Know poker psychology:
A good poker player must be a good psychologist. During a big money game, every kind of human emotion comes into play. I used to play stud with a player who, whenever he was dealer and had a pair back to back, would almost always fail to deal himself an upcard until his attention was called to it. He was concetrating so much on his pair that he forgot he could better the pair by drawing.
Another player at draw poker would always ask, "Whose play is it?" When he asked this question, I knew he probably had openers or a four-card flush -- at least he was going to play. When he had a poor hand he would keep quiet and put his cards down before him. These are little mannersims, if noted by the smart poker player, that will help him win because they will help him to know what to do at the proper time.
