Bobby Fischer’s Chess Tactics!

The position below is from the game:
Fischer, Robert J (2690) vs Shocron, Ruben (2280), 1959, Mar del Plata ARG

Black just played 39… Qc8. It seems Fischer fell into a trap since his rook on e6 is now pinned. What should white do?

It appears that black will simply capture the white rook on the next move. However, Fischer anticipated this move and had a brilliant response ready! Can you find it?

Bobby Fischer Tactics – The Solution


Bobby Fischer’s chess tactic demonstrates a number of important tactical ideas at once.

  • Threat / winning a tempo
  • Interference
  • Indirectly defended square
  • Hanging piece
  • Discovered check

I’ll explain them all below:

Threat / winning a tempo

40.Bd7 threatens to capture the black queen. This means black’s options are limited to moves that sufficiently deal with this threat. However, the threat alone is not enough. This move must be supported with other tactical ideas else black can simply capture the bishop, Qxd7.


40.Bd7 interferes with the pin black had on the white rook. The white bishop occupies the d7-square and therefore the rook on e6 is technically not pinned anymore.

Indirectly defended square

At a first glance it appears that the white bishop is undefended on d7. However, the d7-square is indirectly defended. If black plays 40… Qxd7, then white can reveal a discovered attack, 41.Rxg6+, followed by 42.Qxd7.

Discovered Attack

The diagram shows that if black plays 40…Qxd7, then white can play 41.Rxg6+, followed by 42.Qxd7.

Hanging Piece

In the initial position (before white played 40.Bd7) the black queen is defended by the black rook on b8. This means white’s discovered attack, Rxg6+, does not work yet. However, if after 40.Bd7 black plays 40… Qxd7, then the black queen would be hanging (undefended) on d7. This is an important detail because then the discovered attack, 41.Rxg6+, followed by 42.Qxd7, works.
