24143 - The intertemporal chess board

N. Lygeros
Translated from the Greek by Athena Kehagias

The intertemporal chess board is constituted by a medieval one, which is enclosed within two classical ones.
As a result its dimensions are 8×28.
The game is played by six players who play in groups of three per team.
Consequently, each team obtains one medieval and two conventional bases.
Everyone functions according to the rules of the local game, but has the right to play across the entire chessboard.
The three chess boards are joined linearly following the colouration of the squares which function alternately.
Each team obtains only one side of the board, and has three kings to its avail.
The aim of course is to checkmate all three opponents.
If checkmate has been imposed on a king, then his soldiers freeze and the others continue playing without him, until his release.
In regards to the medieval chess board, as the concept of stalemate doesn’t exist in this case, it is considered a stalemate when it can’t move.
In other words we merely follow the European rule of the fortress chess board.
The medieval board is situated in the center, because due to its rules, the playing of its pieces is slower compared to the conventional one, but simultaneously it is also bigger, a factor which gives opportunities of a wider range.
It is called the Temporal, because we simultaneously play upon it the rules of different eras, but with chessboards which obtain a time overlap.
Traditionally the white play first, and then alternately thereon, with each of the three-player team. The initial move is done by the player who is in the medieval chess board and it is continued with the two classical ones.
