Applying for this position also gave me occasion to update my resume. Here's what I had to say about my past two years:
Professional Poker Player.
Played tournaments and cash games in various casinos. Requires consistent, efficient, and accurate application of analytical skills encompassing the fields of psychology, game theory, statistics, mathematics, and economics. Particularly important is an understanding of risk management, rational decision-making, and statistical inference. Independently researched these topics and retrospectively analyzed my play in order to improve playing ability and expected winning rates. (2005-present)
