The Weak 3 opener is proposing a suit to play.
The Weak 3 opener has less than 12 HCPs, a 7-card suit in clubs, diamonds, hearts or spades, with at least 5 HCPs in the opened suit.
The Weak 3 opener likely holds only 6 or 7 tricks, so the responder is expected (or hoped) to make up the difference of 3 or 2 tricks or more.
The Weak 3 opener does not know if the responder has a strong or weak hand, so the Weak 3 opener must follow the direction of the responder's bidding.
The responder assumes the Weak 3 opener has 10 HCPs.
The responder does not have to hold any cards in the opened suit - the opener already has 7 cards in the opened suit.
The responder should have at least 15+ points for a response.
Whenever one player at the table has a long suit, it is not unusual for additional players to have a long suit in addition to short suits. The bidding can be unsusual, and the player with a long suit with a higher hierarchy has a bidding advantage.
Responder has Support (1+cards) in opened suit. There are enough combined points for a game.

If the opened Suit is a
Major Suit - Responder has 2 options:
• Responder supports the major suit with a re-bid in the
major suit at the
4-level.
• If the responder has stoppers in the other 3 suits, the responder bids
3 NT . If the opener prefers to play the contract in that major suit, the responder re-bids the major suit at the
4-level.
If the opened Suit is a
Minor Suit, the responder's bid depends upon points and shape:
•
15 to 18 pts: There are enough points for a game in No Trump, but not enough points for a game in a minor suit.
Responder bids
PASS.
If the responder has stoppers in 3 of the other suits, responder bids
3 NT .
•
19 to 22 pts: There are enough points for a game in No Trump, and enough points for a game in a minor suit.
Responder bids game with
5-level Minor suit.
If the responder has stoppers in 3 of the other suits, responder bids
3 NT .

1) If the responder has a biddable 6+card major suit with at least 5+ HCPs in that major suit, responder bids that major suit with an under-bid at that
3-level Major. This is a game-forcing bid in that major 6+card suit.
2) If the responder is balanced and has stopers in the other 3 suits, responder bids
3 NT .
