Answers.Body: <p>This sounds like a job for <a href="http://timkr.home.xs4all.nl/records/records.htm#Most%20queens">Tim Krabbé</a>, 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.</p>
  
  <p>There are some other games with 5+ queens at <a href="http://www.chessib.com/five-six-queens-chess-games.html">Chess Siberia</a>. Of these, <a href="http://www.chessgames.com/perl/chessgame?gid=1667656">Miton - Benjamin</a>, World Open Philadelphia 2005 definitely features two grandmasters.</p>

Answers.Body: <p>If you have a PGN file of chess games you can use <a href="https://web.archive.org/web/20140130143815/http://www.rbnn.com/cql/" rel="nofollow noreferrer">CQL</a> to search it. Something like:</p>
  <pre><code>(match
    :pgn src.pgn
    :output queens.pgn
    (position
      :piececount [Qq] 3 8))
  </code></pre>
  <p>Should return all games with positions containing 3 to 8 Queens on the board.</p>
  <p><strong>Edit:</strong> 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.</p>

Answers.Body: <p>Using the more recent version of <a href="http://www.gadycosteff.com/cql" rel="nofollow noreferrer">CQL</a>, this is even simpler:</p>
  <pre><code>// Chess Q 12704
  // find positions with many queens

  sort #[Qq] &gt;= 5

  <p>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:</p>

  This sounds like a job for [Tim Krabbé](http://timkr.home.xs4all.nl/records/records.htm#Most%20queens), 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](http://www.chessib.com/five-six-queens-chess-games.html). Of these, [Miton - Benjamin](http://www.chessgames.com/perl/chessgame?gid=1667656), World Open Philadelphia 2005 definitely features two grandmasters.

  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 username_1, is a GM (Anton) vs an IM (Franco). In addition to the Miton - Benjamin game mentioned by username_1, I found a game played about a month later, Hickl - Sokolov that had 5 queens.

  ### Answer by username_4 on 2022-01-07. Score: 0
  
  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:
