100BB is not nearly enough. 500BB should be your minimum. I use a 1,000BB rule myself. You can definitely build a bankroll in limit poker. I once turned $100 into $10,000 by playing mostly $3/$6 limit holdem'. I suggest you take up limit Omaha H/L. This is a game that can earn an expert player more than twice the hourly (Or BB/100) amount and requires half the bankroll to play it comfortably. If you can find a regular game at your local poker room, you can really cash in, especially given that you won't have to pay for a "bad beat drop", which will drain you in a standard limit holder' game. Give O8 a shot. It's my favorite game. I played limit holdem' for 8 years, before finding Omaha. If you are a sound winning player at limit holdem', your skills will translate in O8 very well. Besides, whats more fun than making the nuts?... Making the Nut-Nut! Good luck.
