vis-a-vis chess

Rules

Here are its main differences from classical chess:

1. The goal of the game is not a checkmate, but a rapprochement with the opponent's king on any adjacent squares, but only on the opponent's half of the board. Therefore, if the kings meet on their half of the board, then this is a defeat.
2. If the faced kings are on different horizontal halves of the board (on the fourth and fifth rankings), then this is a draw.
3. Check is possible in the game, from which the king is obliged to defend himself in one of the usual three ways - this is the retreat by the king, the covering of the king, or the capture of the attacking piece by the king or his other piece.
4. It is not allowed to checkmate the king or create a stalemate; the king should always have the opportunity to move.
5. When approaching the opponent's king, the king cannot enter check.
