Be ready for these situations and try to come up with a bid that follows the logic of the guidelines. Partner must keep bidding until you reach game. If partner has shown a truly worthless hand, you may stop at 3 of a major or higher. No clearly defined upper point limit. Partner must bid again, but these auctions are not necessarily forcing to game.
Partner can pass.
Not forcing, NOT encouraging. This asks partner to choose one of your suits. Absolutely not forcing. Partner must pass.
