33.Qxh6!
A spectacular blow by the legendary Bobby Fischer, the eleventh World Champion, and one which
ends the game. In addition to 34.Qxh8+, followed by checkmate, Fischer threatens 34.Qxe6.

The key to the combination is that if 33...Rxh6 then 34.Rb8+ Nxb8 35.Rxb8++, while if the rook
moves away with 33...Re8, apparently defending the bishop on e6, the protection proves illusory
when White plays 34.Qxe6 anyway, since 34...Rxe6 allows the same mate on b8.

It was easy. Do I get extra points for knowing it is from the game Fischer-Weinstein 1960?

30.Qh8+!!

Black resigned, in view of 30...Kxh8 31.Nxf7+ and Nxg5, with an extra piece.

This was the finish of a game which is considered the best of the first match for the world title
between these two world champions.

In this match, their first, in 1966, Petrosian retained his title, but in their 1969 match the winner was
Spassky.

White To Move
Solution .. Spoiler Below



The seventh World Champion, Mikhail Tal, has sacrificed a piece to reach this position. Although
the rook on c4 is under attack, the black queen is the only obstacle to carrying out a lethal discovered
check from the white queen by moving the rook from f5.

So all that’s necessary is to displace the queen from e6.

29.Re4!
A decisive blow; now if 29...Qxe4 then 30.Re5+, winning the queen.
29...Qxa2
16
Now the result is mate.
30.Rxc5+!
If 30...Kd6 then 31.Rd4+, followed by mate, while if 30...Kd8 White captures the rook on c8 with
mate.
1–0
