Introduction to card cheating:
Some card sharks use sleight-of-hand moves to cheat at card games. Although the use of crooked moves is not the only method to cheat at card games, you should know how to spot these moves to avoid being cheated at. One problem with card sharks who use sleight-of-hand is that once the move is over it is difficult if not impossible to prove it ever took place. Nevertheless you always have the option of leaving the game if you suspect any form of cheating, and this is still better than being taken for a ride all the way.
