Life and chess composition:

Nenad Petrović is one of the greatest composers in chess of all time.

Over the years, he has published over 650 original works from all areas of chess composition, 121 of which have been included in the FIDE albums! For his outstanding achievements, he was awarded the title of Grand Master of Chess Composition in 1976. His numerous records, some of which are still valid today, as well as the tasks he devised and realised, set new standards in chess composition and earned him the title "the man of tasks".

As early as 1947, he became world champion in solving chess tasks. In 1952, he founded the specialist journal Problem, which established itself as the official mouthpiece of the Permanent Commission for Chess Composition at FIDE (PCCC) from 1959 until it was discontinued in 1981. In 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 Compositions and launched the FIDE Albums at the Piran Congress in 1958, the first 13 editions of which, covering the period from 1914 to 1982, he played a leading role in. He was unable to complete work on the 14th album due to his death.

As an international adjudicator, Nenad Petrović organised countless tournaments. He also wrote many articles in which Petrović presented pioneering ideas on chess composition.

Nenad Petrović also dealt with lesser-known areas of chess composition such as chess mathematics and construction problems:

How many different chess games are theoretically possible? In 1948, Petrović gave the number 1018900.
With all 32 pieces you can build about 1032 legal positions.
Place all the 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 moves.
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.

He was  International Master of the FIDE for chess composition since 1965.

He was International Judge of the FIDE for chess compositions since 1956.

 He mainly composed Chess Problems but also a few studies.

Nenad Petrović composed more than 650 problems in all genres.
He was also an International Judge, the President of the 'Problems' section of FIDE from 1958 to 1964.
He was the founder of "Problem", the magazine of this section, which he directed from 1951 until its last issue in 1981,
the problems editor of the magazine "Sahovski vjesnik" from 1951 until 1959,
and the author of a book dedicated to chess composition, "Sahovski problem".
