Relocation Chess is like standard chess except that the players can, before play begins, swap places of the king/queen and another piece except the rooks. Thus, if the king is swapped (relocated), the other piece (the relocatee) ends up on the king's square. If the queen is swapped, the relocatee ends up on the queen's square. One restriction is that the bishops mustn't end up on the same square colour. Note that black begins by making the initial swap. Alternatively he can choose to leave the position as it is (by pressing the king). The white player then has the option to relocate his king or queen, whereupon he starts the game by making the first move.

Note that the king retains his castling rights even if it has been relocated. The castling rules derive from Fischer Random Chess. White castles in the following way (the Black procedure is equivalent). When castling left (O-O-O) , the king moves to c1 and the rook moves to d1. When castling right (O-O) the king moves to g1 and the rook moves to f1. The following conditions must be true: the king must not move to, from or over an attacked square; the king and rook have never moved; there is no other piece on any square over which the king and rook move. Note! If the king starts the game on a castling destination square (c or g), castling on that side is done by moving the rook instead of the king.

Curtailed castling: as an alternative rule, the king may retain its castling right only if it is placed on any of the four central files. In other words, if the king is positioned on the g or b file, the castling right is forfeited. After all, such a safety move brings certain advantages so it should cost something. This restrictive rule would also enhance strategical predictability.
