Introducing the Strong Chess Program, designed to challenge and enhance your chess skills across 20 distinct levels, ranging from beginner to Grandmaster. This program is renowned as one of the strongest chess engines available, fully implementing all official Chess Rules. Whether you're aiming for a draw by stalemate, insufficient material, the fifty-move rule, or threefold repetition, our program recognizes them all. For those who consider themselves strong players, tackling levels 16-20 offers a formidable challenge. Conversely, if you're a beginner looking to boost your gameplay, focus on levels 1-10 to improve your stability, attention, and concentration.

Making a move is simple: touch a piece, and all available moves will be highlighted. Select one of the highlighted moves to proceed. To start a game against the computer from the initial position, navigate to "Computer," choose your desired level, select your color, and begin playing. If you wish to start from a specific position, set up the board, then go to "Computer," select your level, and play. For those interested in seeing the computer play both sides, set up your position, go to "Computer," tap "BothSide," and choose your level.

Enhance your skills further by solving over 460 Chess Puzzles. A single click on ads will unlock three Chess Puzzles, and interacting with ads will also enable move hints and the ability to undo moves, perfect for learning. If you prefer an ad-free experience, consider installing the paid version of Deep Chess.

For in-depth game analysis, first enter your game by moving for both sides, then tap the "Reset" button, save your game, load it back, and use the "Hint" button, which is enabled by clicking on ads.

Our program now supports PolyGlot(.bin) opening books. To utilize this feature, ensure your SD Card is mounted on your device and download the PolyGlot(.bin) book to your Downloads or Documents folder on the SD Card. To add the book, tap the "Files" button, then "Add Book," and select your book. We highly recommend using this option for faster gameplay, especially on higher levels.

You can also export your saved games as PGN files to the Downloads folder on your SD Card. Achieve milestones and earn badges with our achievement system: secure 3 wins on the same level to earn a Bronze Star, 5 wins for a Silver Star, and 7 wins for a prestigious Gold Star.
