Chess Coach Pro is an Android game that offers an immersive chess learning experience to players of all levels. The app provides various difficulty levels, chess puzzles, and practice modes to sharpen your skills and improve your gameplay.

One of the app's key features is the ability to play online with friends or accept/post a challenge on Free Internet Chess Server (FICS) servers. Users can also set the clock and try beating the computer in a given time or play classical chess without time. The app allows players to copy/paste the position to/from the clipboard, load and export PGN, set the board color and tiles theme of their choice, and supports PGN variations.

The app also offers a single-player mode, two-player mode, and the ability to edit the board to set a custom position for analysis or play. The "play" button allows the computer to move at any position, and users can undo/redo moves an unlimited number of times.

Overall, Chess Coach Pro is a comprehensive chess learning app that can help players of all levels improve their gameplay. Its ability to analyze games and find better alternative moves is an added bonus. However, it would be great if the app could provide more feedback on the player's moves to help them learn and improve further.
