CQ (call)

CQ is a code used by wireless operators, particularly those communicating in Morse code, (— · — ·  — — · —), but also by voice operators, to make a general call (called a CQ call). Transmitting the letters CQ on a particular radio frequency is an invitation for any operators listening on that frequency to respond. It is still widely used in amateur radio.

History and usage

The CQ call was originally used by landline telegraphy operators in the United Kingdom. French was, and still is, the official language for international postal services, and the word sécurité was used to mean "safety" or "pay attention". It is still used in this sense in international telecommunications. The letters CQ, when pronounced in French, resemble the first two syllables of sécurité, and were therefore used as shorthand for the word. In English-speaking countries, the origin of the abbreviation was popularly changed to the phrase "seek you" or, later, when used in the CQD distress call, "Calling all distress".

Caller (dancing)

A caller is a person who prompts dance figures in such dances as line dance, square dance, and contra dance. The caller might be one of the participating dancers, though in modern country dance this is rare.

In round dance a person who performs this function is called a cuer. Their role is fundamentally the same as a caller, in that they tell dancers what to do in a given dance, though they differ on several smaller points. In northern New England contra dancing, the caller is also known as the prompter.

Comparing callers and cuers

Callers and cuers serve slightly different functions in different types of dance. Improvisation in modern Western square dance calling distinguishes it from the calling in many other types of dance.

Callers in many dance types are expected to sing and to be entertaining, but round dance cuers do not sing and are expected to be as unobtrusive as possible.

Standardized dances such as round dance, modern Western square dance, and Salsa Rueda consist of a number of defined difficulty levels. Callers and cuers are responsible for knowing all of the calls or cues (respectively), also known as figures, for the defined difficulty level at which their dancers are dancing, as well as all figures belonging to lower or easier levels.

Betting in poker

In the game of poker, the play largely centers on the act of betting, and as such, a protocol has been developed to speed up play, lessen confusion, and increase security while playing. Different games are played using different types of bets, and small variations in etiquette exist between cardrooms, but for the most part the following rules and protocol are observed by the majority of poker players.

Procedure

Players in a poker game act in turn, in clockwise rotation (acting out of turn can negatively affect other players). When it is a player's turn to act, the first verbal declaration or action she takes binds her to her choice of action; this rule prevents a player from changing her action after seeing how other players react to her initial, verbal action.

Until the first bet is made each player in turn may "check," which is to not place a bet, or "open," which is to make the first bet. After the first bet each player may "fold," which is to drop out of the hand losing any bets they have already made; "call," which is to match the highest bet so far made; or "raise," which is to increase the previous high bet.
