fold even more
in fact stop calling, if its not good enough to raise with then fold it
nothing worse than calling all your money off
if you stick with that guideline and don't bluff (its not worth it at low level limits people call you anyway) then you will start winning larger pots (betting with the best hand at low limits people call you anyway) and stop calling your money off on losing hands
I still keep calling hands down when i know I have lost the hand, its one of the worst leaks of most people. I am getting better at folding them and you should by all means do it occasionally against really loose players. Don't get fooled into keeping them honest, most people will play straight forward poker, let others pay to keep them honest.
2 low cards in general even suited are worth folding practically 100% of the time, if you hit a pair it will be a low one and someone else will almost certianly usually have a higher one, all your hoping to hit is a flush and the odds
of that against the money in the pot aren't usualy worth playing and if you do hit the flush there is always the chance someone will have a higher one (this will usually result in you handing over more money than you would like to them)
I did see a site with a good list of starting hands somewhere, I will see if I can dig it out.
When i started folding a lot more than I was before I found I was winning money when i played rather than generally breaking even on most occasions.
