In this common and flexible position, entry to both hands is provided by the near threat suit. The squeeze is automatic, working against either opponent. Because of its close relationship to the automatic simple squeeze, the twin-entry squeeze is sometimes called an inverted squeeze. To make this relationship clearer, note that in the simple automatic position, there is a one-card menace lying in the near hand, while in the current position, the one-card menace lies in the far hand; as compensation, there is an extra entry in the other threat suit. The closeness of the relationship is demonstrated most clearly by noting that both endings can be played down to the same squeezed position:

Variations

1) Idle cards: In the sample ending, the North hand has an idle card in diamonds. This could be replaced by a loser in any of the four suits.

2) Extra winners: Because of the great flexibility of the twin-entry menace, adding extra winners to either threat suit in either hand has no effect whatever on the working of the squeeze (it doesn't even add ambiguity, so long as the squeezer retains the twin-entry, testing the other threat first). In practice, it is quite common to find the twin-entry threat in recessed form, with the equivalent of Ax opposite KQxx.

3) Losing squeeze card: The only additional requirement is that the squeezer be able to control any return, although now there may be some chance of ambiguity:

If West wins the club and returns a spade, all is fine, but if West instead returns a heart, the position is effectively converted into a criss-cross ending, and South will have to read the ending correctly.
