In this article, we will explain what HRC is, what are the benefits of using it, what are the main features of HRC, and how to use it effectively. We will also compare the two versions of HRC, Classic and Pro, and help you choose the right product for your poker needs. By the end of this article, you will have a clear idea of how HRC can help you improve your poker skills and achieve your poker goals.

What is HoldemResources Calculator (HRC)?

HoldemResources Calculator (HRC) is a software tool that calculates optimal preflop strategies for NLHE tournaments based on the Independent Chip Model (ICM) and Future Game Simulation (FGS). ICM is a mathematical model that assigns a monetary value to each player's stack based on their probability of finishing in each position. FGS is an advanced technique that accounts for future scenarios that may affect the optimal strategy.

HRC allows you to import hand histories from various poker sites and run calculations for different situations, such as push/fold, 3-bet, 4-bet, multi-way pots, etc. You can also adjust various parameters, such as stack sizes, blinds, antes, payouts, ranges, etc. HRC then shows you the optimal strategy for each player in terms of equity, EV, Nash ranges, etc. You can also compare different strategies and see how they affect your results.

HRC is not only a calculator but also a learning tool that helps you understand the theory behind preflop strategy and apply it to your game. You can use HRC to study common spots, review your sessions, find leaks in your game, test new ideas, and experiment with different scenarios. HRC also provides various web-based tools that you can use for free without downloading anything.
