The Impact of Lichess Application Usage on Enhancing the Tactical Skills of Chess Athletes

Abstract

In the digital era, chess training has transcended traditional boundaries through the integration of online platforms such as Lichess. This study investigates the effect of using the Lichess application on improving the tactical skills of young Indonesian chess athletes. Employing a quantitative method supported by qualitative data, the study involves 50 respondents aged 15–25 who actively use Lichess for self-training. Data were collected through questionnaires, analysis of game statistics from Lichess, and in-depth interviews. The results reveal a strong positive correlation between the frequency and duration of Lichess usage and increased tactical skill levels, as measured by accuracy scores and puzzle ratings. In particular, the puzzle tactic feature was found to contribute significantly to players’ decision-making abilities. The study concludes that Lichess serves not only as a digital game platform but also as an effective self-directed learning tool. Nonetheless, a hybrid approach that integrates face-to-face coaching with digital practice is recommended to optimize strategic understanding. This research contributes to the broader discourse on digital learning tools in cognitive sports and offers practical insights for coaches, institutions, and chess communities
