Opening Bid of 2 Diamonds

<p>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. </p>

<p>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.</p>

<p>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.</p>
