Introducing the Strong Chess Program, designed to challenge players of all skill levels with its 20 levels ranging from beginner to Grandmaster. This program is one of the strongest chess software ever created, incorporating all official Chess Rules, including draws by stalemate, insufficient material, the fifty move rule, and threefold repetition. For seasoned players, tackling the higher levels (16-20) offers a formidable challenge, while beginners can enhance their play stability, attention, and concentration by playing on levels 1-10.

Making a move is simple: touch a piece, and all available moves will be highlighted. Select one of the highlighted options to complete your move. If you wish to start a game against the computer from the initial position, navigate to "Computer" -> choose your level -> select your color -> and begin playing. For games starting from a specific position, set up the board, then go to "Computer" -> choose your level -> and play. If you want the computer to play both sides, set up the position, then go to "Computer" -> "BothSide" -> choose your level.
