Byzantine Blackwood is a bidding convention in the game of bridge. Devised by Jack Marx, it is a complex version of the Blackwood convention (by which a four notrump (4NT) call asks about partner's honor card holdings). Its premise is that both aces and kings may safely be shown in response to a Blackwood-type 4NT enquiry; provided that such kings are in well-defined key or half-key suits, there being no more than two such suits. The name was chosen to express the idea that Byzantine Blackwood is a development from Roman Blackwood, by analogy with the Byzantine Empire and the Roman Empire; rather than that the convention is of Byzantine complexity. It seems to be little used nowadays (2014), most experts employing some form of Roman Key Card Blackwood.
