14.Bd2!
This is a very important prophylactic move.
Gulko: If I had played 14.Be3?! it would have allowed him to exchange off the dark-squared bishop and develop his knight to e7; e.g. 14...Bb4! 15.Rac1 Nge7 with equality.
14...Nh6 15.Bxh6!
The most important element is disturbing the coordination of his rooks. Now I have the direct plan of taking over the c-file. I have the more pleasant position with a clear-cut plan, whereas he must come up with something quite sophisticated.
15...Rxh6 16.Rac1 Kf8 17.Na4
Gulko: Now my knight is heading to c5 or my queen to b5 with a lot of pressure on the queenside.

The main idea for Black is to play ...c6-c5, which would solve all his problems. However, White can use the main drawback of Black's position (the poor placement of the knight on a5) to prevent this plan. It is this aspect of the position that is unique and, therefore, White should not apply rules in a general way but in a specific way, adapting to the positional demands on the board.
15.Qd2!
The natural 15.Ne4? allows 15...c5, giving Black a good game.
15...b4
Unsatisfied with the development of the game, Black tries for complications.
The quiet 15...Qd8!? would permit White to prevent ...c6-c5 by 16.Qe3! , after which the invasion of the c3-knight via e4 on Black's weak dark squares would give White a tremendous position. (Again not 16.Ne4 because Black has c5.
16.Ne4 Ba6 17.Nc5! c3 18.bxc3 Nc4 19.Qe1 Nxc5 20.dxc5 Qxc5 21.cxb4 Qb6 22.Qc3!+/-

πΈ Zagreb Interzonal 1987
βͺοΈViktor Korchnoi, the veteran grandmaster and many times world challenger, now living in and playing for Switzerland, was the victor in the third and last of the interzonals, Aug. 1-23, at Zagreb, Yugoslavia. Playing aggressive, superlative chess, Korchnoi fashioned a score of 11-6, a full point more than any other player could muster. The United States finally qualified a player from these interzonals into the next round of the world championship competition when Yasser Seirawan parlayed an elegant technique and a delicate touch to tie for second place with International Master Jaan Ehlvest of the Soviet Union. These three players will now join 11 others going into the candidates' matches scheduled for late January and early February in St. John, New Brunswick.
βͺοΈThe strength of the Zagreb interzonal tournament is obvious from the roster of grandmasters trailing: Predrag Nikolic of Yugoslavia, Jes'us Nogueiras of Cuba, and Julio Granda Zuniga of Peru, with 9 points; Eugenio Torre of the Philippines with 9; Jozsef Pinter of Hungary, Lev Polugayevsky and Vereslav Eingorn of the Soviet Union, and Yehuda Gruenfeld of Israel, with 8.
β¦οΈKorchnoi's imaginative effort against Seirawan won the best-played-game prize!!
