Opening Bid of 2 Diamonds

An opening bid of 2 diamonds doesn't come up very often but when it does, it is highly descriptive. It says 11-15 HCP, exactly 3-3 in the majors, and 0 or 1 diamond, which means you have 6 or 7 clubs.

Responding at the 2 level is a sign-off. The 3 level in a major is invitational to game. To calculate HCP for game, discount wasted values in diamonds (J,Q, or K) but be sure to include distribution value in the other suits.

With a 5-card major, even with 0-4 points, bid the major, knowing that a fit is guaranteed. Invite to game with 5-7 HCP and jump straight to game with 8-10 and consider pushing to slam if you also have opening points.

  • pass with 5 or more diamonds, no 5-card major, and fewer than 5 HCP hoping that your opponents will jump in.
  • 2H, 2S, or 3C - sign off, no possibility of game.
  • 2N - inviting to game with a stopper in each major, 2 stoppers in diamonds, and opening count.
  • 3C - no 5-card major or stoppers in diamonds.
  • 3D - a demand bid. No 5 card major but 11+ HCP, invites opener to 3N with 14-15 HCP or 4C with 11-13 HCP.
  • 3H or 3S - invitation to game, the opener should raise to game with 14-15 HCP, otherwise pass.
  • 3N - sign off with 14+ HCP, stoppers in diamonds and both majors.
  • 4C - invitation to game in clubs.
