♠K7 ♥KQT2 ♦AKT43 ♣AJ If we open 1♦ and partner responds 1NT, partner will end up declaring 3NT. Both of
our black suits are better if we are lead into. Correct bid: 2NT.
♠AKQ3 ♥42 ♦A3 ♣AKT62 With this hand we do not
need
to be the declarer in 3NT. This hand also has a lot of potential for slam in a suit contract and opening
2NT doesn’t help us. Correct bid: 1♣
♠K3 ♥AQ2 ♦Q3 ♣AKJ632 If we open 1♣ we have an impossible rebid. Instead we just open 2NT and deal with
it. Range with a 6 card minor should be (17)18-19.
♠K ♥AQ52 ♦AQT3 ♣KQ97 Singleton King is ok.
Avoid Singleton Aces. This hand has an awkward rebid problem if you open 1♦. Correct bid: 2NT.
19 HCP. OK to open 2NT any time you have a 5 card suit.
Gavin writes:
It is important to be able to reason out what the bids mean on the fly. You will never memorizevthese
auctions because there are too many of them and they come up infrequently. Your goal should be to understand
them all as a whole and then be able to dissect an individual auction to reason out what the bids NEED to
mean.

5-4 with an unlimited point count, e.g. ♠KJ863 ♥53 ♦2 ♣AQ854
4♠ to play, e.g. ♠A75 ♥KQJ3 ♦KQ9 ♣KQT (points in partner's
short suits are wasted)

interest
4♦ good hand, flag bid for spades
4♥ good hand, flag bid for clubs
4♠ to play
4NT to play
5♣ to play
4♥ to play
4NT quantitative invite
3♠ 4+ spades
4♣ 4 hearts and 5+ clubs. This
auction has a
completely different structure because we cannot have a major suit fit. So the only suit
opener can
show a good hand in is partner’s minor. In this case we play one over keycard and control
bids.
4♦ keycard for clubs
4♥ control bid
4♠ control bid
4NT to play
5♣ to play
4♥ spade fit and slam interest, opener
can
sign-off in 4♠ or continue with control bidding
4♠ to play
4NT quantitative invite
3♣ Puppet Stayman.
3♦ at least one 4-card major
3♥/3♠ shows
the opposite 4-card major. With two four card majors, the responder would bid 4♣/4♦
4♣ both majors, slam interest (slow shows,
fast denies).
4NT to initiate slam ask in Spades.
4♦ pre-accept slam try in hearts
4NT pre-accept slam try in spades, RCKB.
4♦ both majors, no slam interest.
3NT to play. With minor suit hands that have no slam interest, we do not need
to bother showing our hand, e.g. ♠Q2 ♥52 ♦AJ9432 ♣763 Even when we are distributional, five of a minor is so
unlikely to be the best contract. With no slam interest we simply raise partner to 3NT and hope for
the best, e.g. ♠92 ♥2 ♦KJ943 ♣Q7652
3♠ invite slam with one or two minors (could
be 5/4), e.g. ♠2 ♥K2 ♦8742 ♣AK7653 or ♠2 ♥92 ♦AK742 ♣QJ653
3NT opener always bids 3NT
4♣ 6+ diamonds
4♦ 1st step: reject (I don't have a good hand),
e.g. ♠AQJ4 ♥AKJ8 ♦43 ♣KQT
4♥ ask for keycards anyways, e.g. ♠K43 ♥4 ♦AQT843 ♣K42
4♠ control bid
4NT to play
5♣ control bid
5♦ to play
4♥ keycard response (1 or 4)
4♠ keycard response (0 or 3), e.g. ♠AK4 ♥A4 ♦K943 ♣KQJ7
4NT keycard response (2 or 5 w/o ♦Q)
5♣ keycard response (2 or 5 w/ ♦Q)
4♦ 6+ clubs. Due to the limited room in this
auction, opener should not accept the slam try with 2 w/o the queen of trumps. We do not want to
have our 2+Q answer take us beyond 5 of our suit.
4♥ 1st step: reject (I don't have a good hand)
4♠ keycard response (1 or 4)
4NT keycard response (0 or 3)
5♣ keycard response (2 or 5 w/ ♣Q)
4♥ slam interest, hearts shortness, both minors
(could be
5/4). Limited room – uncomfortable suction
4♠ good hand for one of the minors
4NT which minor
4NT to play, e.g. ♠AQJ4 ♥AKJ4 ♦A97 ♣J6
5♣ to play
5♦ to play
4♠ slam interest, spades shortness, both
minors (could be
5/4)
4NT to play
5♣ to play, responder may bid slam anyways
5♦ to play, responder may bid slam anyways
4NT quantitative invite with both minors
Minor Suit Slam Auctions:
Partner has not promised 5-5 in the minors when they show both minors. You often will still want to
end the auction in 4NT when you have most of your points in the majors.
With a good hand for partner, opener may not have room to express it to partner below game.
Sometimes opener will have to go straight to slam. We should not be aggressive to show both minors
and a slam try.
There is very limited room to sort things out. No one gets all of these auctions right. If you are
having trouble with the auctions, know that even experts struggle with these auctions.
Don’t be aggressive to look for slam. The money is in staying out of bad slams. If you are too pushy
you will end up minus.
