Spy Chess: Genesis

New version of the game of chess. It would include a new element of play that would add unpredictability to the game, thus making it more challenging and exciting. Each player will pick 3 pieces of the opposite color, that is not the king. The other player does not know which of their pieces you picked. These are your spy’s. You will get ONE opportunity to reveal each spy. The piece you reveal turns into your color. You now control that piece for the rest of the game. Reveal your spy's wisely.
