SUBSEQUENT BIDDING BY RESPONDER
SAYC by Ned Downey

Following opener's rebid, responder will decide if he wishes to:

  • Sign off in a part score.
  • Invite to game.
  • Sign off in a game contract.
  • Force to game and receive more information regarding opener's hand.
  • Investigate and or bid slam, etc.

Bids available for signing off in a part score are:

  • Pass.
  • 1NT.
  • A 2-level bid in a previously mentioned suit.

Invitational Bids:

  • 2NT.
  • A 3-level bid in a previously mentioned suit.

Forcing Bids:

  • A second round jump raise of partner's major suit opening bid is a game force.
  • Following a 1NT rebid by opener a reverse or a jump shift into a new suit is forcing to game.
  • A new suit at the two level or higher is forcing for one round. Note: There is one exception. 1H 1S 1NT 2C/2D is not forcing. To create a force, responder must jump shift to 3C or 3D.
  • A bid of the fourth suit at the two level or higher is forcing for one round and may be artificial. By partnership agreement, this bid may be forcing to game.

In response to a fourth suit forcing bid opener will:

    Bid responder's first suit with three cards. Jump raise with extra values.

    Rebid his own second suit at the cheapest level (weak hand). A jump rebid shows extra values.

    Rebid his own first suit at the cheapest level (weak hand). A jump rebid shows extra values.

    Bid NT to show a stopper in the fourth suit.

    Raise the fourth suit (with four cards).

Note: If responder has initiated a 2/1 auction (e.g. 1S 2C), then responder promises a second bid unless opener's rebid is at game level. This is due to the fact that opener may, of necessity, be concealing a medium hand of 17-18 points. Following opener's rebid, responder may limit his hand with a minimum rebid in NT or in a previously mentioned suit.
