He was also a renowned pianist in his home country. One of Djaja's studies was circulating during the Skopje Olympiad in 1972. It has become a famous study, especially since the position after Black's fourth move looks completely losing for White. I give here a version of 1976.

By playing the knight to this square on the edge of the board, White gains control over the squares f5, f7, g4 and g7. He needs to control these squares to set a mechanism in motion: perpetual check on the g-file. Black's rooks are tied to the a-file by White's a-pawn, and so the black king doesn't have any possibilities to escape. The Danish grandmaster Peter Heine Nielsen once said that this also worked with a bishop instead of a knight on h6. Also in that case, White controls the entire g-file.} 5... Rxa7 6. Rg7+ Ke6 7.
