"My bankroll is the amount of money I would spend or lose before I got a job. It is calculated by adding my net worth to whatever I can borrow." - Tommy Angelo
I have just finished reading Tommy Angelo's Elements of Poker. I highly recommend this work, even though by doing so I reluctantly give up my advantage of book reciprocality.
This is a book I will re-read, and re-re-read, on a monthly basis. It contains everything I need.
