Modern chess. Prime Minister is placed to the left of the King.

Modern chess is a chess variant played on a 9x9 board. The game was invented by Gabriel Vicente Maura in 1965. First match was played in Madrid at Escuela de Bellas Artes de San Fernando's cafe on march 18 1968. The players were Gabriel Vicente Maura himself, whites, and Bonifacio Pedraz Cabezas, blacks.

Besides the usual set of chess pieces, each player has an additional piece with a corresponding pawn:

• a Prime Minister that moves as both a bishop and a knight.

Otherwise, the standard rules of chess still apply, with the objective being to checkmate the opponent's king. The king piece must be moved out of check when it is placed in check. If escape is not possible, the game is lost. A player still may resign at any point in the game, and en passant is legal.
