Black is in trouble. White wants to play Re8, but then Black still holds with f5. However, there is a way to elaborate on this idea, which Spassky did not find. He played 21.g4 and won anyway. But can you find the real killer move in this position?

Upcoming Tuesday, Match 23, will mark 90 years since Viktor Korchnoi's birthday.

Korchnoi played this game against Robert Byrne at Sousse Interzonal in 1967. White just carelessly played 28. Qc3. Can you finish the game for the legend?
