What if we'll add new rules based on the concepts of quantum mechanics to chess? There answer is: playing chess has never been so interesting!Is it possible put in check to the king, which is alive and dead at the same time (hello, Schrdinger's cat)? The only way to win the game: you have to destroy the opponent's king.The main introduction: all pieces except pawns can make "quantum move". For example, the bishop can move twice in one turn, but it will be in a superposition - it will exist and not exist on the two cells at the same time, and neither you nor your opponent will not know for sure where is the piece actually.How to capture this bishop?Here is the most interesting. You can attack one of the cells to take piece by non quantum move. But with 50 percent chance you'll attack an empty cell, and the real bishop will exist on the other cell.Classic strategies will not work in Quantum Chess, you have to come up with new ones.The game improves an intellect and trains to think several steps ahead.No need to be Stephen Hawking to figure out. Everyone can play in Quantum Chess!
