Low stakes limit games can be rough online. It is, what it is. Low stakes. (it's also the limit range I play in) Reading books is great for advice - in general, but nothing substitutes for practice. Books cannot cover every situation. Tight table, loose, mixed, position, situation, maniacs, scared money, and the non-forgiving ever present rake.
Check the lobby before you pick a table. It shows you what the average pot sizes are running. If you're concerned about bigger pots, stick with a short table. Fewer players can often mean fewer callers and smaller pots overall.
Sometimes it is wise to watch a table before joining. Check stack sizes, watch for chip bullies, etc. Getting a partial table read before joining can be extremely valuable when working with a limited BR. Why plunk your buckeroos down on a table that doesn't 'feel' right?
In limit, also keep in mind that most low stakes players are generally not willing to fold many hands. Let a few orbits go around and protect your blinds, if you can. Gives you a better feel for the table.
Patience, patience, patience. Limit games are for grinding it out. Even playing tight, I won't get too aggressive early in a hand. There are a lot of chasers in limit games - and they do hit. Wait for the right hand -AND- position, then play your best TAG game.
Don't get discouraged with just a month under your belt. I started playing 7stud and 5draw in '69 when nl holdem tables were sitting empty at the casinos
. 1900 hands is not a very large number in determining profit and loss. A month into a new game for you and only a $30 loss isn't all that bad. There are swings in limit, just not as drastic as no limit. If you like the game, stick with it.
