avoid rush tables any lower then .25/.50 cent its hard to play rush when you spend tons of time folding until you get a good hand.. then it doesnt hit.. you get bored and start playing more then you should.. if you have $20 and your looking to build bankroll i suggest sitting at the .1/.2nl tables with $2.50 and multitabling as many as you can handle..
play the premium hands only these guys dont pay attention to you folding the whole and time and finally raising.. and when you do get a good hand its more likely your not up against a monster if you get called.
