ChessPlayers 2021

A dataset containing information on Russian chess players was compiled in 2021 based on official rating tables. The breach involves structured data including full names, regional identification codes, unique player IDs, and performance metrics based on the Elo rating system. While the primary data source appears to be public or semi-public rating lists, the aggregation of these records into a single database allows for detailed profiling of sports participants across various regions of Russia.
