Roman Keycard Blackwood

By Anders Wistrand

This is an adaptation to the Blackwood slam convention, used to ask for/show the trump King and Queen. The Key Cards are the 4 aces and the trump King. This convention is also called 3014 Blackwood and is identical to 1430 Blackwood except the first two responses are reversed (03 - 14 as instead of 14 - 30 ).

After determining trump, the Roman Keycard Blackwood initiator bids 4 NT. The responses are as follows.

RESPONSE

SHOWING

5

0 or 3 keys

5

1 or 4 keys

5

2 (or 5) keys no trump queen

5

2 (or 5) keys with trump queen

After 5 or 5 responses, the Roman Keycard Blackwood initiator may bid the cheapest non-trump call to inquire the presence of the trump Queen. Responder returns to trump to deny the trump queen.

Blackwood is good if you want to find out about missing aces and kings. If you want to find out about voids you should use cue bids instead.

After 5 and 5 the initiator can bid 5NT to ask for kings.
