NATURAL WEAK TWO BIDS - Catherine Draper

We use an opening bid of 2D, 2H & 2S to show a weak hand usually with a 6 card suit.
Under the new regulations you need to announce “weak”.
In 1st & 2nd position you are showing 5-9 points (although you could have less if all
points are in suit and favourable vulnerability:
e.g. QJ10xxx, x, xxxx, xx at Green. Occasionally with some poor side suit holdings
you may have up to 10 HCP) In 3rd position the range is 3-12 and in 4th 9-12

The purpose of the Weak 2 is to pre-empt the opposition and to make it difficult for
them to reach the correct contract - not to concede 1100!
So, be very careful when you are vulnerable ; you must have a good suit: e.g. AKxxxx or KQ10xxx or KJ10xxx or AQ10xxx or AJ109xx or QJ109xx

REMEMBER:

A Weak Two is supposed to be a pre-emptive bid
– so if it looks too good & could stop your side from reaching a game by pre-empting partner,
you can always pass and come into the auction later.
DO NOT open 6-4 maximum strength hands or any strength with a 4 card major.
DO NOT open 6-5 hands with a weak 2 - they have far too much playing strength;
best to pass & come in on the next round. With 9 points and a good 6 card suit plus a side suit that you feel has too much playing
strength for weak 2, you can open at the 1 level: e.g.
AKJ10xx KJxxxx
x x
J109x QJxxx
xx x
With this hand you could pass and come in later. Partner will never guess that you are this strong if you open 2S Or you could open 1S.This hand is far too strong in
distribution for a weak two.
Pass and come in on the next round
with a bid to show 2 suits

WEAK JUMP OVERCALLS

You will have the same hand type to make a jump overcall as you would have to
open a weak two. Again, if you are vulnerable, you must have a good quality suit.
This makes it less likely that you will be doubled if you have chosen the wrong
moment to pre-empt. Generally players only double low level contracts for penalties
when holding good trumps & if you have a good suit yourself they will be persuaded
to try elsewhere for their matchpoints.
 
1H - 3C is a weak jump overcall 1D - 2H is a weak jump overcall 1S - 3H is a weak jump overcall 1C - 2D is a weak jump overcall

RESPONSES TO PARTNER'S WEAK TWO

As a general principle, a raise of the Weak Two suit is non-constructive. Eg. 2H - 3H could be made on
 x
 J10xx
 K9xx
 Axxx
If partner has 5-9 points and you have only 8 yourself with a singleton spade,
who do you think has all the spades and possibly enough points for game?
The 3H bid here is a further pre-emptive attempt to keep the opponents out of the bidding.
 
A change of suit at the 2 level is not forcing, but is encouraging -
ie. 2D – 2S or 2H – 2S
 
These bids would show at least 6 cards in the new suit & say 12+ points.
A fit with the opener’s suit is denied. The opener must not repeat their suit,
they can pass or support you.
 
A change of suit at the 3 level is forcing – usually game forcing
eg. 2D – 3C, 2H – 3S, 2H – 3D
 
A response of 2NT shows at least 2 cards in support of weak 2 and asks for further information
Over 2D – 2NT asks for a feature in a side suit Qxx or better ( stop for NT)
So,     2D - 2NT - 3C shows a feature in clubs - min. or max.
     2D - 2NT - 3H shows a feature in hearts - max.
     2D - 2NT - 3S shows a feature in spades - max.
     2D - 2NT - 3D either denies a feature in an outside suit
or shows a minimum hand with a spade or heart feature.      2D - 2NT - 3NT shows a maximum hand ( possibly without
an outside stop, but with a nice strong suit)
 
Over a Weak Two in a major, 2NT asks for a shortage in a side suit (singleton or void).
This time you are usually looking for 4H/S and partner is trying to get a better picture of your hand shape.
So,     2H - 2NT - 3C shows a shortage in clubs - min. or max.      2H - 2NT - 3D shows a shortage in diamonds - min. or max.      2H - 2NT - 3S shows a shortage in spades - max. as gone beyond 3H     2H - 2NT - 3H shows either a hand with no shortage or a minimum hand with a spade shortage.      2H - 2NT - 3NT shows a maximum hand without a shortage.      2S - 2NT - 3C shows a shortage in clubs - min. or max.      2S - 2NT - 3D shows a shortage in diamonds - min. or max.      2S - 2NT - 3H shows a shortage in hearts - min. or max.      2S - 2NT - 3S shows a hand with no shortage and min.      2S - 2NT - 3NT shows a max. hand with no shortage and a good 6 card suit Note that you do not show a "feature/shortage" higher ranking than your own suit unless you have maximum strength.
 
If the player after the weak two intervenes, Double is for penalties.
If the next hand doubles the weak 2, redouble shows a good hand and invites
partner to participate further. Pass and double is pure penalties. Suit bids are
all non-forcing, but 2NT is still the enquiry. Partner opens 2D, what is your response with these hands? ( we are vulnerable, opps NV)
