Game 10:  Eliskases vs. Gligoric

0.
@Q0
[Introduction: The main event of 1953 was the Neuhausen-Zurich Candidates Tournament, scheduled for the fall. To get in some practice before then, the Yugoslav champion Svetozar Gligoric decided to accept some playing invitations in South America: Mar del Plata, Rio de Janeiro, and Montevideo. Accompanying him was his second, Petar Trifunovic. The tour apparently went well. Gligoric won all three tournaments, losing only one game out of thirty-nine. He certainly got his practice.  

For our tenth tutorial, we pick up the action in Argentina, the Mar del Plata tournament of 1953. Gligoric, your partner, has the Black pieces against a former Austrian champion (hometown Innsbruck), who has been living in Argentina since the Buenos Aires Olympiad of 1939. That's Erich Eliskases, and he has the White pieces. The opening is state-of-the-art King's Indian Defense (for the year 1953), the Taimanov-Aronin Variation.  The opening is important. 

Only a few months before, in the 20th Soviet Championship (Nov-Dec 1952), Mark Taimanov had introduced a dangerous new system for White, using it to defeat both Aronin and Bronstein within the space of a few days. The King's Indian Defense was in crisis, and for players like Gligoric who relied heavily on the King's Indian, new and accurate methods of defense had to be worked out. 

This was the role of Mar del Plata and it produced three significant games: Najdorf-Gligoric, Najdorf-Trifunovic, and Eliskases-Gligoric. The last two games were played on the same day. It turns out that the main beneficiary of all this King's Indian activity was not Gligoric, but Najdorf, who twice figured on the White side. With his newly gained knowledge, Miguel Najdorf, the transplanted Pole, took up the Black pieces against Taimanov himself at Zurich, and won a stunning encounter. Taimanov-Aronin was knocked out of commission (for some thirty-five years). It was only in the late 1980's that folks ventured to take another look. And they're still not sure.]

[Conclusion: When White closes down the center, 8. d5, the play automatically moves to the flanks, White on the queenside, Black on the kingside. Gligoric has one luxury that Eliskases does not: he's playing for bigger game so he can afford to sacrifice. The White king is more important than any target White can find on the queenside. And sacrifice he does, 16...g4!, though it's only a pawn, 19. Qxb7. 

The follow-up is 19...f3!, punching holes in White's castled position. White could try to keep the kingside closed with 20. g3, but then he has to contend with a big Black pawn sitting on f3, and Gligoric can still attack after 20...Bh6 or 20...h5. 

Eliskases concludes that his best chance to break the attack is to offer up the exchange (moves 20 through 24). He gets two pawns in return. Immediately thereafter Gligoric produces 24...Bd4, and it quickly becomes apparent that Black merely has to line up his heavy pieces on the g-file to threaten mate at g1. 

Eliskases adjusts with swift counter-action in the center (moves 25-32), designed to distract Gligoric from his bellicose aim. And it looks like he succeeds. The dark-square bishop is traded off and White works a dangerous passed pawn all the way down to d7. Gligoric's brilliant 33rd move, a Rook sacrifice, destroys the illusion. The Rook is taken, 34. Nxd7, but after 34...Qg6, the attack on the g-file flares up once again. 

This time there is no satisfactory defense. Desperately, Eliskases offers his queen for rook and knight, and manages to stave off mate. But the ending is hopeless. Gligoric's queen and passed d-pawn quickly overcome the two White officers. 

A terrific fighting game and a model in how to conduct the Black side of the King's Indian. Just don't ask how Gligoric did at Zurich, for 1953 was Smyslov's year, not Gligoric's.]
