Thank you all for the comments!
ResponderExcluir1. Qh6+! is the key move, which Boris Spassky played in the actual game.
Possible continuations:
1. Qh6+! Kxh6
2. Rh1#
1. Qh6+! Kg8
2. Rc8+ Rf8
3. Rxf8#
1. Qh6+! Kg8
2. Rc8+! Rf8
3. Qg7#
Then, it's indeed a "mate in 3". :)

What you think about this series of moves?
He can move Kh8 and this delay the mate to 4 moves.
ResponderExcluirExactly, Dejanu:
ResponderExcluir1. Qh6+! Kg8
2. Qxg6+ Kh8
3. Rh1+ Rh7
4. Qxh7#
As shown before, 2. Rc8+! leads to a faster checkmate. :)
