Double Squeeze

by Richard Pavlicek

A double squeeze is a squeeze against both opponents with threats in three suits: one guarded only by LHO, one guarded only by RHO, and a “common” suit guarded by both opponents. The common threat must be accompanied by an entry in its own suit. Other entry conditions may also be required depending on the layout. For a detailed study see Double Squeezes.
