MIRANDA, J et al. Observational analysis of illegal moves in grassroots chess: identifying difficulties in the understanding of the game. CPD [online]. 2019, vol.19, n.3, pp.90-101.  Epub 22-Jun-2020. ISSN 1989-5879.

Within the observational methodology, and based on a detailed analysis of FIDE laws of Chess, an observation system has been developed ad hoc for analyzing the illegal moves that children commit in chess. The reliability of the resulting data was confirmed by analysis of interobserver agreement, using Cohen's kbibra statistic. The results of the generalizability study confirmed the generalizability of results and the validity of the observation instrument. A Lag Sequential Analysis was performed to identify significant associations between categorical variables in each of the seven types of illegal movements characterized (castling, pinned, king to threatened square, incorrect movement of piece, promotion, occupation, do not remove check). The results obtained in the analysis of illegal movements, reveal the difficulties that the child (under 12 years of age) finds in the understanding and practice of chess.
