This page is incomplete.

Partner's bid shows something like 12 to 21 total points and at least 5 of the major. Therefore, "support" for partner's major means you have at least 3 cards in that major (making a total of at least 8).

Evaluate your hand. If you have a fit with partner, add points for distribution. To determine how to respond, categorize your hand as one of the following:

  • Weak: 5- points
  • Minimal: 6–10 points
  • Invitational: 10–12 points
  • Game-forcing: 13+ points

Then consult the appropriate chart below depending on whether RHO has bid over partner's opening.

Without interference

With a very weak hand, pass.
