are known as giveaway signals of body language which
indicate the value of a player's concealed cards.
Tell-play is an outgrowth of the science of kinesics.
If a player can read the body language of his opponents
with even a small degree of accuracy he will gain
a useful advantage. Tell-play is a science which was
pioneered by players of online poker games, where
it has proved very effective. It has also been recently
used with devastating effect at the online blackjack
games tables. The two classics on this science are
Mike Caro's website of Tells-The Body Language of
online poker games and Steve Forte's work on online
blackjack games, Read the Dealer. While no publication
specifically on tell-play in chemin de fer exists,
the methods described in these works are easily applicable
and translatable to this games. Tells are particularly
useful against amateur players. A tell does not have
to be accurate 100 percent of the time to be of value,
just more often than not.
Typical tells are lip-sucking and biting, pupil dilation,
and an overly confident posture, indicating the player
holds a favorable hand. A hand over the mouth indicates
an attempt to deceive. Folded arms are a defensive
gesture, suggesting the player is "protecting"
a poor total.
