Polish defence by Spassky

Very pretty set up by White!

c5 restraint

A lot of central pawn tension

Spassky avoids a repetition draw given the match score

Very aggressive play by Spassky

Petrosian has attacking pressure

Final position 35 Nf3 black resigns - Why was it hopeless for black?

What if Scenarios - if the game continued with Bxd4

Theoretical continuation - Undoubling of White's pawns

Theoretical continuation - A crushing tactic Bxf7+

Theoretical continuation - Rxd7+

Theoretical continuation - The power of a double check

Theoretical mate finish

Key takeaway points

• c5 restraint was instructive and probably very frustrating for a dynamic aggressive player like Boris Spassky - Petrosian has a habit of getting players to damage their own positions to create some sort of counterplay
• Sometimes players have to play the match situation rather than the board position - Spassky avoided a repetition but his position was compromised
• The theoretical continuation shows the power of a rook on the 7th rank
• The theoretical continuation shows the power of a double check
