i play low limit games online, probably very similar to the games you describe. I only started playing 3ish weeks ago, but i'd say i've played enough to be semi-comfortable in them now.

Everyone else already gave you advice about what to play, etc. Here's my advice: believe deep in your heart that good cards will win in the end. Everytime you lose to a bad beat or a terrible chaser, you'll doubt the goodness of good cards. You will probably lose a lot to bad beats, but you will gain more back due to solid play. Believe!
