• Every so often, it will be possible to make a jump shift at the 5-level that's below slam, but above Exclusion Blackwood. Such bids show a complete two-suiter, i.e. with two voids, and ask about significant Key Cards. Any suits which aren't known from partner's bidding until that point will be assumed to be the highest of the available options. After that partner can ask for queens by bidding the cheapest non-sign-off bid, with the same pattern of responses.
