Hidden Chinese Chess - An Qi

Hidden Chinese Chess is played as a standard Dark Chess / Banqi game, which in itself is a more informal variation of Chinese chess. It is played in the middle of a Chinese chess board with pieces placed inside the squares (instead of in the corners as in Chinese chess) facing down. Each player takes a turn to flip a piece, with any colored piece discovered to be that player's team. The pieces that are uncovered move one square each in the four cardinal directions (except for the cannons) to move or capture other pieces. Each player continues to discover pieces and tries to remove all of the opponent's pieces or capture the last piece.
