# Pure Squeeze

by Richard Pavlicek

A pure squeeze requires a basic threat behind one opponent, and two ambiguous threats (guarded by both opponents) each accompanied by an entry in its own suit. The term “pure” means that none of the threats requires joint protection and no ruffing is involved during or after the squeeze. The opponent with the basic threat is triple-squeezed to abandon one of the ambiguous threats, then the matrix transforms into a double squeeze. For a detailed study see Pure Squeezes.
