The opening variations in chess

King’s Indian, Caro-Kann, Sicilian, these are the names of known chess openings. Here we will show how they work. The main variations of the openings have been played for hundreds of years. However, there is something new every day. In grandmaster tournaments we are constantly seeing new moves, the so-called innovations, Players research and analyse such innovations in their preparation at home.

The openings are sub-divided into five rough groups defined by the first move played by White and by Black. Each of these sub-divisions is subject to fashion and invariably becomes outdated. Nevertheless the structure which follows has remained even if the weightings tend to represent the opening fashions of 100 years ago:
