Russian draughts, duel

The goal of the game is to deprive the opponent of the opportunity to move by taking or locking all his checkers.

The game can be played with artificial intelligence, together with another person on the same device, or with a rival online in multiplayer mode. You can also watch other players' games, act as a spectator, and offer your own version of the player's next move by making it on the board.

Rules:

The player with the white checkers goes first.
A simple checker moves diagonally forward one square.
The queen moves diagonally to any free field, both forward and backward, but cannot jump over her checkers or queens.
Taking is mandatory.
A simple checker located next to the opponent's checker, behind which there is an empty field, is transferred through this checker to this free field. If it is possible to continue taking other opponent's checkers, then this capture continues until the striking checker reaches a position from which a fight is impossible. Taking a simple checker is done both forward and backward.
The queen hits diagonally, both forward and backward, and stands on any free field after the beaten checkers. Similarly, the queen can beat several opponent's pieces and must beat as long as possible.
When fighting through a queen's field, a simple checker turns into a queen and continues the fight according to the rules of the queen.
If there are several capture options, for example, one or two checkers, the player chooses the capture option at his discretion.

The game is considered won:
- if one of the opponents has beaten all the checkers;
- if one of the opponents' checkers and queens are immobilized, i.e. he is unable to make a move when it is his turn.;
