OK, so here we all play chess. There are also many variations of this game...have you ever played "Ficsherandom chess", invented by the great Bobby Ficsher? It's a version in which the back rank pieces are shuffled in a random order, so players can't rely on their knowledge of opening lines.
In a Japanese version of chess, captured pieces are allowed back on the board. In Chinese chess, the pieces are placed on lines rather than spaces and squares, and a "river" separates the two sides in the middle. And, in another version, players choose at the start of the game where they wish to place their pieces. There is also "3-D Chess", which has made several appearances in the movie Star Trek.
Try all these variations of chess and see which one you like best!!!
