This is a designation for a maneuver, which establishes or is made in preparation of a pseudo squeeze during the play, generally by the declarer. A clear distinction must be drawn between a dutch squeeze and a dutch coup. The first is a form of the pseudo squeenze, which is the already established card combination in the dummy that includes the entry card or cards to be promoted creates the impression of a threat even through no such threat exits.
The dutch coup is namely the maneuver and/or the pre-play, which constitutes the establishment of such a card combination. This form of coup was originally described by Mr. Gerrit-Jan R. Förch of The Netherlands in the year 1972.
Note: Any additional information, especially any photographic material, about the bridge personality of Mr. Gerrit-Jan R. Förch of The Netherlands would be greatly appreciated.
Following is an illustration of the dutch coup as presented by Mr. Gerrit-Jan R. Förch to clarify the concept.
South, as declarer, held originally a singleton Club, which he cashed early in the play with the Ace of Clubs in dummy. On the tenth trick the declarer, in hand, played the
6, the 13th card in the suit. When he played the
6 (
the dutch coup), West discarded a Diamond since both cards were covered in the dummy, and the declarer discarded
10 from the dummy.
Mistakenly and under the false impression, East, however, was certain that South held also the Queen, which led to the conclusion by East that partner, West, held 3 Diamonds. East discarded, based upon this false assumpion, a small Diamond.
This action by the declarer, of playing the 6 and then discarding the 10 from the dummy, was the maneuver, which led to the establishment of the final three Diamonds tricks for the declarer, thereby winning all of the last four tricks.
