user5784: I'm looking for the complete game Szabo-Groszpeter, Kecskemet 1984. The following knight endgame was reached and White won eventually with the paradoxal move Kb8!! blocking his b-pawn on b7.
[fen "8/K5p1/1p5k/1P5p/P1n5/5N2/8/8 w - - 0 1"]

1.Nd2 Nxd2 2.a5 bxa5 3.b6 Nf3 4.b7 Ne5 5.Kb8

I searched the complete game in various databases without success: chessgames.com, chess365 and chesstempo.

user11434: It looks like the game ended after a5. In Van Perlo's Endgame Tactics (Page 397 - ISBN 978-90-5691-494-3) it is described as following:"Here, at move 61, the game was interrupted, according to the rules applied at the time in the Hungarian Team Championship. The adjourned position was sent in for adjudication and the allgrandmasters committee declared the game a win for White."
He then give two main lines (main line with Kb8).
