Game descripton from the author:

While it is just a chess game, I was getting a bit tired of the custom of just putting DS before or after everything, but if you want, just think of it as ChessDs.

The main change I’ve made to make between this and chess however, is that you don’t get checkmate to win, instead, the goal is just to take the opponent’s king.
