I just turned 18, and I would like to learn limit holdem during the holidays(a month and a half to kill).
I have about 250$ to spend in books and to deposit.
I have played freerolls, playmoney tables and live games for about a year and a half(probably about 100k hands) and read Winning low limit holdem by Lee jones, HOH 1 & 2.

so my questions are: what's the first book I should read, and when i'm done, what stakes should I start with? How many hands do I have to play before moving up a level, and what is the second book I should read, and when? I like to multi table, how many tables can you play and still be improving your game?

I already got PT.

And please dont anwser me that you have to consistently beat the game to move up a level, I like to have concrete goals.

this is obviously for fun, I dont intend going rich.

never been one for concrete goals myself.

if you want to do limit holdem get SSH - it goes well with Jones' book.

Save the money for the tables.

if you want to have a good reference for different games, Hellmuth's book or SS2 can be added in also.

Steve-O's post is good. What site are you planning on playing? If Stars, start at 5c/10c just to get a feel for the game.
