I have only been playing poker a few months and started out with play money. Around a month ago I started on real money on pacific poker. I played $10 cash games. I deposited 30 dollars and started playing 2 tables at once. I added another table and another. About a week ago I had about $170 in my account. I continued playing 4 tables and moved up to $25 I now have around $300. I am a tight and fairly aggressive player and I have never lost on a session while never really make massive amounts either. I tend play the cards more than the players.

I am wanting advice on what is the best way to move up the levels and is there much difference in skill and what to expect when moving to $50 and $100 levels. I am also wanting advice on software that will help me with my own game and identifying what type of players I am against as I find it difficult identifying types of players as I multi table. Also what books would be useful in my situation

Thanks in advance
