Hello (zzo38) A. Black. Thanks for commenting. Yes, I just looked at your Communist Chess and then revisted my Doppelganger note from May of 2004. There I wrote: 'In the original game (the one that I awoke with) black pieces were doppelgangers relative to white pieces and visa versa. When you captured a piece both it and a matching one of yours was removed. Even promotions resulted in a promotion for your opponent.' It seems these rules would give us Communist Chess. My note continued: 'Material balance was maintained throughout the game, and it was very difficult to achieve victory. That game is a real workout and can be very frustrating. I changed the game so that each side had its own doppelgangers and by doing so created great opportunity for dynamic imbalance ... ' Anyway, I believe that you created the game independently. There are bound to be creative coincidences, especially considering the large number of variants that exist.
