DEFENSE VS STANDARD WEAK TWO BIDS
A standard weak two bid is defined as promising a good six-card
suit and at least 6 HCP. Also see DEFENSE VS UNDISCIPLINED WEAK TWO
BIDS.
A takeout double must be slightly stronger than a minimum for a one
level double. A double of one major practically guarantees at least
four cards in the other major, unless the doubler is quite strong.
Even then, three cards is a minimum holding for an unbid major. A
double of 2D should have at least seven cards in the majors, at
least four in each if the double is a little light.
A direct 2NT overcall shows 16-18 HCP. With a single stopper one
might want more than 16 HCP, and 19 HCP would not be too much.
Partner raises to 3NT with 9 HCP or so. If he passes with 8 HCP and
you miss a game, that's life. You can't do everything.
A 2NT overcall in the reopening position can be a little lighter,
but not much. Third hand could be loaded, just waiting to double
something. Besides, partner won't know what to do with 9 HCP if
you bid 2NT with anything from 14 to 19 HCP.
After a 2NT overcall, use the same conventions and treatments as
for a 2NT opening. A 3C bid is always Stayman, while a transfer
acts like a cue bid, implying first or second round control and
slam interest. With conventions "on," the normal cue bid is not
available.
With too big a hand for a 2NT overcall, double and then bid 3NT.
A 2NT bid after doubling would not be interpreted as too big a hand
for a 2NT overcall (although the range should be higher, say 17-19
HCP):
South West North East
2D Dbl Pass 2S
Pass 2NT
This sequence implies a hand with 3-4 in the majors, maybe a single
diamond stopper, and 17-19 HCP. Just pass 2S with less (or bid 2NT
instead of doubling).
South West North East
2H Dbl Pass 2S
Pass 2NT
Here too, East implies three-card spade support and only a single
heart stopper: S-AQ3 H-K4 D-A876 C-KJ54
Since you can double and then bid notrump with a big hand, a 3NT
overcall tends to be based on a solid minor. Don't "gamble" with
this bid in the direct position. Bid 3D with S-K3 H-J4 D-AKQ873
C-432, even over a weak 2S bid. You could bid 3NT in the balancing
position, knowing partner probably has a couple of high cards (but
not enough to hang you with a slam bid).
When making a suit overcall of a weak two bid, you assume partner
has 7 HCP or so. The converse is that responder generally passes
with 7 HCP or less and no good ruffing potential. It also follows
that you must make a jump overcall if an ace and a queen, or two
kings, in partner's hand will produce game.
A cue bid overcall of a weak two bid is a strong bid that is often
based on a two-suited hand. Overcall 2S with 3S holding S-4
H-AK1087 D-8 C-AQJ873. If partner bids diamonds, you bid 4H, imply-
ing a two suited hand with hearts/clubs. Don't cue bid with a hand
weaker than this. Just overcall in one of the suits and hope to bid
the other later. A cue bid can also be based on a very strong
three-suited hand.
