      Hello everyone,

      I would like to present to you the FL River-Solver, a tool, which allows you compute Nash-Equilibria and much more.


      Nash Equilibrium:

      The main mode of the program, it allows you to compute a Nash Equilibrium in a headsup situation on the river.

      The tool does not simplify the game in any way, like excluding mixed strategies or merging strategically distinct cards.
      The result is the unabstracted Nash Equilibrium on the river.


      - Computation of an exact Nash Equilibrium
      - Using isomorphisms for maximum speed and a lossless abstraction
      - Computation of the expected value and exploitability of the strategy

      Best Response:

      Here you can compute the best exploitive strategy against a certain opponent strategy.

      This mode gives you the best explotive strategy and it's expected value.

      Restricted Nash Response:
      The chart shows the exploitability and expected value of a restricted nash response strategy compared to a simple mixed strategy. The ratio between expected value and re-exploitability is much better for the Restricted Nash Response.

      This mode allows the computation of the best exploitive strategy against an opponent strategy given a certain re-exploitability.

      This strategy performs way better, than a mixed strategy of Nash and exploitive elements. Even for a very small re-exploitability the expected value is growing exponentially.


      - Choosing the degree of exploitability
      - Computation of the expected value and exploitability for both strategies

      Representation of the results

      The results are saved in a special format, which allows further analysis. Those files can be sent to friends and viewed with every River-Solver program.

      Price, Download and contact information

      The current price of the tool is 49€ in the Early Bird Special, funds can also be sent in Dollar.

      You can doanload the Software here: DOWNLOAD

      You will be able to test it for 5 days and might activate it with a license file later on.

      The license is valid for one compuer. The computer can be changed every 30 days.

      If you are interrested or you have questions or feedback, mail us at


      We are constantly trying to improve our program. We are especially trying to design the graphical interface accordign to your wishes.
