Problem E2015 The 1 NT response has the advantage of preventing the opponents from making a Major overcall at the 1 level. It shows 7 to 10 HCP
 
 
Responding with a new suit at the 1 level
  • Required strength: 5 to 10HCP and a 4+ card suit.
  • With a 5 card Major: bid it (in general)
  • With 6 cards in ♦ : bid it
  • With 5 cards in ♦, 4 4 in the Majors, and a nice hand, bid 1 ♦
  • with more than 1 4 card suit, and
    • a weak hand: give preference to the cheaper suit (not necessarily a Major !)
    • an 'average' hand (8-10HCP) bid the cheapest Major
    • a strong hand, prefer the minor( ♦ ) .

Problem E5268 If you do not bid ♦ in the first round , you risk never having an opportunity to bid them and missing out on a fit (and possibly a slam)

Problem E5269 With 6 cards in ♦ you must bid them, even if you have a 4 card Major.
 
 
Preempt response bids
On a minor opening, they can be used even with a very weak hand (3-4HCP).
  • with a nice minor, prempt at the 3 level
  • With ♥, go to the 4 level to make the job of the opponents more difficult.

Problem E5271 An excellent preempt that really complicates the task of the opps !
 
 
Support bids
Support may be the only possible bid.
  • Simple support with 5 to 10 support points
  • Jump support with 11-12 support points . it is an encouraging support for a NT contract .

Problem E2029 minor support at the level of 3 is not forcing. It shows 11 - 12 support points. it denies a 4 card major
