RI — Rules International CPI

 

«Problemism (herein defined as the composition of draughts problems) is a creative activity within and alongside the game of draughts. Problemism means/contains search of new ideas, analysis, analysis retrograde. The end product is a draughts position, which may or may not have occurred in a game, with a definite task. This position (and further positions passed through as the solution progresses) must satisfy certain rules.

During the history of problemism several types of problem have emerged. At the present time the two main types are Combination Problems (C-Problems) and Endgame problems (E-Problems)».
