On my planet kickback after an attempted sign-off, if replier has the higher # of keycards, then he answers as if the trump-Q were asked for .



The chances of having three aces AND the trump queen and partner not knowing whether we have 0 or 3 aces are approximately 0.002 percent.

Surely step 1 asks for the queen!

However, it seems far more interesting to bid this hand with some interference. How would the strong NTers bid after a 2 (majors) overcall and a direct 4 raise from West? That is: 1NT - (2) - ? - (4). How about if the overcall that showed the majors was 2 or 2 rather than 2?

+1 for this. Anyone have any suggestions on how to find the slam now? After the 2 bid, West knows about a double fit in the majors.
As a side question, how would you proceed after this -
1NT-(2C)-?
If you continue with 2 as MSS, West still jumps in with 4. What now? Can you still find the slam without simply blasting into it? Valuable bidding space has been chewed up with the 4 pre-emp.

To ahydra, suppose your opps play a 2 overcall of 1 as 5+ spades, 4+ hearts and weak. How would you handle things if East overcalled your 1 opening with this 2 and West raised to 4 at their first turn?

Very interesting question.

To lycier, is the Q really an unimportant card in a 9 card fit for grand? If we seriously believe this, why do we not show the queen with a 9 card fit as well as with a 10 card fit? Is something under 60% always enough for you to bid a grand? Once you have decided to bid it, why not check back whether partner has the A since 7NT is then probably better, not exposing you to a potential club ruff?

Another interesting question.

I am pretty sure that after

1N-3D (both minors GF)
3S-4c (3S=diamond support)

I would eventually end up in grand. I would locate the two red suit aces and the club K, and just hope that partner either had Kx clubs or Kxxx clubs or the club Q.

I might just bid exclusion over 3S tbh, this would clearly be a situation where we count the club K as a keycard.


Systems like SAYC don't allow 1NT-3 to show both minors GF. Instead these systems use the 3 and 3 bid over 1NT to show a 6-card or longer suit and invitational to 3NT. So now the 3 bid isn't available and a different route to the slam must be found.

How would a SAYC player find the slam?

Two variations suggest themselves:
1N-3 (55+ GF)
3 - 3
4 Minorwood - 5 (2+Q)
5 - 5
5 NT - 6/NT - Not have Q
Pass

1N-3 (splinter to BOTH minors...GF+)
4 Minorwood - 5 (2+Q)
5 - 5
5 NT - 6/NT - Not have Q
Pass

Not like the finesse for 7


Neither of the options are available in systems like SAYC. How would a SAYC player find the slam?

SAYC, no special agreements:

1NT - 2 (strong notrump, stayman starts minor slam try sequences in SAYC)
2 - 3 (no major, game force with 5+ clubs)
3 - 3 (cuebids with clubs agreed)
3 - 4 (more cuebids)
4 - 5NT (another cuebid, and grand slam force looking for trump quality for 7)
6 - Pass (not particularly good trumps; would reach seven if opener held Axx Axx Axxx KQx or Axx Axx Axx Kxxx)
