发明名称 Chess to the second power
摘要 An improved chess-like game. The game uses a traditional chess board and basically the same rules. The additional second set of pieces and some rule changes enhances the game. There's a time limit to strategically place the secondary pieces inside of the primary pieces and placed on the board. Primary pieces for each player are the same as traditional chess. Secondary pieces include the same pieces as traditional chess except there is no king. When a primary piece is taken it is removed from the game, the secondary piece is removed from the primary then placed in the same square it was occupying with its primary piece. The piece that took the primary piece returns to the square it was in before advancing. Castling is the same. Using En passant, all pawns can be taken. Only primary pawns have the option of moving two squares on the first move.
