Chequers was once Checkers, though those in the know called it Draughts, except for the American GIs who insisted on Chequers, though the Southern boys called it Drafts, it went upmarket for a while and was called Chess, but that didn't quite work as the rules were too complex, so they reached a compromise and called it Check, and that seemed like perfect marketing as it matched perfectly with the Aussie "Mate" (or Maaaaaate to the true blue), but CheckMate caused some copyright problems with a popular brand of condom at the time, so then it became The New Chequers, which went down about as well as The New Seekers, so then it was back to Chequers again.
So now its Chequers again and it's Back to the Future though not back to the Back Gammon, because the Backgammon is a totally different episode in the complex and convoluted history of Sydney's gaming and vice.
