Chess is a strategy game that requires the use of various cognitive processes. Chess players, through the extensive experience of chess parties and positions, develop schemes that enable effectiveness, quick recognition and problem-solving. Due to their great experience, it is being studied on how chess players become more rigid when making decisions because they're guided by previous experience. One of such effects is the Einstellung effect. It occurs when the first idea, based on previous experience and which appears because of the familiar features of the problem, blocks the insight of the optimal solution in the situation. In order to reduce such an effect, it is necessary to use more flexible methods in processes of solving Einstellung problems. The aim of the research was to investigate whether the factor of the reverse perspective influences the flexibility of thinking in chess. Club players (N=26) participated in the survey with a national chess rating score, they were solving a series of chess problems in which was determined the appearance of the Einstellung effect. The matter of interest was to notice the influence of the conventional and reverse perspective on the appearance of the effect. The greater frequency of non-optimal solutions and prolonged glance on the squares that are relevant for Einstellung effect indicate affection of the effect. Data analysis, provided on the results of solving time, confidence, and time and number of fixations on the squares relevant for Einstellung effect, determined that factor of reverse perspective was not significant. It has been shown that high-ranking participants have score better success and confidence, lower solving time, and lower time and number of square fixation. Despite the lack of expected effect, the research provides insight into the very issues and ideas for further research of this kind.
