Why We Built CaptainRiver
The hard part of a hand is not only asking, "What do I have?" It is asking, "What can my opponent have?", "How did this board change the range?", and "Is this action supported by equity and price?" CaptainRiver turns those questions into visible, repeatable steps for review and training.
Core Capabilities
Build preflop ranges with a 13x13 matrix or Short Deck adapted layout. Save custom ranges and organize range libraries for repeated study sessions.
Estimate equity for hand vs. hand, hand vs. range, and range vs. range scenarios, giving each decision a clearer numerical reference.
Support for Texas Hold'em, 6+ Short Deck, and Omaha Hold'em, with inputs and calculations adjusted for each deck and hole-card structure.
Use M value tools and range advice entry points to reason more quickly about stack pressure, blind cost, position, and tournament decisions.
Who It Is For
CaptainRiver is useful for players learning poker math and for more advanced players who want to review opponent ranges, board texture, and action lines with more precision. Whether you are checking one hand or building a long-term range library, it is designed to be a calm, direct analysis desk.
Our Principle
We do not promise to make decisions for you, and we do not encourage copying numbers mechanically. CaptainRiver is built to make information easier to read: combos, hit rates, equity, and range changes should support your understanding. The final decision still belongs to the player, with position, action, opponent tendencies, and real table context in mind.
