Some callers use
Chain Thru from formations such as
Parallel Lines and want all the Centers to Trade; and all to
Cast Off 3/4.
We believe this is an invalid usage of
Chain Thru since it can be
ambiguous in several situations. For example, from a Tidal Wave, does
the caller want the Very Centers to Trade & then the Center 4 to Cast
Off 3/4, or does the caller want each side to do a Centers
Trade & all Cast Off 3/4? Also, if
Chain Thru is
allowed to mean each side Centers Trade followed by all Cast Off 3/4,
then from Twin Diamonds a
Chain Thru could be
interpreted as Centers of each Diamond Trade (since they are Centers
of their 4-dancer formation), followed by confusion, since there is no
adjacent dancer within their 4-dancer formation with whom to Cast Off 3/4.
EN: 50Někteří calleři používají
Chain Thru z formací jako třeba Parallel Lines a chtějí, aby Centers udělali Trade a všichni Cast Off 3/4.
Věříme, že toto použití
Chain Thru je chybné a v mnoha situacích nejasné. Jak je to třeba z Tidal Wave? Chce caller, aby udělali Very Centers Trade a pak Center 4 Cast Off 3/4, nebo mají Trade udělat Centers na každé straně a pak všichni Cast Off 3/4? Navíc, pokud by bylo povoleno, aby
Chain Thru znamenalo Centers na každé straně Trade, pak vyvstane problém z formace Twin Diamonds, protože z této formace by se
Chain Thru mohlo interpretovat jako Centers of each Diamond Trade (protože to jsou Centers formace čtyř tanečníků), a pak následuje zmatek, protože není nikdo, s kým by mohli dělat Cast Off 3/4.
