Bridge Conventions

(Lessons by Allan & Claire Whiteford)

Blackwood is a system used to help bid slams and is a mechanism for finding out how many aces and or kings are held between a partnership

Blackwood

4NT asks for the presence of Aces. The replies are:

To find out about Kings bid 5NT. The replies are:

Asking for Kings automatically commits a partnership to a slam and many players operate a variation on standard Blackwood where bidding the next suit up other than the trump suit asks for Kings.

Keycard Blackwood (KCB)

This is a refinement of Blackwood and treats the King of Trumps as a keycard.

4NT asks for the presence of Keycards i.e. 4 Aces and King of Trumps (Keycards). If trumps have not explicitly been agreed then use the last bid suit as trumps. The replies are:

Roman Keycard Blackwood (RKCB)

Many of the better players play RKCB, which asks for the 5 Keycards but also the Queen of trumps. This is a more complex system and beginners may be better keeping things simple untill they become more practised.
