HIGH-LEVEL NOTRUMP OPENINGS
The 3NT Opening
An opening bid of 3NT is natural, based on a long solid minor plus
outside stoppers, with a total of eight or nine tricks (perhaps
assuming a favorable lead). A minimum: S-Q3 H-K4 D-K8 C-AKQJ872.
The same hand with red aces instead of red kings would be a
maximum. At least three suits must be stopped, and the weakest suit
no worse than Jxx, Qx, or singleton king.
Partner bids 4NT with 2-1/2 to 3 quick tricks, 6NT with 3-1/2:
Quick tricks: ace counts 1-1/2
king 1
queen 1/2
AQ 2
AK 2-1/2
AKQ 3
Opener Responder
3NT 4C - Gerber
4D/4H - transfer bids
4S - slam try in opener's suit
A transfer bid followed by 4NT is Roman Key Card Blackwood. The 4S
bid says responder is interested in playing a slam in opener's
suit, whichever it is. Responder might have S-AK432 H-6 D-10764
C-J83. Opener signs off in 4NT with a minimum, bids five of his
minor if in doubt, bids six of his minor with a maximum.
The 4NT Opening
An opening bid of 4NT is regular Blackwood. Starting at this level
gives the opposition less chance to intervene. With a notrump hand
containing ten sure tricks, start with an artificial two-level
opening, then bid 4NT.
The 5NT Opening
An opening of 5NT shows eleven tricks, a 4-3-3-3 hand, at least
three aces, asks partner to raise one level for every ace, king,
or queen in her hand. Responder can chance six of a suit with
nothing but a six-card suit headed by the jack, or any seven-card
suit. Opener should not "correct" back to notrump unless he has a
little card to reach partner's suit. AK2 is okay, but not AKJ.
With eleven tricks missing two aces, start with an artificial
strong opening, then bid 5NT. Partner raises only with one or two
aces.
The 6NT Opening
An opening of 6NT shows a 4-3-3-3 hand, twelve tricks, missing just
one queen. Responder can bid seven with the missing queen or a six-
card suit headed by the jack, or any seven-card suit.
With twelve tricks missing a king or ace, start with an artificial
strong opening, then bid 6NT. Partner bids seven only when holding
the missing card.
