Skill and deception are two skills that one must be good at to be able to win consistently at the poker tables. If a person plays it smart they will be able to lose a hand or two here and there and still be able to come out on top.
There are a multitude of ways that a poker game can be played. Should you run into a game where few people are playing each hand and the pot does not ever grow big this would be considered a tight poker game.
