Roman Keycard Blackwood - An adaptation to the Blackwood slam
convention, considering the trump King, Queen, and other attributes.
This convention is identical to
1430 Blackwood
excepting the first two responses are reversed (14 - 30 as opposed to 03 -
14).
1430 Roman Keycard Blackwood, Part 1 - Slam Bidding
This text will be replaced
After determining trump, the Roman Keycard Blackwood initiator bids 4 Notrump, with the
following responses:
| Response |
Meaning |
| 5C |
0 or 3 keys |
| 5D |
1 or 4 keys |
| 5H |
2 (or 5) keys without the trump
Queen |
| 5S |
2 (or 5) keys with the trump Queen |
Note: several methods are used show Voids, non-trump Kings, and the trump
Queen (with other than 2 keys).
After 5C or 5D responses, the Roman Keycard Blackwood initiator may bid the
cheapest non-trump call to inquire the presence of the trump Queen.
Some partnership agreements return to trump to deny the trump Queen while
others play the treatment reversed.
One common treatment to show useful voids includes:
| Response |
Meaning |
| 5N |
Even number of keycards |
| 6 level of void suit |
Odd number of keycards,
bidding the void suit |
| 6 level
in trump suit |
Odd number with a useful
void in a suit above trump |
Assuming the presence of all keycards and the trump Queen, the Roman Keycard
Blackwood initiator may explore Grand Slam with extra values. Several methods
are practiced by players including:
| Method |
Treatment |
| Specific
King Ask (up the line) |
After the partnership
discovers they hold all keycards and the trump Queen, the applicable
partner ("the one who knows, goes") makes a bid at the 6 level
corresponding to the rank of the lowest King held. The partnership
makes successive King rank bids up the line, skipping the rank of
missing Kings or returning to 6 in the trump suit (obviously a major)
lacking further Kings to disclose. |
| Blackwood |
Initiator bids 5 Notrump
Show Kings as in regular Blackwood style:
0-4 = first step
1 = second step
2 = third step
3 = fourth step |
Blackwood
minus trump King |
Same as above, but subtract
the previously disclosed trump King |
