I learn how all the pieces on chess board work and use them well and learn the main stratergy in chess is every move to take you have to have everything plan out otherwise you make a move for nothing and every move is important. Also I practice online with other people.I pratice offline and online and learn new strategy also how to protect our pieces. Watch video about the mistake that people make. Pratic online and try to play trap that I learn but, it not work with the players that I played with.
