Do you know pokerth ? it's an open source texas holdem poker software, and I'm using it to test my bot.
For that, I have patched pokerth to add the ability to load ia from ".so/.dll" library.
I'm working on linux, but it's easy to update for windows. (dlopen, dlsym have equivalent on windows world).
To build it for windows, you will have to cross-compile it. Follow the official pokerth instruction for that.
I may build windows binaries later.
I will also add some bot code source sample
here is bot-pokerth website
Happy bot-hacking :)
