 Tibor Karolyi devoted a chapter to him in his 2009 book "Genius in the Background" and jokingly called him "Kasparov's Half-Brother", as Kasparov and Nadanian were both coached by Alexander Shakarov, and there were similarities in their playing styles.In particular, Karolyi emphasizes their ability to implement effective ideas on the edge of the board, attributing this to the influence of their common chess "father".As an example of flank pawn advances versus a solid centre, John L. Watson in his 2003 book "Chess Strategy in Action" brings attention to the game Nadanian – Ponomariov, Kiev 1997 and calls it "almost satire on rule-breaking", as nine of White's first thirteen moves have been pawn moves and only one of those has been with a central pawn, yet Black's position was extremely difficult.
