OpenHoldem is able to control external rebuy-scripts with the bot, as this provides several advantages compared to hoppers:

• easy synchronisation with other bots due to built-in mutex-handling (avoiding mouse- and keyboard-conflicts).

• perfect timing, e.g. only when it is not your turn or between two hands.

• no need for the hopper to take care about your balance and simplified hopper-architecture in general.

The process to rebuy is still very specific for each casino (similar to TableMaps and lobby-handling), so there is no way to provide a built-in method that works for every casino. This casino-specific part of the job has to be done by an external rebuy-script, provided by the user. But this rebuy-script will usually become quite simple: some mouse-clicks and maybe keyboard-input are usually everything that needs to be done. For an example and possible starting-point see “RebuyDemo” in the source-tree at GoogleCode..

Many things can go wrong, when you try to rebuy, be it incorrect timing or a rebuy to the wrong value. To avoid such cases OpenHoldem does provide some security measures:

• always acquire the autoplayer-mutex before executing the rebuy-script

• optionally (as specified in the preferences) require a change in hand-number between two rebuys

• optionally rebuy only, when the user doesn’t hold cards

• optionally test heuristically for occlusion and sane balances

• optionally wait for a user-defined time between two attempts to rebuy

Once all necessary conditions are met, OpenHoldem will execute the rebuy-script, that got specified in the preferences, and pass the necessary information as command-line-parameters:

Commandline-parameters

Windowhandle of the pokertable (HWND)
UserChair (0-9)
