is your play predictable?? if your playing really tight u might not be getting much out of your good hands as people know when your on something good.
do you ever bluff? ive found that occasional bluffing works for me because sometimes i take in down and if i do get called they think im a muppet and call me when im on a monster. when i say bluffing reasonable amounts tho.
then again im still pretty newbish but am making money slowly.
