Tigran Petrosian: The great defender goes on the attack against Tal in 1973.

The idea

The great defender goes on the attack against Tal in 1973.

  1. The pawn on c5 steps to c4 and hits the bishop on b3.
  2. If the bishop takes on c4, the knight takes the pawn on a4.
  3. Then the a-pawn is free to run at White’s king.

In a game: When the kings castle on opposite sides, push your pawns at the enemy king.

How the lesson begins

Tigran Petrosian was born in Tbilisi, Georgia, in 1929. He was famous for his defence: he saw his opponents’ plans early and stopped them before they could start. In 1963 he took the world title from Mikhail Botvinnik, kept it against Boris Spassky in 1966, and lost it to Spassky in 1969.

Here is a game from the USSR championship of 1973. Petrosian has Black against Mikhail Tal, and this time he is the one who attacks.
