ZZZKBot is a StarCraft AI, written by Chris Coxe. It is competing in AIIDE2015. As of October 2015, it only does the 4pool or speedling builds. It is a later version of ZZZBot after it was renamed from ZZZBot to ZZZKBot in October 2015.
4pool, or for particular opponent names it uses speedlings transitioning into mutalisks then transitions into guardians if any mutalisks die.
