You may want to try playing against some of the AIs developed by the Student Starcraft AI Tournament such as SAIDA, Locutus, CherryPi, krasi0, Iron Bot, and tscmoo. If I could make a single recommendation to future AlphaStar opponents, it would be to prep against these AIs. AlphaStar has style overlap with the AIs mentioned above, and I'd like to see a match with human better prepared for that. The SSCAIT has a weekly broadcast which demonstrates the strengths and weaknesses of AI players quite well.
