Bad Tell

A tell in poker is a change in a player’s behavior or demeanor that is claimed by some to give clues to that player’s assessment of their hand. A player gains an advantage if they observe and understand the meaning of another player’s tell, particularly if the tell is unconscious and reliable.

More often, people try to avoid giving out a tell, by maintaining a poker face regardless of how strong or weak their hand is.

This woman is a horrible poker player. She has no poker face at all.
