Although standardised rules to govern international competitive chess had begun to be codified by the mid 19th century, the question of timed play remained a vexing issue with sand timer and other improvised methods proving manifestly inadequate. It would not be until 1883 in England that a timing device analogous to the modern chess clock was devised. This triumph of Victorian ingenuity effectively eliminated the blight of cogitating players consuming exhorbitant amounts of time in deciding their moves—finally the fight would be fair while sparing all from exhaustion.
