Slam conventions

1.2. Slam conventions:
BW = Roman Blackwood (not Keycard). Ask for Aces.
A jump to 4NT is BW, if no FIT or new information about length in suits.
Step-responses: 0/3 A, 1/4 A, 2 A no K, 2 A + 1 K...
The next ask is the cheapest suit, for K.
Step-responses: 0 K, 1K...
The next ask is again the cheapest suit, for Q.
Step-responses: 0 Q, 1Q...
Sign offs: any non-cheap suit, or 5NT and above.
Note: After a NAT 3NT, 4NT is quantitative.
EBW = Exclusionary Roman Blackwood. Asks for A's outside the jump suit.
A double-jump is EBW, if 4NT would be BW.
Answer as to BW, but don't count the A in the jump suit.
Sign offs: a non-cheap suit or 5NT and above.
RKCB = Roman Key Card Blackwood. Asks for KC.
Note: If a FIT in 2 suits, then 6 KC's: 4A + kings of both suits.
A jump to 4N is RKCB, after a FIT or new information about length in suits.
Answers by steps: 0/3 A, 1/4 A, 2/5 A no Q trump, 2 A + Q
Next ask is the cheapest suit, for the Q of trumps, if unknown.
Answers by steps: no trump Q, yes trump Q
Note: If a FIT in 2 suits, then the major trump Q is resolved first.
Next ask is the cheapest suit, for side K's, with all other bids asking for Q or DOUB in the bid suit.
Answer: 6 of trumps no, other bids yes.
Sign offs: Any bid of the trump suit.
ERKCB = Exclusionary Roman Key Card Blackwood. Asks for KC outside the jump suit.
Answers as to RKCB, but don't count the A in the jump suit.
Sign offs: as RKCB.
CUE = Cue bids. Shows any control after a FIT - A, K, Sing or Void.
Use a CUE after NAT bids to show control in the side suit.
Principles before KC limitation:
-Skipping a suit denies control in it.
-Continuing to CUE after a skipped suit shows a control in it.
-Continuing to CUE doesn’t guarantee a MAX.
-Bidding 4 in a FIT with no skipped controls shows a MIN.
-a CUE in a previously skipped suit show a Q or DOUB.
-Jumping to 5NT shows a Void in a side suit, even # KC's.
-Jump in a suit shows a Void in the side suit, odd # KC's.
KC limitation (parity of # of KC's held by one player, aka TURBO):
-cheapest bid: 4NT (without a jump), bid in shown SING/VOID or 4 in GF fitted minor is a CUE showing an even # of KC's; Next such bid show Q trump.
-Skipping this 4NT CUE, bid in shown SING/VOID or 4 in GF fitted minor shows an odd # of KC's.
Note: After a FIT at the 5 level use 5NT just like 4NT.
-Continuing to CUE after KC limitation below the 5-level of trumps shows enough KC for slam, but missing the Q trump or equivalent, or is a CUE for grand slam. With the Q of trump Pd continues to CUE for a possible grand slam.
-Continuing to CUE after KC limitation above the 5-level of trumps shows enough KC for grand slam and the Q of trump or equivalent.
Note: If CUE after KC limitation below 5 in FIT isn't available, then 5NT cue show enough KC for slam, but missing Q trump or equivalent.
Sign offs: Any bid in trumps = missing a control in a skipped suit or not enough KC or Q trump (after 4N).
SPL = Splinter. Limited slam try with a FIT, shortness in jump suit.
Use a SPL if nothing wasted in the short suit makes slam possible.
Splinters are: a jump in a side suit after a fit, OR a double jump in an unbid suit without having previously raised, setting trumps in the process.
Principles: same as with CUEs.
Sign offs: Any bid in trumps.
Note: Any unusual jump in a usual NAT bid is also a SPL.

Discussion:
Why put slam conventions before the main system?
-> Because you need to know what to expect at the highest levels to plan your bids at the lower levels.
