is a unique
in contract bridge
that occurs with an awkward defensive distribution of one suit.
It is a kind of immaterial squeeze, in which a discard does not cost a
trick directly, but gives up a position, allowing the opponents to adopt a
The first example is a one-suit squeeze in which the victim can choose
between an endplay or a simple promotion:
If the five of diamonds is played, East must choose whether to discard
the spade three or an intermediate honor.
By throwing the three East chooses an endplay
; South simply ducks a small
spade to East, who has to lead up to the king.
By throwing an intermediate honor, East allows for a promotion of the eight;
South leads the nine, West has to cover in order to avoid an endplay and the
eight will eventually become master.
Note that if the spade five and three were exchanged the squeeze still works.
East can choose between an endplay to the king, or an endplay to the eight.
