The play speed is measured by the aggressiveness or passiveness of the players. The fast play is aggressive, the slow one – passive. Good players change the play speed all the time and that makes them unpredictable and difficult to read. Some players use the slow play to trick their opponents. When they have very strong hands, they just check or call. This strategy gives them the opportunity to make more money and provokes their opponents to attack or bluff. Actually, the slow play is a misleading (deceptive) play with very strong hand.
