PREEMPTIVE THREE BIDS
Preemptive openings at the three level show a hand with one long
strong suit and nothing in the way of defensive strength. A suit
headed by the ace is especially undesirable, representing too much
defensive potential if partner has a singleton. Just pass and
overcall later if the hand contains an ace.
A singleton or void in a side minor is undesirable for the same
reason--too much defense. Shortness in a side major is okay.
Adequate trump support for a side major is also a flaw, especially
in first or second seat. You could miss a good contract in that
major, since partner will assume that a weak preempt lacks good
support for a side major.
The strength of a preemptive hand will vary with vulnerability,
something like this:
Unfavorable vulnerability - within 1-1/2 tricks of contract
Both vulnerable within 2 tricks of contract
Neither vulnerable within 2-1/2 tricks of contract
Favorable vulnerability within 3 tricks of contract
These can be relaxed 1/2 trick or so if partner is a passed hand.
Responses
New suit responses by an unpassed hand are forcing, except for game
bids. A 3NT response is a command for the preemptive opener to
pass--it is not a "suggestion." Responder could have a void in
opener's long suit and nine tricks of her own. A four-level minor
suit response is an asking bid:
Opener Responder
3H 3S - forcing
3NT - opener must pass
4C/4D - asking bids
When the response to a preemptive three bid is a new suit at the
three level, opener bids 3NT to show a little support (Qx, xxx)
for responder's suit. He must not raise because responder may have
only Jxx in the suit, fishing for a notrump contract, or may be
psyching. All this must be alerted, of course: "That is an asking
bid, not a telling bid. He is asking me to bid notrump with a
little something in that suit, and otherwise to rebid my suit or
show a lower-ranked feature."
