PokerFingers is a web based tool designed for poker players who want to study and analyze hand histories. Its primary function is to allow users to replay and review poker hands, study hand ranges, calculate equity, and solve postflop scenarios. The tool also supports reviewing player statistics and provides the ability to import and export backups from Preflop+, a popular preflop range training application. The main features of PokerFingers include hand replay and analysis, range study and equity calculation, postflop spot solving, and player stat review. Users can work through specific hands to understand optimal play, examine how different ranges interact on various board textures, and evaluate the equity of their holdings against opponent ranges. The import and export functionality enables seamless integration with Preflop+ backups, allowing users to transfer their studied ranges between applications. Typical use cases involve a player reviewing a session by loading hand histories, stepping through each decision point, and using the solver to check whether their actions were theoretically sound. The tool can also be used to study specific postflop situations in isolation, such as a particular flop texture or turn card, to build a deeper understanding of range construction and bet sizing. Players may also use it to track and analyze opponent tendencies through the player stats feature. PokerFingers is accessible through a web browser at pokerfingers.com, requiring no installation beyond a modern browser. The tool is intended for poker players at various skill levels who wish to improve their game through systematic hand analysis and solver based study.
