A Kraków academic has developed a new way of playing chess after using lockdown to analyse Russian troops near the Polish border.
Zbigniew Kokosiński from the Kraków University of Technology was using his traditional chessboard to arrange the pieces to depict a metaphor for Moscow’s military forces in the Russian region of Kaliningrad when he came across his new method.
Instead of being arranged on opposite sides of the board, in two rows, the pieces are placed in two opposite corners. The two kings are put right in the corner, followed by the other pieces and he pawns are placed the further away from the corner, facing each other diagonally, making the game more challenging than traditional chess.
Kokosiński said: “The king is protected by four lines of defence (in traditional chess only by one row of pieces) and you cannot checkmate immediately.
“It is necessary to fight your way to the opponent’s king. “In diagonal chess a novice player can be an almost equal partner of someone experienced.
“Since knowing the openings does not give you an advantage, the ability to think logically is what counts.”
The new variation has now been entered onto the Chess Variant Pages website.
