A bridge hand with no high cards in it is called a Yarborough hand, named after the 2nd Earl of Yarborough.
A yarborough is a whist or bridge hand with no card above a nine.

The recommended response to a 2 diamond opening bid in bridge is to bid 2 hearts if you have a weak hand, or bid 2 spades if you have a strong hand.
Unfortunately, the yarborough hand must be played. Even though you have no card higher than a nine, there is nothing in the Laws of Bridge that allows you to throw in your hand. Rather, the rare occurrence of a yarborough hand is an opportunity for a side bet, of which the traditional odds are 1000 to one. However, since you have no high cards, there is a good chance that your partner has a good hand. Do whatever you can to support your partner.
A common preferred response to a weak 2 bid in bridge is to bid at the 2-level with a strong hand or to pass with a weaker hand.

The best strategy for responding to a weak two bid in bridge is to bid at the lowest level possible with a strong hand, or to pass with a weaker hand and wait for a better opportunity to bid. It is important to communicate effectively with your partner and consider the strength of your own hand before making a decision.
A takeout double in bridge is used to show a strong hand with support for the unbid suits, inviting partner to bid their longest suit or make a bid based on the strength of their hand.
The key responses to a takeout double in bridge are: Bid a suit at the lowest level to show a strong hand in that suit. Bid notrump to show a balanced hand with stoppers in the opponent's suit. Pass if you have a weak hand and no strong suit to bid. Bid a new suit at a higher level to show a long, strong suit and invite partner to bid again.
In bridge, making a transfer bid involves using a bid to show a long suit in your partner's hand and asking them to bid in that suit. This is typically done by bidding a suit one level lower than the suit you actually want to play, indicating to your partner that you have a strong hand with a long suit in the higher bid suit.
When using the Lebensohl convention in bridge, you can respond to a weak 2 bid by bidding 2NT to show a strong hand with at least invitational values. This allows you to handle the weak bid and communicate your hand strength effectively to your partner.
