Simple Preflop Holdem is a poker solver designed for preflop analysis in Texas Hold’em. It calculates optimal strategies for a specified betting tree and input ranges for 2 to 10 players across various preflop scenarios. The program performs local preflop calculations for different poker disciplines, supporting both ChipEV and ICM models, with rake considerations. It displays comprehensive data—including strategy, EV, and equity—for every hand and action. Leveraging full CPU power through parallelization, it ensures fast computation while using abstractions to reduce RAM requirements. Note that while Simple Preflop Holdem runs on Windows, MacOS users can operate it via virtualization solutions like Parallels or Bootcamp.
