    Two Notrump Opening Bid

    Uploaded by

    The document discusses responses and conventions after a 2NT opening bid. Some key points: 1. 3♣ is Puppet Stayman, asking opener to respond with their 4-card or 5-card major suit. 2. 3♦ and 3♥ transfers the responder to their 5+ card major suit, allowing the partnership to explore a major suit fit. 3. 3NT shows values but no interest in a major suit contract, planning to play the hand at the 3NT level. 4. Other bids like 3♠, 4♣, 4♦ allow the partnership to further investigate slam possibilities through additional steps like Blackwood or quantitative bids. 5

    Defending against opposing competitive bids after 2NT opening bid

    Even if uncommon, nevertheless opponents’ competitive bids are possible, whether with a
    natural meaning (overcall with a suit) or an artificial meaning (specially when opponents
    enter with a double).

    After a double

    2N double ?
    T

    Responder behaves in the same way of a 1NT doubled, that is ignores the double.
    He uses 3♣ Puppet, 3♦ and 3♥ transfer, etc.; moreover- as seen in the case of 1NT- makes use
    of redouble and over the obliged partner’s 3♣ calls:
    ◻pass= 5/6♣
    ◻3♦= 5/6♦
    ◻3♥= 5♥-5♠ SO

    After an overcall with a bid of a suit

    2N 3Suit ?
    T

    Over a real suit:


    ◻double= negative (balanced or half-balanced hand, usually with interest in M)
    ◻3/4Suit= 5+ cards, GF
    ◻CB of the overcall= ST, with shortness in the suit

    Over a conventional suit:


    ◻double= with 4+ cards in the conventional suit
    ◻3/4Suit= 5+ cards, GF
    ◻CB (of RSO)= ST, with shortness in RSO
