1st bid of responder after a 1NT opening bid

PDF
Your partner, by bidding 1NT indicates precisely 15-17HCP with a regular hand.
Stayman and Texas transfers help you find the best game .
Zia advises advanced players to use the 3 levels Stayman with 4 cards in a Major and even occasionally with 5 cards in a Major.
without a 4 card majors: the responses are unchanged.
  • PASS with less than 8HCP
  • 2 NT with 8HCP : Game proposal
  • 3 NT from 9HCP : Game
  • 4 NT with 17HCP : Slam Proposal

 
2 Stayman Zia advises advanced players to use the 3 levels Stayman.

By convention after the 2 response, the opener will bid :
  • 2 with no 4 card Major
  • With just 1 4 card Major : 2 in that suit 2 or 2
  • 2 with 4 cards in both Majors. If the responder does not have but , he'll bid 2 or 3 NT depending on the strength of his hand. The opener will the conclude at 3 or 4 .

In case of a fit your opponents will not be aware of your 4 cards in P and of your distribution..which will make their defense much more difficult !

Conseil de Dominique sur le Texas
With a 5 card Major, 7-8HCP concentated in right suits and an irregular distribution , it is preferable to use the Stayman rather than Texas transfer. You camp will find out much easier if there is Game potential with a limit hand.
