Paco Ŝako (Esperanto for peace chess) is a form of chess created to be an expression of peace, friendship and collaboration. The aim is to find, through strategic gameplay, a way to "embrace" the other player's king.
Paco Ŝako is played on the same board and with the same chess pieces as traditional/classic chess, though the Paco Ŝako chess pieces have a different functionality. Black and white pieces can be merged into a union and can stay together on one square. Because there are no pieces taken, all pieces stay on the board during the game. Once unions are created, both players can still move them; you can take over a union and release your piece out of a union by replacing it with another piece and eventually there is the chain reaction, which really brings out the Paco Ŝako gameplay. Taking over unions and releasing pieces mean you may move several pieces in one turn.
In order to play you'll need two sets and a chess board with fields of about 5x5 cm each. You canc find a suiting chess board here.
