Part 1 of this 8 part chess rules course aims to teach about the board and the coordinates. Briefly, the chess pieces are mentioned; other parts cover the chess pieces in full details. The course aims to be a user-friendly, safe, commercial-free and motivating way to learn chess, step by step. Every course part exists of an explanation, followed by exercises. There is no exam, or track of score; it's perfectly ok to make as many errors as needed. Because of random selection of exercises, repetition may occur. Please be patient. Repitition is the mother of skill. Every part of the chess rules course is a separate app, which has been constructed with NativeScript technology (https://www.nativescript.org/). DISCLAIMER The chess rules course parts are in beta version state, for possibly unlimited time. Install might be unsuccessful. The first 2 free parts are a fairly good indicator that the technology in use will install and work for every course part on your device. All parts share exactly the same technology.
