This game was dubbed "White Key Symphony" by chessgames.com for the fact that Karpov made moves on only light squares for 18 moves in a row.

Is this still the record for the light squares, and what of the dark squares?

  • That's a good one for Chess Query Language... My guess : the defensive side in some opposite colored bishops endgame !

  • Are you interested about the games with the longest sequence (usually opposite-coloured bishops endgames) or just about interesting games with >18 consecutive moves on one color (e.g. where no bishop moved)? Sep 16, 2023 at 17:39
  • @double-beep Longest sequence of consecutive moves by a side on one color. Though bonus points for interesting games, I suppose. Sep 16, 2023 at 22:10

Thanks to this CQLi query:

cql(input Mega_Database_2023.pgn)

flipcolor {
    sort "Consecutive"
    line singlecolor 18 1000 nestban --> move to light . *
}

// check 3-fold repetition:
dictionary (min) $D
if initial then unbind $D

$appearances = 1
$key = zobristkey

if $D[$key] {
    $appearances = int($D[$key]) + 1
}

$D[$key] = str($appearances)

$appearances <= 2

which I ran against Mega Database 2023, I found some interesting stuff.

  • For the 20 moves examples, it is worth noting that your query considers Black's short-castle as a light-squared move. This sounds reasonnable to me, but someone may be surprised when they see the rook reaching f8...
