Life

Nenad Petrović is one of the greatest composers of all time. Over the years he has published over 650 originals from all areas of chess composition, 121 of which were included in FIDE albums . In 1976 he was awarded the title of Grand Master in Chess Composition for his outstanding achievements . His numerous records, some of which are still valid today, as well as the tasks he devised or realized , set new standards in chess composition and earned him the name of the man of tasks .

In 1947 he became world champion in solving chess problems. In 1952 he started the journal Problem , which from 1959 until it was closed in 1981 established itself as the official mouthpiece of the Standing Commission for Chess Composition at FIDE ( PCCC ) . 1956 Petrović was a founding member and from 1958 to 1962 president of the PCCC after the death of his predecessor J. Neukomm. He is also regarded as the spiritual father of the Code of Chess Composition and initiated the FIDE albums at the 1958 congress in Piran , and played a leading role in the 13 first editions for the period from 1914 to 1982. He could not finish the work on the 14th album due to his death.

As an international judge, Petrović judged countless tournaments. He also wrote many articles in which Petrović presented trend-setting thoughts on chess composition.

Petrović also dealt with lesser-known areas of chess composition such as chess mathematics and construction tasks .

  • How many different chess games are theoretically possible? In 1948 Petrović gave the number 10 18,900 .
  • With all 32 stones you can build about 10 32 legal positions.
  • Place all white pieces on the chessboard in such a way that a legal position is created and that White can make as many moves as possible. Here Petrović found a solution with 122 trains.
  • Construct a legal position in which White can make as many moves as possible. In 1964, Petrović constructed a position with 218 possible moves for White.
