 would have preserved the position and likely gone into a drawish endgame (at least I could not find a winning line for white). Wojo was extremely good at such positions, so he would have had good chances to win the game. I on the other hand, have a hard time finding a winning idea for that endgame.

  1. Where would Binger improve on this game?
  2. How should white reply to each of these improvements?
  3. Does white have a better move earlier?
  4. Is 9.h3 a waste of time as black wants to remove the Nf3 anyway?
Improvements for black and responses/avoidances:

16...Qxa1 leads to a drawish endgame. 17.Rxa1 Nbd7 18.Raxa7 Rxa7 19.Rxa7 Ra8 20.Rb7 Rb8 and either white repeats with Ra7, or goes into an endgame, which is totally wrong for the two bishops. Two bishops against knights want an open center and mobile pawns on both flanks. Because both knights can focus on one square, they can overpower either bishop. Eventually the position will open up and the bishops come into their own, but I think white will be fighting for a draw, then. 16.Bg4 is better than 16.Qa1

15...Nf6 16.Qa1 gives a better version of the game, because if black plays the best 16...Qxa1, white retains at least one rook in the endgame.

15...Ne5 is much better than trying to trap the rook with 15...Nb6 (probably because it hinders 16.Bg4). White should reply 16. Be2 and things get complicated from there.
after 15...Ne5 26.Be2
The main ideas revolve around mating threats and the restricted nature of black's pieces.

The black King is lonely, the Rb7 threatens the 7th rank and can sacrifice itself on e7 to open up the f6 square (16...Nxc4? 17.Bxc4 Qxc4 18.Qf3 {threatens  19.Rxe7 Rxe7 20.Qf6 and the mate threat forces Qxc3 and loss of black's Queen}).

Black has trouble developing the Nb8 without losing it (16...Na6 17.f4 Nxc4 Qd3) 17(16...Nbd7 17.f4 {wins a piece, but black gets counterplay, may be black's best choice, but hard to see})

Trying to trap the rook with (16...Qa6 17.Qb1 Nbd7 18.f4 Nb6 19.Rxb6 axb6 20.fxe5 dxe5{results in nominally equal material, but white has a dangerous Kingside initiative} 21.Bg4 Red8 22.Qd3 Qa4 23.Qf3)

13...Qxc3 taking the other pawn leads to trouble, also. 14.Bg5 f6 15.Bh6 Re8 16.Rxb7 
and black's Queen is offside while white attacks on the kingside with the help of the rook on the 7th rank. White threatens Bg4 and if black plays 16...Ne5 then 17.Be2, and the Rb7-b3 can drive the black queen away if needed. 

12...Qb4 helps white, because 13.a3 chases the queen away.

12...a6 and 12...Na6 are less committal moves that work better for black. This may be the trickiest area for white to maintain an edge. If black opens the center (...e6), then the bishops should begin to exert their influence, while if the center remains closed, white should be able to advance pawns on the kingside.

11...a6 allows 12.b4 which leads to 12...Qd8 13.Be3 b5 14.Be2 bxc4 15.Bxc4 (Hansen-Mortensen Taastrup 1998)

11...Na6 hinders b2-b4, but12.a3 c5 13.d5 is much like 12...Na6, but white has possibly wasted a move with 12.a3.

10...e5 and 10...Nbd7 kind of lead to the same place. After 11.Be3, the best move for black is the other. White should sustain an edge after 12.d5 cxd5 13.cxd5 where the action will take place on the queenside and the likely fight over the c-file will result in a liquidation of the rooks. White's bishops controlling the f1-a6 and g1-h7 diagonals should make this hard for white to lose.

Better moves for white:
Instead of 16.Qa1, Houdini likes 16.Bg4 Qa6 17.Rc7+-. The rook is safe, pressures the 7th rank, and black has a tangled queenside. White has a deep attacking threat in 17.Be6 fxe6 18.Qg4

10.Qxf3 is an alternative, with which Johnson,L beat Binger in 1997. It has a lot to recommend it: the Bg2 remains safe, the h3-pawn is defended, and the queen is off the back rank, so Rfd1 is easily played to defend d4.

9.h3 is not a waste of time.
h3 is a useful move for white in many KID variations. Here, it will prevent the Nf6 from opening up the long diagonal with ...Ng4, which would make a white Be3 uncomfortable, or with a mate threat if ...Qh5 has happened. With h3 in place, black must interfere with his own development (...Nfd7, ...Ne8) to open up the long diagonal. It also does not allow black to delay the exchange on f3 for a more opportune time.

What about George Binger's other games?
In the late 1990s for which I have published games, Binger played the Sicilian Dragondorf and the KID. He likes a kingside fianchetto and queenside pressure. He played a King's Indian Attack as white versus a French Defense. I would guess he favored tactical games.

My Game with George Binger
was not a Kavalek Defense. He played the KID, and I played the fianchetto variation, but he chose the Panno.  My preparation fantasy was fun, but in the end not productive. I did play over a couple of games of the Panno variation, but I have not really prepared for it. I think he was definitely better coming out of the opening. After 43 hard fighting moves, we agreed to a draw. I may decide to make a post about the game, after I study it during the coming week.

So I still have to get past move 10 in any memorized opening preparation during a tournament game.
