- Watch whether Black's a5-knight creates pressure on c4 or finds the b7-d8 route home.
- Compare Black's queenside plan with the later commitment to a kingside pawn storm.
- Notice how Petrosian invites complications only after judging which black pieces can participate.
Coach
Mikhail Tal annotated this game soon after it was played. His central thread is not a computer evaluation but a human strategic question: once Black's knight goes to a5, will it justify itself on c4 or find a route back before the kingside battle begins?
