Double Squeezes Few players fully understand the double squeeze, yet the concept is not that difficult. Certain basic principles apply to all double squeezes, and a mastery of the subject is well within reach for anyone who absorbs this study.
All double squeezes involve three suits that contain threats.
The common threat must be accompanied by an entry in its own suit. For the sake of discussion, assume South has the common threat. Remember that this orientation is relative to the hand with the common threat. If South has the common threat, North must hold the left threat. The reason is that if South also held the left threat, both threats against West would lie in front of him and, by the nature of all squeeze plays, South must part with a threat before West parts with a stopper.
