Spassky plays for a qualifikation place in the Interzonal in Portoroz 1958. The first four are qualified. With a win Spassky will share 3.-4. place with Bronsten. With a draw he will become 4.-6. with Averbakh and Gurgenidze. So Spassky plays 66 moves for a win. After getting a clear winning position after move 55..h5? he first did not realize his advantage and later blundered (67.g3?) with the result of loosing the game and the qualifiaktion for the interzonal.} Nf6 2. c4 e6 3.
