It should also be noted that awareness of the cheating techniques may not be enough to avoid being cheated. Sleight of hand experts can perform tricks that you know before you without you noticing. Also, if you do not spot any of the 'popular' maneuvers, you may feel that they were not used when you were, in fact, cheated.

Aside from awareness of the techniques, other signs that may suggest suspicious behavior are:

• An exchange of signals between two players, or any other suspicious activity (ex. passing glances, consistent spoken expressions used, etc.) that may suggest collusion.
  
• Losing with very strong hands on more than one occasion.
  
• The sight of somebody's dealing. Inexperience in sleight of hand will produce very clumsy and awkward hand gestures, or cards being held in unnatural ways. Palming, for example, requires a stiff hand to appear natural, which is difficult if the cheat is an amateur.
  
• The sound of somebody's dealing. To the very trained ear, the sound of cards being dealt can also reveal when such sleight of hand as second dealing or bottom dealing are being used. When a card is dealt, it is dealt off of the deck; the deck is beneath that card, but no card is on top of it. When a cheat is second dealing or bottom dealing a card, that card is being dealt from underneath another card. Hence, the sound is made of a card being pulled from between two other cards. One observer called this sound a "swish-click", the swish being the regular sound of a card moving off of the deck, the click being the sound of the card above it hitting the deck.
  
• Cards found underneath the table.
  
• Stubbed Counts: When enough of the deck is being dealt that the remainder of the cards (the stub) can be verified to ensure that a full deck is being used, this is also useful (ex. seven card stud with seven players leaves only three cards in the deck; if there are any less, a full deck is not being used). This is time-consuming, and not common in home games, so it would need to be used sparingly.
