Or are willing to lose.
Often when someone says "People have no gamble". It is code for "I can't talk them into lock games I can't possibly lose". People might be surprised how much gamble players have if they could get
fair games. It is funny, you will go in the pool room and see two C players battling it out on an even footing while the A players in the room won't play without a lock. The C players may not be betting much, but at least both players are actually gambling. I always found that a curiosity in the pool room. The only players with any heart are the weaker players. Evidenced also by how many become pray of the better players.
When was the last time you saw one of the A players in your room go off? I used to watch Danny DiLiberto play every day and he never had the best of it. He would walk into the room and make a game right away. It didn't matter what speed you played he would make a game you could actually win at.
