Take-Out Double over 1NT
Let's take the
most frequent example we meet. Opponent opens 1NT 12-14 and partner has
doubled showing middle of range or more - 13+.
This 13 HCP critical value may be adjusted according to the openers
strength. E.g. a 3rd/4th seat 1NT opening which is shaded to 11, double
is shaded to 12! With a 14-16 opening use 15 etc.
Let's first remember what partner who doubles does NOT have
While one knows partner has 13+ HCP, one can also usually expect a
somewhat flattish distributions
- With a (5 quality) 6+ card suit & 13+ HCP as he would have used Rubinsohl transfers - bid 2N, 3C, 3D, 3H (& 3S-transfer to 3NT usually with good guards & a strong 6+ card suit)
- Two 4+ card suits as he would have bid the lower
ranking - CDH <=13(opps max) HCP Bottom limit depends on
vulnerability and lengths of the suits concerned. In any distributional hand we also prefer CDH with 13-14 HCP too
- Nor will he have a 5 card Spade suit - he then bids 2
Also in the case of 5-4 with 5 Spades partner will prefer 2 CDH with 13HCP too
Responder's options following a T-O double:
Much Judgement is clearly required in this position:
with 8-11(12) and no 5+ card suit seriously consider converting partner's
double into a penalty
- With 11-12 and a good 5 card major suit bid 3 & game with Kink value more!
- Bid 2NT/3NT with (12)+ - let's take control or game with more! You will know where all the adverse points are!
- With a 5 card major suit: take-out partner's double bidding it at the 2-level <=10HCP
- Finally bid any suit when not able to stand the double
The question that needs answering is this:-
Partner's double has thrown down the gauntlet and your dilemma is:
Any subsequent double by either defender following a sequence begun ...1NT-*....is a mandatory penalty double.
- Safety first: escape the double hope for not worse than -50 or -100 or even a +90 or +110 win
- Exert a penalty: 100 NV or 200 V
- Take control: expectancy of 140+
