Chess is a classic strategy game that has been played for centuries. It is a board game that requires players to use their logic and critical thinking skills to outmaneuver their opponent. The game is played with six different types of pieces, each with its own unique moves and abilities. The goal of the game is to checkmate the other player's king, which means putting their king in a position where it cannot escape capture.<br/><br/>To help players of all levels enjoy the game, an application has been created that offers ten levels of difficulty, chess puzzles, a game assistant, and the ability to undo moves and receive hints. The app also features seven different themes, two board views, and realistic graphics. Additionally, there is an alternate mode and a two-player mode for those who want to play with a friend.<br/><br/>Two special moves in chess are castling and en passant. Castling is a double move performed by the king and the rook that never moved, while en passant is a move in which a pawn can take an opponent's pawn if it jumps over a field under the pawn's blow. There are also three important chess situations to be aware of: check, checkmate, and stalemate.<br/><br/>Overall, this app is a great way to learn and enjoy the game of chess. With its various features and levels of difficulty, players of all skill levels can improve their game and have fun while doing it. Feedback and suggestions are welcome to help improve the quality of the application.
