Polugaevsky- Bronstein: Queen vs Two Rooks!

Two days ago, on Jan. 7, 2020, GM Serper published a brilliant article about battles between Queen vs. Two Rooks.

He points to three elements that can be decisive in such a battle:

1) King Safety

2) Coordination of the Rooks

3) Passed Pawns

In the following game, played between Lev Polugaevsky and David Bronstein at the 34th USSR Championship (1966/67), the battle encompassed the whole board. Bronstein (Black( defended the Tarrasch Defense in the Queen's Gambit Declined. In the early middlegame, he allowed White to open the position with e4, in order to gain some space on the Queenside. After some maneuvers, a small combination ensued which left the following balance: White had two rooks against Queen and pawn.

Now, this game was played in the Winter of 1967, specifically January 30, 1966. At that time, games were still adjourned!

I will comment on the game, and add Polugaevsky's comments (in his book, Grandmaster Preparation, his comments start at move 41).

By the way, Polugaevsky and Bronstein shared 8th-9th places.
