Vienna coup

The Vienna coup is an unblocking technique in contract bridge made in preparation for a squeeze play.[1] It is so named because it was originally published by James Clay (1804-1873) after observing it being executed in the days of whist by "the greatest player in Vienna" — identity unknown.[2]
