International Signals (poker)
A set of signals supposedly universally recognized by all thieves,
allowing thieves who don't even know each other to communicate
their desire to fleece the suckers, indicate their need for
particular cards, and so on. These signals are of no use in
games with sophisticated players, who are clever enough to catch
on to what is going on, and are unnecessary with "dummies,"
because they can be beat by good playing. Some thieves still
are not clever
enough to understand these concepts, however, and you may see
them in some games, particularly those in which the management
does not give its players much protection.
