1 = Walsh players respond 1¨ as well, for
their hand is strong enough to bid reverse with. West still needs to alert, since he
doesn't know East is that strong.
2 = Weak jump overcalls (6- or 7-card suit, 5-10 hcp) can and should be played also when
both opponents have bid. They only have to be used with more caution, especially when
vulnerable. South must take action with this hand, in order indicate what suit North
should lead, and to give EW a hard time. If he passes, they have an easy ride to 7ª or 7NT.
3 = Should be for takeout, showing a good hand.
4 = East himself is far too strong to confine with 2ª.
5 = Roman KeyCard Blackwood, 1403-variantion.
6 = 2 (or 5) aces, without queen of trumps (spades).
7 = Asking for specific kings (up the line).
8 = §K.
9 = Believe it or not, 7NT is far better than 7ª.
7NT makes unless North holds §J962 (89% chance
of making), while 7ª fails when:
a. South holds §J962, in which case North will
make a Lightner double to get a ruff on the opening lead (occurs 11% of the time);
b. North holds §J962 and South has 4 spades, in
which event East will not be able to set up his clubs (happens 12.58% of the time);
c. either defender starts out with 5 spades (comes up 3.91% of the time).
If bridge odds were independent, this would leave East with less than 73% for 7ª. Thought bridge odds are interdependent, combining
them would favor 7NT by a substantial margin

1 = Walsh style, bypassing a 4- or 5-card ¨-suit,
unless responder is strong enough to bid reverse.
2 = South can still ask for a 4-card ª-suit
with 3§ (Checkback Stayman) or 3¨ (New Minor Forcing, our favorite convention over a
NT-rebid by opener). One of the advantages of CBS and NMF is, that North becomes declarer
in ª- and
NT-contracts.
3 = No reason to take any inquiries now.
