Caro Kann - Gurgenidze System [B15]

1. e4 c6 2. d4 g6 3. Nc3 d5

3...Bg7 can lead to Robatsch positions. I'm headed for a Caro Kann Gurgenidze. The CK Gurgenidze is part of the "Zoom" opening repertoire which aims to present the player with the same typical positions as Black or White. The other base openings recommended are the Gruenfeld against Queen Pawn openings and the Catalan as White.

4. f3

Nf3, e5, and h3 are all more popular alternatives to 4.f3. The text move has seen success, but recently it has fallen out of favor. Here it inhibits, at least for a time, development of the King Knight and King Bishop. In this game White's King Bishop will play almost no role. I will look to restrict the Bishop by use of b4 at the right moment.

4... Bg7 5. Be3 dxe4 6. fxe4

White has the typical strong pawn center. As a "recent" devotee of the Hypermodern approach, I'll seek to attack the center with pieces and attack White on the Queenside flank. There was a time when I was loathe to move any of the three pawns in front of my King or to concede the center at any point. Now, I find many of those games quite boring even when I am successful, at least in correspondence play. I find that I think nothing of letting an opponent push a center pawn down the board witrh little restraint in many cases, as long as I have chances of a strong wing attack and my King is safe!

6... Nf6 7. Nf3 O-O 8. Qd2 Ng4

8...Qa5 was also playable to avoid a cramped game and attack on the Queenside where White will castle.

Kalinitschew - Cicak Deizisau 2007 1. d4 g6 2. e4 Bg7 3. Nc3 c6 4. Be3 d5 5. f3 dxe4 6. fxe4 Nf6 7. Nf3 O-O 8. Qd2 Qa5 9. Bh6 Rd8 10. Bxg7 Kxg7 11. O-O-O Bg4 12. Qf2 Bxf3 13. Qxf3 e5 14. Bb5 Qc7 15.

9. Bg5 Qc7 10. O-O-O

White has a prototype center and centralized pieces. White should be +=, right? Time to challenge the center.

10... e5 11. d5 Nd7 12. h3 Ngf6 13. d6 Qd8

Black is retreating in the center and Kingside. White is expanding and has a central passed pawn! Whatever will Black do? I refer the reader to Nimzovitch who stated that a passed pawn must be blockaded and eventually executed as a criminal.

For all practical purposes, White's central pawns are isolated and the d pawn is over extended. White will be required to marshal all of his forces to hang on to it while all I must do is blockade it until the time is ripe for decapitation. Of course, that is a big all and White can ruin Black's world on the slightest misstep by the second player.

White's best moves here are limited to Kb1, Qe3, a3, and Bc4.

14. Kb1 b5

Since he didn't develop the King Bishop I'll go ahead and make life difficult for it while expanding toward his King.

15. Qe3 Qb6

In a cramped position one exchanges off forces to free the position. White will either acquiesce to the exchange or retreat his Queen. Either is a plus for Black.

16. a3

16. Qe1 might have been preferable when the Queen could re-emerge on the Kingside at g3 or h4.

16... Qxe3 17. Bxe3 a5 18. b4

18. Bd3 was another option.

18... axb4 19. axb4

All of a sudden White's King seems vulnerable.

19... Rd8 20. Be2 Ne8

The start of reorganizing my Knights and Queen Bishop to let the Bishop take over blockade duty. The Knights are destined for invasion duty in the center from e6 and f6. The King Knight was also in the way of the f pawn who is headed for f5.

Here I intended an eventual doubling of the rooks on the a file, knights at e6 and f6, light Bishop blockading the d pawn, and the dark Bishop attacking from f8.

21. Rd2 f5 22. Rhd1 Nef6 23. Ng5

23. exf4 seemed better to me.

23... Nf8 24. h4 h6 25. Nh3 Bd7

I thought about 25...Ra6 but stuck to the plan. The Bishop is right at home at d7.

26. Kb2

The alternative 26. Bb6 had no teeth.

26... Ra6 27. Nf2 Ne6 28. Rb1 Rda8

Reorganization complete with malicious intent on the a file which has White's Queen Knight frozen to c3. The d pawn is isolated and demands protection even though no Black piece is attacking it. White's King Knight is out of the game and he has no time to bring it back. White's King is exposed and none of his pieces have scope beyond the third rank despite his former strong center.

29. Rdd1

White has nothing better.

29... Nd4!!

Advantage Black! From here it is a matter of simplifying and getting the point.
