What is the most queens that have been on the board in a grandmaster game?

Question

There are quite a few grandmaster games with 3 queens or 4 queens, but what is the highest number of queens on the board in a game between two GMs?

I'd be interested in both the most on the board at the same time and the most total during the game.

Answer 1

This sounds like a job for Tim Krabbé, who presents two games with six queens: Szalanczy - Nguyen, Budapest 2009 and Anton - Franco, XXI Elgoibar Magistral 2011. I don't know how many of the participants were grandmasters.

There are some other games with 5+ queens at Chess Siberia. Of these, Miton - Benjamin, World Open Philadelphia 2005 definitely features two grandmasters.

Answer 2

If you have a PGN file of chess games you can use CQL to search it. Something like:

(match
  :pgn src.pgn
  :output queens.pgn
  (position
    :piececount [Qq] 3 8))

Should return all games with positions containing 3 to 8 Queens on the board.

Edit: The Aquarium interface from chessok has a CQL search capability and can read ChessBase databases, so I was able to search my reference database (5M+ games) to games with 5 or more queens. There were no GM games with more than 5 queens on the board. The Anton Guijarro - Franco game mentioned by dfan, is a GM (Anton) vs an IM (Franco). In addition to the Miton - Benjamin game mentioned by dfan, I found a game played about a month later, Hickl - Sokolov that had 5 queens.

Answer 3

Using the more recent version of CQL, this is even simpler:

// Chess Q 12704
// find positions with many queens

cql(input Mega_Database_2022.pgn)

sort #[Qq] >= 5

Finds all games that have 5 or more queens on the board and sorts them by the amount found. A total of 49 games were returned when I ran the script against Mega Database 2022. 22 (!) of these were online, played in 2020-2021. Some were pretty ridiculous (with 7 queens on the board!). Here are some interesting ones between IMs/GMs:
