Patterns in Common- Znosko-Borovsky vs. Salwe, St. Petersbutg 1909, Spassky vs. Petrosian, 1966 WC
Browsing through Lasker's book about the St. Petersburg 1909 tournament, I came upon a position in the game Znosko-Borovsky vs. Salwe that reminded me of a win by Petrosian in his WC match with Spassky in 1966.
As you might know, many times openings transpose into other openings....in this case, also, the pawn chain in the centre, plus the position of White's bishop at f4 and the White pawns on e3 and e5 were common to both games, and in both cases, it favored Black!.....although in one of the games, Black castled long....
So, two different king locations, same pawn-piece structure, both favoring Black! I thought it is something worth remembering, from the positional point of view, and that led to the thought that it might be worth sharing it as well!
Notice the similarity in the structure, after move 11 in the Znosko-Borovsky game, and after move 12 in the Petrosian game.
So here we go! Enjoy!
