A BIG Fischer Upset

 
     In all likelihood during the preliminary matches at the 1960 Olympiad in Leipzig when United States Champion and super Grandmaster Bobby Fischer sat down to play a mere National Master, an amateur and a recently graduated engineer with limited international tournament experience and no international title named Cesar Munoz Vicuna (1929–2000) from Ecuador, there was little cause for concern. 
     No doubt Fischer, his teammates and the spectators were expecting and easy win for Fischer especially since he had the white pieces. That's not to imply that Munoz was a "weak" player! 
     According to Chessmetrics estimated ratings, Fischer's rating (a little over 2700) put him in the world's top ten. Munoz' estimated rating of about 2486 didn't even put him in the world's top 200 rated players. Still, a rating just shy of 2500 meant Munoz was a pretty good player, probably near IM strength. 
     It's possible that Munoz and his teammates were not so pessimistic about his chances as everybody else. Remember, in those days there weren't any databases or even Informators, the renown Yugoslav books with about 600 games that were published twice a year. So, there was no way for Fischer to have known of two interesting previously played games by Munoz in which he had beaten Bent Larsen and Fredrik Olafsson in the Student World Team Championship in Iceland in 1957, or the draw he achieved against William Lombardy in the same event. The Ecuadorian master did have some impressive scalps! 
Cesar Munoz

     During the game, Fischer had to work hard in a very complicated game that he ended up losing. They say that as the game progressed more and more spectators and players approached the table and the silence was heavy. Fischer was described as pale when he resigned and signed the scoresheet. 
     Fischer had never lost against a Dragon although he had yielded one draw. Besides that, in the 1959 Interzonal at Portoroz, Fischer defeated Bent Larsen in a Dragon that was good enough to make it into My 60 Memorable Games. 
     Cesar Munoz had a relatively short chess career; it lasted from 1951 to 1969 when he abandoned chess to dedicate himself to other activities, namely President of the National Sports Federation of Ecuador and the Ecuadorian Olympic Committee, where he developed an excellent program. 
     In the following game Munoz adopted the Dragon Variation which at the time was considered highly questionable because of the Yugoslav Attack. At move 16 he put his Queen in a precarious position and before Fischer realized that he must proceed with caution, Munoz had obtained a winning attack.
