About this app
The application offers solving chess problems, divided into sections by openings and their variations or types of tactical techniques. The goal of each task is to find a combination to mate the king, achieve an advantage, and win pieces. In most sections of the application, after solving each problem, you can see the entire chess game from which the position was obtained.
