Hello from a newby

[JRBeav]

This is my first post but I have been lurking here for a couple weeks. I am a newer player and as such I may make a totally dumb and rediculous post from time to time (my appologies in advance).

I am looking for advice on how to best develop my game. I have read most of "Hold 'em Poker" and the NL chapter of Super Systems (most of it has not totally sunk in yet...alot of info in a short period of time). I made a $50 deposit at a lesser known poker site and ran it up to over $500 in a couple days (so I started thinking that I might know what I am doing) then I went to Party Poker and lost $150 in less than a day. Now I realize that I know just enough to be confident in my losing hands.

Currently my only interest is in tournament poker so any advice as to books, software, videos etc. that could be beneficial would be appreciated.

Thanks in advance for your help!
