This is a form of four-handed chess on a regular 8x8 chess board called Nava, which is sanskrit for new.
It is a chess variant invented in 2018 and is inspired by the ancient Chaturanga (resp. Chaturanji).
Nava is meant to be a team game. But it can also be played as everyone
It can be played by taking two sets of regular chess pieces and one regular chess board.
only five pieces in Nava. They correspond to chess pieces in almost every way.
King, bishop, rook, knight, pawn.
A king can
become a sixth character namely a queen in the game. He is considered a
king with special powers.
It moves and strikes as a queen in chess does.
takes one half of the pieces of one color of the two chess sets: the queen, the
king, the rook, the knight, the bishop and four pawns.
They are to be placed in a corner as shown in the picture below.
The queens are placed on the corners outside the board. So everyone sees which
army's color the corner is, even when all the pieces are gone.
The pieces move as in chess with little exceptions.
Any piece can take any piece. Also kings can be taken.
Friendly pieces can be taken if necessary. (In teamplay treason is possible but not welcome.)
There is no check in Nava.
There is no castle in Nava.
There is no en passant in Nava.
When a king is taken his entire army is taken over and led by his allied king.
The allied king now has a larger army but still has only one turn each round.
In an everyone against everyone situation the pieces stay on the board but can't move anymore.
They still can be taken.
players take turns clockwise.
The aim of the game is to take both kings of the two opponent teams. When both are taken, the game ends.
If there are any opposed kings left and they can't be beaten it is a draw.
Like in chess the players can surrender or declare draw at any time.
When a king
arrives the square of the four center squares which is the farest, looking from
his starting position, he becomes a divine warrior and changes into a queen.
There are no regular queens in this game.
When a king is promoted to a king, the king and queen swap places.
The king is now placed outside the board to mark the color of the corners army and the queen takes the kings' former place.
Pawns move in
two directions of both opponents. They move straight and take diagonally (as in chess), depending on what half of the board they are. When they are on the diagonal (looking from one team mate to the other) they are able to take in three diagonal directions. This is the only exception.
Once they reach one opposite edge of the board they are promoted.
Pawns promote to rook, bishop or knight once they reach the opposite last rank of the board.
The player leading the army can choose to what the pawn shall be promoted.
It can only be promoted to any piece that is left or available of the corresponding chess set.
Which means a player can't have more than two rooks, bishops or knights.
