Throw-In

A throw-in is the concession of a trick, usually deliberate, for strategic gain. Typically the opponent thrown in is forced to lead from an honor at the cost of a trick, or provide an entry that you lack to the hand opposite. This category includes plain throw-ins only; no squeeze element exists (except the unique one-suit squeeze) and no trump suit is involved. About the Techniques
