I am a college student and consider myself a decent poker player. Usually when I put my money in, I am ahead. I have played at Party, Ultimate, Paradise, and now at Pokerstars and I am tired of rookies/fish not folding to reraises with their bottom pair when it's obvious of top pair/kicker, getting called all-ins by k-4 suited and i have a-k (they get runner runner flush). I am not saying I am a pro by all means but I think I do fairly well and I just want better competition. Should I start investing more into poker and play at the higher limits? I play at the .10/.25 and deposit in 50 but I am sure I could put in 150 or so and maybe play at the .25/.50....question being, will i find less fish? People love them but they always get lucky and win and give it back to someone else. Should i just invest more so I quit getting so unlucky?
