The good poker player plays solely for his own profit. He is not a gambler, however, because he puts his money at stake only when the odds are favorable; whereas gamblers bet their cash even at unfavorable odds, which leads them to losing most, if not all, of the cash they risked. A good poker player may lose some games, but he wins in the end. Losing is just one of the opportunities to gain more information about opponents.
There's no connection between intelligence and/or ability to a good poker player. Poker is not like chess or a bridge. And contrary to the opinion of many, poker isn't a game of luck or skill; it is a game of discipline, effort, and aggression. Therefore, a good player subdues his impulses and puts all his action toward meeting the objectives of the games, and that is, to win the maximum money available.
It's part of the game for a good player not to give anything away. He may help others, but there's still a motive there for a pay off or an eventual profit. To do this, a good player plans ahead and thinks in advance. His blueprint of a game maybe three to four games away from the actual play. In all of the games, the good player is a disciplined, virtuous deceiver and maintains an emotional consistency in every betting round. Objectively, he analyzes hands as well as his opponents, their tells, and their bets, so he could adapt to the situation.
These players are rare, and two good players rarely cross. As a matter of fact, most players, even those who have been playing for a long time, have never played against a good player. In such an event where two good players meet in a single game, their edge odds are reduced by each other. Eventually, they don't waste time trying to analyze each other they study the game and the players instead.
The strategy of a good poker player often relies on making decisions based on the impulse reactions of his opponents. Usually, an optimal move against a good player is to act opposite to your initial reactions. For instance, when undecided whether to call a good player and your impulse is to fold, the best move is to call or to raise. Here, you are building a ploy that, hopefully, would deceive good opponents in later games.
