Rosenkranz redouble

The Rosenkranz double and Rosenkranz redouble are elements of a bridge bidding convention invented by Dr. George Rosenkranz, collectively known as the Rosenkranz double.[1] The calls are made by the partner of an overcaller (the advancer) to describe his top honor card holdings in the overcaller’s suit.
