gm Sax,Gyula
Galeb, Antoine
Skopje Olympiad, 1972. Position before Black’s 16th move. Strategically the game is very interesting, but there is a tactic hidden that White did not sense when he played his last move.
HOW DOES BLACK GET A BIG EDGE?

gm Sax,Gyula
Polgar, Istvan
Hungary, 1970. A sharp game! Sax had just played 24…Nxg2!. The Knight can not be taken because of 25…f5!, and moving the Rook (25.R1-e2) is also met by …f5 with a big edge. From the position above…
HOW DOES WHITE SAVE HIMSELF?

Skopje Ol 1972 Galeb Antoine–Sax Gyula:16… Rxc3! This wins two pieces for a Rook and also gives Black a dominating position. 17.Qxc3 Ne4 18.Qe3 f6 19.Bh6 Bxh6 20.Qxh6 fxe5 21.dxe5 and now simply 21…Qc7 would have won quickly.
Hungary, 1970. Polgar Istvan–Sax Gyula: 25.Rg4!! Nxe1 26.Rxg7+! Taking the Rook allows perpetual check . Instead, Sax wanted more and lost trying with 26… Kh8? 27.Qh6! Qe4 28.Rg4 Qg6 29.Rxg6 Nf3+ 30.Nxf3 1-0
