Tell (poker)
Any personal mannerisms that reveal the quality of one's hand.
E.g., constantly looking at one's hole cards is often a tell
of a poor hand. (Some players, knowing this, will at times check
their hole cards when they have a great hand and don't need
to look.). You might unconsciously play with your chips every
time you bluff. Or you might notice that another player blinks
a lot whenever he has a strong hand.
