[not a model]

i did this against some people at my school when we were in spain by using marked cards. this was like 7 years ago, so i dont really remember a lot, but i remember the first session they stopped playing because they felt bad for me because I WAS GETTING CRUSHED and was down like 10 bets. and i wasnt even being smart about disguising my cheating either--i was doing it POTRIPPER style and i still couldnt win. im pretty sure that eventually over the course of the trip i finished up, but we were betting like 100 pesetas or something so it was like betting quarters. anyway, in summary and conclusion, the advantage if you are trying not to be obvious seems very marginal to me. but why dont you just take a deck of cards and run 100 trials to get and idea. take you ten minutes.
