2NT opening bid

PDF
To open 2NT you need:
  • 20-21HCP
  • and a balanced hand (no 5-card major, void or singleton)

This bid is non forcing: with a very weak hand your partner will pass.

The bidding after a 2NT opening.
The responses are the same as those used after a 1NT opening except that the points needed are less (between 3 and 5HCP).
