Abstract

In Chase and Simon's (1973b) pattern recognition theory, quantitative differences in knowledge (size and number of chunks) were considered to determine skill differences between chess experts and novices. In addition, Holding's (1985) SEEK (Search, EvaluatE, and Know) model also included differences in search and evaluation. The present study dealt simultaneously with all three components of the SEEK model. Fifty-three chess players of five different levels of expertise sorted two sets of 30 chess positions according to their own criteria. Written descriptions of the sorting criteria used were analysed. The dynamic aspects arising were captured as well as evaluative statements, and chess knowledge. With increasing level of expertise, an increase in relevance of all three components was shown
