Chessgames.com Chess Event Description
Amsterdam IBM (1975)

"The Dutch organizers usually look for top players, or at least players with fighting spirit. Their selection for this year's grandmaster group at the 15th IBM tournament was extremely successful, for I have not seen such interesting chess played at the IBM in years. Ljubomir Ljubojevic, the main contender for first prize, was expected to create fireworks. So was Jan Timman. Laszlo Szabo could easily have kept up the sharp pace; and I did not intend to remain in the shadows. Both Jan Smejkal and Robert Huebner, players with a fine positional feeling, good technique, and a belief in active defense, were expected to bring more objectivity to the battles. Wolfgang Uhlmann could have played either way, while the less-known Soviet players, Razuvaev and Makarichev, and the Dane Hamman, were expected to add an exotic flavor to the tournament because of their unfamiliarity. Gena Sosonko, Vlastimil Jansa, and Florin Gheorghiu are generally difficult to beat because of their solid routine. Hans Ree ... Well, he can play well and he can play badly, apparently depending on the weather. And Vladimir Raicevic and Hans Bohm were classed as tailenders. Someone at the opening ceremony even asked who they were. ...

Ljubomir Ljubojevic, try as he might, could not score the way he wanted to in the first ten rounds. He lost a few and won a few and had a score of 50%. But in the last five rounds he scored a fantastic 4½ points (winning the last three) and moved from seventh place to clear first. Now the IBM tournament has been added to the first prize he won earlier this year at the strong Las Palmas tournament. IBM was Category 11, with an average rating of 2510. What makes Ljubojevic so successful? To begin with, from his games one can see that he does not study the openings very much; he is, however, a master of improvisation, always trying to create extraordinary positions where his feeling lor sharp tactical solutions dominates the play. He likes to take risks and lets nothing stand in his way; in fact, in this respect he goes further than "common sense" would allow. He has been compared to the young Tal, and takes the same tactical path as his Yugoslavian colleagues, Velimirovic and Planinc." (Kavalek in Chess Life)
