Be alert during winning streaks. Dealers are trained to "color up" or give high-value chips to winning players. The object is to induce the player to make larger bets on the next hand or next round. During the game players sometimes forget the true value of their chips. Later, when a session is over they realize how high some of their bets were. but then it is too late. Always remember that chips represent cold, hard cash, and not play money. So don't let them color you up if you don't want it.
