ABSTRACT
In chess, style concerns the characteristics of one's knowledge and thinking that affect the kind of moves one chooses. Chess has been the main topic of study behind many ground-breaking works on intuition. Chess books tend to focus on three styles: psychological, positional and tactical. The combinational style focuses on direct attacks, drawing on tactical ideas to implement plans. In chess history, many players developed styles that were truly universal. Swiss psychologist Jean Piaget famously proposed in his theory of genetic epistemology that, with respect to knowledge, ontogeny parallels phylogeny. M. Guid and I. Bratko calculated the difference in quality between the move proposed by the computer programme and the move actually played in the game. Most computer programmes playing chess are based on powerful evaluation functions, combining dozens of features, such as safety of the king, mobility of the White-square bishop and control of centre, with the ability of searching billions of positions before selecting a move.
