I agree with those who are in favor of the max buy-in...that will discourage some other players trying to bully the short stacks and give you the maximum cash if you hit a monster hand. At the same time, I see why one might want to split their
bankroll...on one occasion, I had a $200 bankroll to play $1-2 at Casino de Montreal. For some unknown reason, something in the back of my head told me to buy in for only $100 at first...boy, was I glad I did that...first hand I got pocket aces...all in and lost. Took my second $100 played for about 2 hours treading water, until 10 minutes before I had to leave to meet my wife...got pocket 9s against AJ spades...flop comes with 2 spades, one being the 9...the money went all in, and this time it held for a double up and a tidy $35 profit after 2 hours of play. If I had bought in for my entire bankroll to start, I would have been out in the first 5 minutes...so, it varies, but for the most part, I buy in for the max.
