Asking bid (original) (raw)

In contract bridge, an asking bid is a convention used to seek a slam accurately. There are two types - colour asking bids and notrump asking bids. Constructed by bridge pioneer Ely Culbertson in the 1940s, they have been superseded by other methods; however, one remaining commonly used asking bid is the 5NT Grand slam force. The application of Asking bids requires making distinctions between the asking colour, the agreed trump and the two remaining side colours. Replies by partner are in accordance with a schedule of defined meanings.
