Complementary bidding is also known by which set of terms?

• A. Protective bidding
• B. All of the above
• C. Shadow bidding
• D. Cover bidding

Answer: (B)

Complementary bidding means bids that support and extend partner’s message about the hand, helping to steer the contract in a coordinated way even in competition. Protective bidding, shadow bidding, and cover bidding are different terms that describe this same idea from multiple angles: protective bidding guards the partnership’s plan against disruption; shadow bidding mirrors or echoes partner’s intent to reinforce the communication; cover bidding aims to blunt opponents’ interference while still signaling support for the partner’s suit or plan. Because all three describe ways to reinforce partner’s communication and coordination, the set that includes all of them is the best answer.
