ive tried building a bankroll many times by playing sit n goes. I find it to be close to impossible if that is the only kind of game your playing. Sit n goes are like slot machines. You can hit big possbily. But you'll lose thousands of times before you hit big. Your chances of making money in these is very bad. Once in a while you can make a run at the jackpot but usually just let them go. I've found for good players the best way to make money is big multi table tournaments. I came 1st out of 209 at
Titan and won $307 in one shot. Not bad for 4 hours of work.
