18th Chess Olympiad , Lugano 1968.

@UnityChess

The 18th Chess Olympiad, organized by FIDE and comprising an open[1] team tournament, as well as several other events designed to promote the game of chess, took place between October 17 and November 7, 1968, in Lugano, Switzerland.

The Soviet team with six GMs, led by world champion Petrosian, lived up to expectations and won their ninth consecutive gold medals, with Yugoslavia and Bulgaria taking the silver and bronze, respectively.

@UnityChess

Judit Polgar, pictured here, was the highest scoring member of her team. Following the defection of Elena Akhmilovskaya Donaldson after the tenth round, the Hungarian team triumphed, winning the tournament by half a point. Akhmilovskaya would later become a three-time U.S. Women’s Chess Champion (1990, 1993, and 1994).

🔷 Chess History - Tournaments
🔹 Tilburg 1989
🔹 September 15, 1989 to October 02, 1989
🔹 CHAMPION: Garry Kasparov | 12/14 (+10 -0 =4)

🔰 The 13th annual Interpolis international chess tournament was a category XV ( In Wikipedia : Tilburg 1989 - cat.16 (2626) ) event held in Tilburg, The Netherlands from September 15th to October 2nd, 1989. Eight grandmasters, including the world champion, were invited to participate in the double round robin event, including (in order of ELO): 👇
🔅 Garry Kasparov (2775),
🔅 Vassily Ivanchuk (2660),
🔅 Viktor Korchnoi (2655),
🔅 Ljubomir Ljubojevic (2635),
🔅 Simen Agdestein (2605),
🔅 Gyula Sax (2580),
🔅 Johann Hjartarson (2555), and
🔅 Jeroen Piket (2540).

🔰 In one of the most impressive tournament performances of all time, Kasparov dominated the field of top grandmasters as if it were an exhibition. He scored 10 wins and 4 draws for a total of 12 points out of 14 possible, finishing 3.5 points over second place Korchnoi and 5 points over shared third! It was a triumph few world champions would ever display while crowned, and it was a feat surpassed only by Anatoli Karpov's amazing victory at Linares five years later.
