2NT : negative bid (limited raise)

PDF
2NT : negative bid (limited raise)
This is a bid used by the Responder after Opener's strong two-suiter bid showing a weak hand 5-7HCP
This bid conveys to Opener :
  • either a fit in one of his suits
  • or a regular hand to play NT

This is a forcing bid for one round ... the bid of the strong two-suiter is in itself auto forcing!

Problem E4915 With only 5HCP, Game isn't possible if Opener's two-suiter is minimum (18HCP). Opener will pass because his P has informed him of his point strength.
 
 
Opener's follow on bids :
  If Opener is minimum he should rebid his opening suit
   With strength for Game :
  • without a suit fit, he signs off at 3NT
  • with a fit in Responder's suit, he can bid Game at the 4 level
  • with a suit fit, he can also continue bidding describing his hand

Problem E6619 After Responder's limited raise bid of 2NT, Opener who has a minimum (18HCP) repeats his opening minor. Responder will pass.
 
 
The Responder now knows the strength of Opener's hand and can now bid using this knowledge :
   If Opener is minimum :
  • minimum and fitted in the 1st suit - pass
  • minimum and fitted in the 2nd suit - bids 2nd suit
  • with no fit and 8-10HCP signs off at 3NT

  If Opener isn't minimum in his bid, he will continue bidding until Game
