Absolutely you could win probably several games of heads up Texas Hold-Em poker against a professional. The strategy is simplicity itself, go all in every hand. Basically, the worst pre-flop odds you can possibly have are just under a 6% chance to win. Over five hundred games in the worst case scenario, if the odds hold you should win about 30 games with the pro. Obviously, the pro isn't going to have Aces to your covered up A 6 every time so you should win more than that amount.
