Look into the book Comp City by Max Rubin. In it Max outlines numerous techniques to make your play appear higher than it really is. simple things like betting more when the pit is watching (filling out rating slips) and playing at crowded tables so your money lasts longer. Casinos are more interested in the duration of your play than the number of hands you played. It is better to play 2 hours at 40 hands per hour (full table) with $25 bets than it is to play 1 hour at 100 hands per hour heads up. You put less money into action (with negative EV) and got more comp value because they rated you as a $25 player for two hours. Add that style of play with raiseing your bets only when they are watching and you could be a $50 bettor for two hours without really risking much more.
