The game begins with the distribution of cards depicting chess pieces that are eliminated from the game of chess, and an analytical assessment of the resulting chess position on the board. If a player receives a king card, then the king is not eliminated from the game of chess. The distribution of cards takes place 4 times. First, there are 2 cards for each player, separately for black and for white chess pieces. You only see your cards. You don't see the opponent's card. Next, three cards are distributed - they are visible to both opponents. There are 4 distributions in total, which result in the elimination of 6 to 7 pieces for each player. After the distribution of cards is completed, a position is formed on the board and a chess game begins with a time control of 3 minutes + 2 seconds per move according to standard chess rules. The following situations are considered a victory: checkmate win; time win; opponent surrendered; draw = black wins. Features: еach game will be unique due to the appearance and playing of a random chess position, which, under certain scenarios, gives beginners the opportunity to face chess professionals and makes each game intriguing and exciting.
