2 ♦ (or 2 ♥) response to a 1 in a major opening
After a 1 in a Major opening (in 1st or in 2nd position and with no overcall, otherwise, there is no 2/1 GF.) and a 2♦ (or 2♥) response, the bidding is now game forcing. What does the 2♦ (or 2♥) response show:
  • 1-It is basically Natural but, in practice it indicates that ♣ is the longest suit.. but may have only 4 cards in ♦ (but promises 5 in CO!)
  • 2- It shows 'opening values' given his combination of HCP and shape (and its expected fit withj yours), your partner expects there will be at least a game
    • The opener's initially focuses on showing his shape. The responder will then be well-placed to direct the partnership to the best contract.
    The priority is to decide on the suit for the final contract.

    Problem 40300: Bid 2♣. You can't raise spades with only two. The hand is wrong for NT (no ♥ stopper)--2 ♥ with only a 4-card suit is a no-no . That leaves ... 2 ♣... but fortunately the 2/1 system will give you time to investigate the right contract

    Problem E40301 2♣After 1♠ by your p; gladly bid 2♣ and force to game. your hand is great in support of spades. However, after 1♥ , content yourself with 1NT (forcing). Picture opener with, say:PI: A 7 6 CO:K J 8 7 5 CA:J 4 2 TR:K 3, and where are we going?
     
     
    1 ♥ opener's 2nd bid after a 2 ♦ response.
    Opener bids NATURALLY. If opener has a second suit (of 4 or more cards), he bids it. If he is flat, he bids NT. If he has 6+ cards in the major opened, he repeats it. No jumping... see exceptions later
  • 2- 2♥ Natural, 6+ ♥ (any strength)
  • 2- 2♠ Natural, 5+ ♥ and 4+ ♠ (any strength)
  • 3- 2NT
      Natural, 5 and 3-3-2 in the other suits (mini: 12-14 or maxi 18-19HCP)
  • 2- 3♣ Natural, 5+ ♥ and 4+ ♣ (any strength)
  • 2- 3♦ Natural, 5+ ♥ and 4+ ♦ (any strength)

    • Most of the time, there’s no need to jump, since the partnership is already forced to game.
    If required, the options are
  • 1-Jump rebid the opening suit (1♥ 2♦ 3♥)showing a "solid" 6+ card suit. This means that opposite a void, the suit can be expected to run.
  • 2- Splinter bids (1♥ 2♦ 4♣ or 1♥ 2♦ 3♠) Showing 5♥, 4+♦ and a short in the suit bid
  • 2- Jumps in NT (1♥ 2♦ 3NT) Natural, 3532 or 4531 with a 2nd zone hand (15-17HCP)
    • Problem E40302 2♦First priority is to show 5+ diamonds. Partner will bid a major next if he has four.
