19.Rxf6!! A prelude to the combination to win material.

19...Bxf6 20.Nf5!!
Changing of guards. The knight makes the square g3 available to the pawn.

20...gxf5 21.g3!
The final point. The Queen seems trapped. There is only one way to save it.

A desperation. but other moves do not help. [21...Qh3? 22.Nxf6+ Kf7 23.Bf1!+- ; 21...Qg5 22.Bxg5 Bxg5 23.Qe2+- ]

22.bxc3 Qd8 23.exf5 Ng7
[23...Nf8 24.Bg5! Qa5 25.Bf6!+- ; 23...Qf8 24.Bh6 Qf7 25.fxe6 Bxe6 26.Nc7!+- ]

[The computers find a different path: 24.f6 Ne6 and now: 25.Bh6 (25.Ne7+ Kf7 (25...Kh8 26.Bh6+- ) 26.Qe2 Kxf6 27.Nd5+ Kg7 28.Qh5 Qg8 29.Ne7+- ) 25...Qe8 26.Ne7+ Kf7 (26...Kh8 27.Bg7+ Nxg7 28.Qh6 Nf5 29.Bxf5 Qf7 30.Bg6+- ) 27.Qe2! Kxf6 28.Nd5+ Kf7 29.Qf3++- ]

24...Qf8 25.Nf6+ Kh8 26.Nxd7
Game over, but Matulovic was know to make a few unnecessary moves.

26...Qf7 27.Nf6 Nh5 28.Nxh5 Qxh5 29.Bf6+ Kg8 30.Be4 h6 31.Qxd6 Re8 32.Bd5+
