INOT is the first non-trivial poker bot to be released as open source (to my knowledge). It is an expert player, and placed second in the 2007 AAAI Computer Poker competition. The meat of the program are the strategy files, which specify what actions INOT should take in any given situation. Play is unpredictable because this strategy is randomized, meaning that in a given situation INOT might raise 60% of the time, call 5%, and fold 35%. The vast majority of the work was in the creation of this strategy using a Co-evolutionary algorithm, which is not included.
This program, including the strategy files are released as open source under GPL v2. The zip file contains source code and .jar files for interfacing INOT with poker academy. Additionally, INOT is compatible with the pokerserver software used in the AAAI competitions. Source, and a whuser.dll compiled for the win 32 platform are included so that INOT can be used with winholdem. Note that I do not condone the use of this software on online gambling sites.
Fell Omen 1 is similar to INOT, but has improved hand clasification.

Fell Omen 2 uses a similar hand classification scheme to Fell Omen 1. Unlike it's predicessors, it classifies different types of flops (e.g. all suits match, or two suits match and cards are high), and plays differently depending on the board.

In Addition to these bots, some additional code that I have released/posted is available.
