The idea that you can only beat games with good players makes absolutely no sense. You say you've been studying Sklansky, so you should recognize that the most profitable games (in terms of BB/hour, obviously you make more money at higher stakes) are the ones in which your opponents make the most Fundemental Theorem of Poker mistakes, i.e. the games with the worst players. You may have to "dumb-down" your play a little and make fewer sophisticated plays than you would against competent competition, but I recommend you play the lowest limit games the casino offers and make sure you're actually beating them consistently before you jump into 10-20 if you've never played live casino poker before.
