Multi-time world champions Karen McCallum and Kit Woolsey explain their relay system, KK Relay, which they have used and perfected for several years. For readers not familiar with relay systems, the relay concept is quite simple: instead of making a descriptive bid, one of the partners makes a call that asks a question. His partner answers that question. That's it! Many such systems are obtuse and difficult to remember, but KK Relay has been structured in a way that both eases memory burden and increases efficiency. A must read for any system wonk.
